International Science and Engineering Fair
The International Science and Engineering Fair (ISEF) is the world's largest pre-college science competition, organized annually by the Society for Science and bringing together high school students from approximately 70 countries, regions, and territories to present original research projects in science, technology, engineering, and mathematics (STEM).[1][2] Founded in 1950 as the National Science Fair in Philadelphia, Pennsylvania, with 30 finalists, ISEF expanded internationally in 1958 when participants from Japan, Canada, and Germany joined, marking the beginning of its global reach.[2] Over the decades, it has grown significantly; by 2024, it featured 1,699 finalists from affiliated science fairs worldwide, held in Los Angeles, California, and in 2025, it featured 1,657 finalists from affiliated science fairs worldwide, held in Columbus, Ohio.[2][3] The competition serves as a prestigious platform for young innovators, emphasizing hands-on research conducted under mentorship, adherence to international ethical guidelines, and evaluation by expert judges in 22 STEM categories, such as behavioral sciences, energy, and robotics.[4][1] ISEF's structure begins at local, regional, state, and national affiliated fairs—approximately 400 worldwide—where students qualify to advance directly as finalists to the global event held each May.[5] The week-long fair includes project displays, judging sessions, special awards from professional organizations, and networking opportunities, culminating in grand awards that recognize exceptional achievements.[1] Awards total more than $9 million annually in scholarships, internships, and scientific tools, with the top prize—the Regeneron Grand Award—offering $75,000 to the outstanding project.[6][7] Sponsored by Regeneron Pharmaceuticals since 2019 (following Intel's long-term support), ISEF not only fosters innovation but also builds a talent pipeline, with alumni contributing to advancements in fields like medicine and environmental science.[6][8]History
Origins and Founding
The International Science and Engineering Fair (ISEF) traces its origins to the first National Science Fair, established in May 1950 in Philadelphia, Pennsylvania, by the Science Clubs of America as an activity of Science Service (now the Society for Science).[9][10] This inaugural event served as a culminating competition for high school students, drawing from local and regional fairs sponsored by cooperating newspapers across the United States.[9] The fair's initial scope was limited to individual student projects in basic sciences, featuring 30 finalists selected from 13 regional fairs, with exhibits judged separately for boys and girls to promote broad participation.[9][11] Held from May 19 to 21, the competition emphasized hands-on scientific inquiry, allowing students to present original research and experiments in fields such as biology, chemistry, and physics.[9] In the post-World War II era, the fair's early objectives centered on fostering scientific curiosity and talent among American youth, aiming to inspire future generations of scientists amid a national push for STEM education.[12] Organized with support from local newspapers like The Hartford Times and The Boston Daily Globe, it sought to build community engagement in science while providing students with recognition and resources for further study.[9] All 30 finalists received engraved gold and silver medals, while top awards included four first-place prizes of $125 each, four second-place prizes of $75 each, and four third-place prizes of $50 each in scientific equipment, totaling $1,000 in value selected by the winners.[9][12] These prizes, contributed by scientific societies and industry partners, underscored the event's goal of equipping promising young researchers. Over time, the fair evolved into a global competition, expanding its reach beyond U.S. borders.[11]Key Milestones and Sponsorship Changes
The International Science and Engineering Fair (ISEF) began its expansion in the late 1950s, transitioning from a national to an international competition when Japan, Canada, and Germany sent the first non-U.S. participants in 1958, joining 280 American finalists in Flint, Michigan.[11] This internationalization continued into the 1960s, with the event officially renamed the International Science Fair in 1965 to reflect its growing global scope and further renamed the International Science and Engineering Fair in 1971.[11] By the 1970s, participation had surged, reaching 404 finalists in 1970 from 219 affiliated fairs, and growing to 458 exhibitors by 1979, driven by increased regional competitions across the U.S. and abroad.[2][13] The 1990s saw further acceleration, with 754 finalists in 1990 from 398 affiliated fairs, alongside heightened corporate involvement that boosted funding and visibility for the program.[2] Sponsorship evolved significantly in the late 1990s when Intel became the title sponsor in 1997, rebranding the event as the Intel ISEF and supporting its expansion to over 75 countries, regions, and territories through enhanced prizes and resources until 2019.[11][14] In December 2019, Regeneron Pharmaceuticals announced its role as the new title sponsor starting in 2020, committing approximately $24 million over five years to sustain and grow the competition amid the transition from Intel.[15] This shift marked Regeneron ISEF, with the company later extending support through an additional $34 million commitment over five years announced in 2023.[16] The COVID-19 pandemic prompted major adaptations, including the full cancellation of the 2020 in-person event due to travel and gathering restrictions, affecting what would have been the first Regeneron ISEF.[17] The 2021 edition proceeded virtually, enabling remote participation and judging for finalists worldwide.[18] In 2022, the fair adopted a hybrid format in Atlanta, Georgia, where about two-thirds of participants attended in person while others joined virtually.[19] Full in-person events resumed in 2023 at Dallas, Texas, followed by 2024 in Los Angeles, California, and 2025 in Columbus, Ohio, restoring the traditional week-long gathering.[20][11][21] Overall attendance has grown dramatically since 1950, when the inaugural National Science Fair featured 30 finalists from 13 regional events, to 1,657 finalists in 2025 from 63 countries, regions, and territories, reflecting ISEF's evolution into the world's largest pre-college STEM competition.[11][22][2]Organization and Administration
Governing Body
The International Science and Engineering Fair (ISEF) is owned and administered by the Society for Science, a 501(c)(3) nonprofit organization founded in 1921 as Science Service and headquartered in Washington, D.C.[23][24] The organization underwent name changes, becoming the Society for Science & the Public in 2008 before shortening to Society for Science in 2021 to mark its centennial.[25][26] Governed by a volunteer Board of Trustees that provides strategic leadership and oversight, the Society employs a dedicated staff to coordinate its programs, ensuring alignment with its mission to inform, educate, and inspire future scientists through the promotion of scientific literacy and access to STEM education.[27][23] In its administration of ISEF, the Society for Science oversees the development and enforcement of competition rules, ethical standards, and affiliations with regional and national science fairs worldwide, maintaining high integrity in participant projects across STEM disciplines.[28][29] Staff members handle event logistics, judge coordination, and program execution, supporting an annual gathering of approximately 1,660 finalists from around 62 countries, regions, and territories (as of 2025).[1][3] ISEF serves as the Society's flagship youth STEM initiative, complementing other programs such as the Regeneron Science Talent Search (STS) for high school seniors and the Thermo Fisher Scientific Junior Innovators Challenge (formerly Broadcom MASTERS) for middle school students.[23][30][31] The Society manages ISEF's financial aspects, distributing more than $9 million in annual prizes, scholarships, and awards through sponsorships, donations, and partnerships, with the top prizes, including the George D. Yancopoulos Innovator Award of $100,000 and the Regeneron Young Scientist Awards of $75,000 each, to recognize exceptional innovation.[7][32][33] This oversight ensures sustainable funding for the event while upholding nonprofit principles dedicated to advancing youth engagement in science.[23]Affiliated Fairs and Partnerships
The International Science and Engineering Fair (ISEF) relies on a global network of approximately 360 accredited regional, state, and national science fairs (as of 2025) that serve as qualifiers, enabling students from over 60 countries, regions, and territories to advance to the competition.[5][2] These affiliated fairs must strictly adhere to the ISEF Official Rules and Guidelines, including requirements for ethical research, judging transparency, and project documentation, to ensure nominated projects meet international standards for eligibility.[34] ISEF maintains key partnerships with educational and scientific organizations to enhance its reach and recognition. Notable collaborations include Special Award Organizations (SAOs) such as the American Chemical Society, which provide additional judging and prizes for category-specific excellence, and international affiliates like the European Union Contest for Young Scientists (EUCYS), offering ISEF finalists all-expense-paid trips to compete in EUCYS events.[35][36] Affiliated fairs nominate top projects based on pre-determined quotas calculated by factors like participant numbers and regional high school population, typically allowing 1-3 projects per category depending on fair size, resulting in approximately 1,700-1,800 finalist slots annually at ISEF.[37][3] To support this network, the Society for Science offers comprehensive programs for fair directors and committees, including training on scientific review processes, display and safety standards, and annual rule updates, as well as resources through the ISEF Advisory Council for management best practices.[5][38] Diversity initiatives, such as the Advocate Program, provide year-round training, stipends, and mentorship to educators and students from traditionally underrepresented racial, ethnic, and socioeconomic groups, aiming to broaden participation from underserved regions worldwide.[39]Eligibility and Qualification
Participant Requirements
The International Science and Engineering Fair (ISEF) is open to high school students who meet specific demographic and academic criteria to ensure the competition focuses on innovative research at an appropriate educational level. Eligible participants must be enrolled in grades 9 through 12 (or the equivalent in non-U.S. systems) and must not have reached the age of 20 on or before May 1 preceding the competition year. Additionally, students may not compete with a project that is a continuation or substantially similar to one that previously received a first-, second-, third-, or fourth-place award in the same category at ISEF, though new phases of prior award-winning projects are permitted with significant additional work and proper documentation. These requirements apply uniformly to all entrants, who must qualify through an affiliated regional, state, or national science fair.[40] Projects may be conducted by individual students or teams, with teams limited to a maximum of three members, all of whom must have been part of the original team at the affiliated fair and attend ISEF if selected. Team members are expected to contribute substantially and equally to the research, with one designated as the leader to coordinate responsibilities. All team members must hail from the same school or affiliated fair to maintain consistency in oversight and eligibility verification.[40] ISEF welcomes participants from the United States and over 80 countries, regions, and territories worldwide, promoting global collaboration in STEM. To foster diversity and inclusion, the Society for Science, which administers ISEF, prioritizes outreach to underrepresented groups through initiatives like STEM Action Grants, which provide funding to expand access for students from historically marginalized racial, ethnic, and socioeconomic backgrounds, as well as scholarships and special awards at the fair. Ethical standards are paramount, requiring pre-approval from Institutional Review Boards (IRBs) or Scientific Review Committees (SRCs) for projects involving human or vertebrate animal subjects to ensure safety, informed consent, and humane treatment. Plagiarism, data fabrication, falsification, or unauthorized use of AI in generating results are strictly prohibited, with violations leading to disqualification. Use of generative AI tools must be disclosed and cited, ensuring the project reflects the student's independent work; unauthorized or excessive reliance is prohibited.[4][4]Qualification Process
The qualification process for the International Science and Engineering Fair (ISEF) operates through a multi-tiered system designed to identify exceptional student research from a global pool. It begins at the school or club level, where high school students develop and present original projects at local science fairs. Top performers from these initial competitions advance to regional or state-level events, which further narrow the field by selecting outstanding entries based on scientific merit, originality, and presentation quality.[37][4] Winners from these intermediate stages proceed to one of approximately 360 ISEF-affiliated fairs worldwide, sanctioned by the Society for Science. At these affiliated competitions—typically held between January and April—judges evaluate projects across 22 categories, nominating the top performers to ISEF. Each affiliated fair selects a predetermined number of finalists, usually 1 to 10 projects depending on the fair's size and regional population, ensuring representation from diverse areas. This step draws from over 175,000 high school participants annually in affiliated fairs alone, with about 1,600 students ultimately selected as finalists for the international event.[5][3][41] Viewed across the entire pipeline, including the school and local levels, millions of students worldwide compete in initial science fairs each year, feeding into the affiliated fairs and making ISEF qualification highly selective. International students follow the same pathway via affiliated fairs in their countries or regions, with the Society for Science supporting new affiliations to expand access where local structures are limited.[37] Nominated finalists must then complete an application process overseen by the ISEF Scientific Review Committee (SRC). This includes submitting an official abstract summarizing the project (limited to 250 words), a detailed research plan outlining methodology and safety protocols, and required forms such as Form 1 (for the research plan), Form 1A (for adult sponsor information), and category-specific checklists for ethical compliance. Deadlines for these submissions vary by affiliated fair but generally fall in late winter or early spring—often by February—for the May ISEF event, allowing time for SRC review and approval before travel arrangements. All materials must adhere to ISEF international rules to confirm the research's originality, conducted within 12 continuous months (not exceeding 18 months prior to the competition), and free of plagiarism or unsafe practices.[4][42]Competition Format
Event Structure and Schedule
The International Science and Engineering Fair (ISEF) is an annual week-long event typically held in late May, with its venue rotating among major cities across the United States to accommodate the scale of participation. The 2025 Regeneron ISEF, for instance, occurred from May 10 to 16 at the Greater Columbus Convention Center in Columbus, Ohio, spanning seven days of intensive activities.[43][44] The event unfolds in structured phases, beginning with arrival and orientation. Finalists and their delegations register on the preceding Saturday, coinciding with project drop-off logistics, followed by dedicated setup and display and safety inspections on Sunday and Monday. An opening ceremony on Monday evening officially launches the competition, setting the stage for judging over the next two days, during which the exhibit hall is open to finalists, judges, press, and select VIPs on Tuesday, and exclusively to finalists and judges on Wednesday. Thursday serves as public visitation day, allowing broader access to displays, and culminates in the special awards ceremony. The grand awards ceremony on Friday morning concludes the core program, immediately followed by project teardown and departure.[44] 1,657 finalists qualified through regional and affiliated fairs to attend, joined by over 1,000 judges, more than 500 volunteers, and a total of around 10,000 attendees including educators, family, and visitors. Since 2021, the event has integrated hybrid elements, such as a virtual project showcase activated on the Saturday before in-person activities begin, to enhance global accessibility.[3][1][44] Complementing the competitive schedule, ancillary activities promote networking and skill-building, including a STEM college and career fair on Sunday, student pin exchange sessions for cultural interaction, a midweek student mixer, and specialized symposia on topics like research documentation and science communication. These elements, along with panel discussions on innovation, provide opportunities for professional development and international collaboration among participants.[44][45]Project Types and Presentation
At the International Science and Engineering Fair (ISEF), student projects must consist of original research conducted by the participants themselves, excluding literature reviews, kit-based demonstrations, or purely informational exhibits. Each project is required to incorporate a clear hypothesis or engineering goal, detailed methods for experimentation or design, systematic data collection and analysis, and derived conclusions based on the results. This structure ensures that projects demonstrate independent inquiry and scientific or engineering rigor, with research limited to no more than 12 months of continuous work completed within 18 months prior to the competition.[40] Projects are displayed on a physical exhibit board that adheres to specific dimensional limits: a maximum width of 48 inches (122 cm), depth of 30 inches (76 cm), and total height from floor to top of 94.5 inches (240 cm), with fair-provided tables not exceeding 36 inches (91 cm) in height. The board serves as the primary visual aid, featuring the project title, a 250-word abstract summarizing the research, key graphics, photographs, and data visualizations, all of which must include proper citations for any non-original elements. Students are expected to be present at their booths during exhibit hall hours to discuss their work with visitors and peers.[46][47] A core component of the presentation is the individual or team interview with judges, during which students defend their project by explaining their hypothesis, methods, findings, and implications; all team members must participate equally and be present together to highlight collaborative dynamics and shared contributions. Supporting documentation includes a bound research logbook recording the project's progression, which must be brought to the event and made available for review but not publicly displayed, along with digital backups of forms, images, and any multimedia elements to ensure compliance and accessibility. The abstract, limited to 250 words, must be prepared after experimentation and displayed prominently on the board.[40][47][48]Categories and Disciplines
Overview of Categories
The International Science and Engineering Fair (ISEF) organizes its competitions across 22 distinct categories, encompassing a broad spectrum of scientific disciplines and engineering fields to accommodate diverse student research projects.[41] These categories allow finalists to showcase original investigations in areas ranging from biological sciences to computational technologies, with each project assigned to a single primary category based on the best fit for its focus, even if it could align with multiple areas.[41] In recent years, the total number of projects has hovered around 1,300 to 1,700 annually, distributed across these categories, resulting in approximately 60 to 80 projects per category on average.[3][22] For clarity, the categories can be thematically grouped into life sciences, which emphasize biological and health-related research; physical sciences, focusing on fundamental chemical and physical principles; engineering and technology, addressing applied innovations; and interdisciplinary fields that bridge multiple domains.[41] Life sciences categories include Animal Sciences (studies on animal physiology, genetics, and ecology), Behavioral and Social Sciences (human behavior, cognitive processes, and societal impacts), Biochemistry (molecular mechanisms in living organisms), Biomedical and Health Sciences (disease prevention, diagnostics, and therapeutics), Cellular and Molecular Biology (cellular structures, functions, and genetics), Microbiology (microbial interactions and applications), Plant Sciences (plant growth, genetics, and ecology), and Translational Medical Science (bench-to-bedside medical advancements).[41] Physical sciences categories cover Chemistry (chemical reactions, properties, and synthesis) and Physics and Astronomy (fundamental laws, mechanics, and celestial observations).[41] Engineering and technology categories encompass Biomedical Engineering (devices and systems for health applications), Earth and Environmental Sciences (geological and atmospheric processes), Embedded Systems (microcontroller-based hardware integration), Energy: Sustainable Materials and Design (renewable energy technologies and efficient materials), Engineering Technology: Statics and Dynamics (mechanical structures and motion analysis), Environmental Engineering (solutions for pollution control and resource management), Materials Science (novel material development and properties), Robotics and Intelligent Machines (automation, AI, and machine learning systems), and Systems Software (algorithm design and software engineering).[41] Interdisciplinary categories include Computational Biology and Bioinformatics (data-driven biological modeling and genomic analysis, with recent emphases on AI integration post-2020), Mathematics (theoretical and applied mathematical models), and Technology Enhances the Arts (innovative tech applications in artistic creation and preservation, introduced in 2023).[41][49] This structure ensures comprehensive coverage of STEM fields while adapting to emerging areas like computational tools in biology.[41]Rules and Guidelines for Projects
All ISEF projects must adhere to strict safety protocols to ensure the well-being of participants, researchers, and the environment. Risk assessments are required for any use of chemicals, biological agents, or other potentially hazardous materials, detailing safe handling, storage, and disposal procedures in compliance with local, state, and federal regulations.[40] For biological agents, projects involving potentially hazardous biological agents (PHBAs) necessitate approval from an Institutional Biosafety Committee (IBC) and, for Biosafety Level 2 (BSL-2) agents, supervision by a Qualified Scientist.[40] Hazardous substances, including toxic chemicals or pathogens, cannot be released into the environment, and all waste must be disposed of according to established guidelines.[40] Ethics rules emphasize the protection of human subjects and vertebrate animals in research. For human participant studies, Institutional Review Board (IRB) approval is mandatory prior to any interaction, such as surveys, observations, or experiments, with IRBs comprising at least an educator, school administrator, and a medical or mental health professional.[50] Informed consent must be obtained from all participants, including written parental permission and child assent for minors, outlining potential risks, benefits, voluntary nature, and the right to withdraw at any time; waivers are permitted only for minimal-risk, anonymous studies.[50] Prohibited activities include medical diagnoses, administration of medications, blood draws (except from the student researcher themselves), and use of unapproved diagnostic tools.[50] For vertebrate animals, Institutional Animal Care and Use Committee (IACUC) approval is required for studies conducted at regulated research institutions, while local Scientific Review Committees (SRCs) oversee school, home, or field-based work, often including a veterinarian.[51] Animal care must follow the "Four Rs" (Replacement, Reduction, Refinement, Respect), ensuring humane treatment in clean, ventilated environments with daily monitoring, adequate nutrition, and veterinary consultation for any health issues; no more than slight or momentary pain/distress is allowed, and euthanasia must be performed by qualified professionals.[51] Projects involving endangered species, invasive organisms, toxicity testing, or predator-prey experiments are strictly prohibited.[51] Intellectual property guidelines mandate that all projects represent original student work, conducted independently or under qualified supervision, with clear delineation of contributions from mentors, collaborators, or prior research in the project documentation.[40] Plagiarism, fabrication of data, or unauthorized use of artificial intelligence in generating results is forbidden and can result in disqualification.[40] Proper citations are required for all sources, including mentors' guidance, published works, patents, or unpublished data, ensuring respect for copyrights and intellectual contributions.[40] Recent updates to the rules, particularly influenced by the COVID-19 pandemic, have enhanced virtual submission processes since 2021, allowing affiliated fairs to conduct evaluations digitally with verified electronic signatures and online portals for paperwork to facilitate broader participation.[4] Additionally, the guidelines encourage diverse mentorship by promoting inclusive roles for qualified scientists from varied backgrounds to support underrepresented students in research.[28] These changes, reflected in the annual International Rules and Guidelines (latest for 2026), aim to maintain rigorous standards while adapting to modern educational needs.[4]Judging Process
Criteria and Evaluation Methods
Projects at the International Science and Engineering Fair (ISEF) are evaluated using a structured rubric that differs slightly between science and engineering categories, with each totaling 100 points to ensure a comprehensive assessment of originality, rigor, and communication. For science projects, the criteria include research question (10 points), design and methodology (15 points), execution (20 points), creativity and impact (20 points), and presentation (35 points, split as 10 for the poster and 25 for the interview). Engineering projects follow a parallel structure: research problem (10 points), design and methodology (15 points), execution (20 points), creativity and impact (20 points), and presentation (35 points). These criteria emphasize the project's scientific or engineering merit, focusing on clear purpose, methodical approach, data-driven results, innovative potential, and effective conveyance of findings.[52] The evaluation process unfolds in two primary stages to allow for both independent review and interactive assessment. Initially, judges conduct a pre-interview review of the project's abstract, display board, student notebook, and required forms (such as Form 1C for continuation projects and Form 7 for risk assessment), enabling an preliminary evaluation of the project's foundation and documentation. This is followed by a 15-minute in-person interview, where finalists discuss their work with judges, addressing questions on methodology, challenges, and implications to demonstrate depth of understanding. Category-specific scoring ensures alignment with disciplinary standards, such as biological versus physical sciences.[52][53] Quantitative aspects of projects receive particular scrutiny under the execution criterion, where judges assess the rigor of data collection, analysis, and reproducibility, including the application of appropriate statistical methods to validate results. For instance, experimental projects must demonstrate robust handling of variables, error analysis, and statistical tools to support conclusions, prioritizing validity over mere volume of data. This focus ensures that claims are substantiated through reliable quantitative evidence rather than anecdotal observations.[52] To promote fairness, the judging process incorporates multiple reviews by at least two judges per project, with conflicts of interest explicitly addressed through disclosure requirements and recusal protocols. Scoring is based solely on the current year's contributions for multi-year projects, and both individual and team entries are evaluated using the same standards without differentiation, minimizing biases related to project scale or collaboration. The overall methodology is designed to be transparent, with judges attesting to ethical conduct and decisions finalized through consensus where needed.[54][52]Judges and Panel Composition
The Regeneron International Science and Engineering Fair (ISEF) engages over 1,000 volunteer judges each year to evaluate the research projects of its finalists. These judges are recruited through an annual application process that opens in January, requiring submission at least 10 days prior to the event in May.[53] Qualified applicants must possess at least six years of professional experience following a bachelor's degree, hold a Ph.D., M.D., or equivalent advanced degree with relevant expertise, or be graduate students with four or more years of doctoral research or within one year of dissertation defense. The pool includes university faculty, scientists, engineers, and industry researchers, but excludes K-12 educators and individuals affiliated with affiliated science fairs to ensure impartiality. All judges are required to complete conflict-of-interest disclosure forms and adhere to an ethics statement, in addition to undergoing background screening.[53] Judging panels are structured around ISEF's 22 categories and subcategories, with each panel dedicated to a specific discipline to facilitate expert evaluation. Head judges lead these panels, overseeing the process to maintain fairness, coordinating category meetings, and guiding deliberations. Judges participate in mandatory training sessions on the day before evaluations begin, covering the event's protocols and standards.[53][3] The scale of judging has expanded historically alongside the fair's growth, from a modest number of evaluators in the 1950s for the inaugural National Science Fair with 30 participants to the current cadre of more than 1,000 professionals assessing 1,334 projects presented by 1,657 finalists from 63 countries, regions, and territories, as in the 2025 event.[12][1][22]Awards and Recognition

These alumni exemplify ISEF's role in fostering diverse talent, with women and underrepresented minorities achieving high-impact roles in STEM fields like biotech and AI.[67]Top Prize Winners
The International Science and Engineering Fair (ISEF), originally launched as the National Science Fair in 1950, saw its top prizes in the pre-1997 era dominated by projects in biology and chemistry, with a particular emphasis on foundational life sciences during the 1950s. Winners often explored topics such as plant growth responses to environmental factors, microbial behavior, and basic physiological processes in animals, reflecting the era's focus on empirical observation and early ecological studies. These awards were primarily claimed by U.S. students, as international participation was limited until the fair expanded globally in 1958, when countries like Japan, Canada, and Germany joined.[68] Since Intel's sponsorship began in 1997, the top prize—initially the Gordon E. Moore Award and later the George D. Yancopoulos Innovator Award—has highlighted groundbreaking high school research, with detailed records available from that period onward. Notable examples include Jack Andraka's 2012 development of a low-cost sensor for early pancreatic cancer detection and Ionuț Budișteanu's 2013 AI-based self-driving car system. In 2020, due to the COVID-19 pandemic, ISEF transitioned to a virtual format without a traditional top prize ceremony; instead, all 1,300+ finalists received equal scholarships to recognize their work. By 2024, Grace Sun earned the top honor for her project on doping in organic electrochemical transistors, advancing materials science for bioelectronics. In 2025, Adam Kovalčík received the top $100,000 prize for "Total Synthesis of Novel Antivirotics," a chemistry project developing efficient antiviral drugs.[69][55] Over time, ISEF top prizes have shown clear trends, including a rise in international recipients, with more than 40% of finalists from non-U.S. locations by the 2020s, drawn from nearly 70 countries in recent competitions. Biomedical Engineering has emerged as a dominant category, accounting for several top awards due to its applications in health diagnostics and treatments, while computational and AI-driven projects have gained prominence amid technological advances.[69] The Gordon E. Moore Award for Positive Outcomes for Future Generations, supported by the Gordon and Betty Moore Foundation since 2021 (with roots in Intel's earlier sponsorship), recognizes projects with lasting environmental or societal impact. Examples include the 2023 award to Natasha Kulviwat for engineering yeast to capture atmospheric carbon dioxide, promoting sustainable carbon sequestration; the 2022 team of Napassorn Litchiowong, Chris Tidtijumreonpon, and Wattanapong Uttayota from Thailand for a low-cost water purification system using natural materials; and the 2024 duo of Justin Huang and Victoria Ou for an ultrasonic filtration device removing microplastics from water flows. Earlier iterations from 2010 focused on innovative science with broad potential, such as Amy Chyao's 2010 quantum dot applications for displays. Full lists from 2010 onward highlight themes like renewable energy and health equity.[70][57]| Year | Winner(s) | Project Title | Category |
