International Genetically Engineered Machine
The International Genetically Engineered Machine (iGEM) is an annual global competition in synthetic biology, founded in 2004 at the Massachusetts Institute of Technology (MIT) as an extension of a 2003 undergraduate course, where multidisciplinary student teams design, build, test, and present genetically engineered biological systems using standardized parts to address challenges in areas such as health, environment, and sustainability.[1][2] iGEM operates through collegiate and high school divisions, involving teams of undergraduate, graduate, and high school students who work over several months to develop projects documented on team wikis, with judging based on scientific achievement, human practices integration, and presentation at regional and international events culminating in the Grand Jamboree.[3][4] In 2025, the competition included over 400 teams from more than 50 countries, engaging nearly 7,000 participants, reflecting its growth from just five teams in its inaugural year.[4][5] The competition emphasizes engineering principles applied to biology, promoting open-source sharing of biological parts via the iGEM Registry and fostering skills in interdisciplinary collaboration, ethics, and entrepreneurship.[4] iGEM has produced over 75,000 alumni worldwide, many of whom have contributed to the synthetic biology field, including founding more than 250 biotechnology companies such as Ginkgo Bioworks.[6] Its impact extends to advancing biosafety, biosecurity, and education in the bioeconomy, with official recognition in reports from the U.S. National Academies and Department of Defense for driving innovation in synthetic biology.[2]Origins and History
Founding and Early Development
The International Genetically Engineered Machine (iGEM) competition originated in January 2003 as an Independent Activities Period (IAP) course at the Massachusetts Institute of Technology (MIT), titled "Synthetic Biology Lab: Engineered Genetic Blinkers." This month-long undergraduate course, led by instructors Drew Endy, Tom Knight, Randy Rettberg, and Gerald Sussman, aimed to apply engineering principles to biology by having students design and build simple genetic circuits using standardized biological components. A key innovation introduced during the course was the BioBrick standard, a modular assembly method for genetic parts that allows reliable and predictable construction of synthetic biological systems, as detailed in Tom Knight's 2003 specification for idempotent vector design. The course also established the initial Registry of Standard Biological Parts, beginning as a shared spreadsheet to document and share these components, fostering an open-source approach to synthetic biology.[7][8][9] In 2004, the course evolved into the first iGEM summer competition, expanding participation beyond MIT to include five undergraduate teams from U.S. institutions: Boston University, Caltech, MIT, Princeton University, and the University of Texas at Austin. Running from June to November, the event challenged teams to construct genetic systems from BioBricks while emphasizing responsible practices, including the early integration of "Human Practices"—iGEM's framework for addressing ethical, safety, and societal implications of genetic engineering to ensure secure and beneficial applications. By the competition's end, the Registry had grown to include about 50 documented parts, demonstrating the feasibility of collaborative part-sharing among teams. This inaugural event highlighted safe engineering by incorporating principles to obscure detectable "footprints" of genetic modifications, reducing risks of unintended identification or misuse.[10][1][10] By 2005, iGEM had transitioned into a structured annual competition, attracting 13 teams from four countries—including the first international participants from Canada, Germany, and the United Kingdom—marking its growth from a U.S.-centric class project to a global platform for synthetic biology education. The iGEM Registry was further formalized that year as a centralized online resource for part documentation, enabling teams to contribute, access, and refine BioBricks for reuse across projects. A significant early milestone occurred in 2008, when the competition hosted 84 teams from 21 countries worldwide, solidifying iGEM's international scope and its role in standardizing safe, interdisciplinary genetic engineering among undergraduates.[11][1][12]Expansion and Milestones
In 2012, the iGEM competition separated from the Massachusetts Institute of Technology to establish the independent iGEM Foundation, a nonprofit organization dedicated to advancing synthetic biology through education and competition, with Randy Rettberg serving as a pivotal figure in its leadership and development.[13][1] The competition experienced rapid international expansion following its early years, growing from 84 teams in 2008 to 353 teams by 2019, representing participants from more than 40 countries across six continents.[14][15][16] Key milestones marked this period of growth and adaptation. In 2011, iGEM introduced a dedicated High School track to engage younger students, starting with five teams from the United States and expanding to 120 high school teams by 2024.[17] Around 2013, the competition added an Overgraduate track to accommodate graduate students and participants over 23 years old, broadening eligibility while maintaining separate evaluation sections from undergraduates.[18] In response to the COVID-19 pandemic, the 2020 Giant Jamboree transitioned to a fully virtual format, hosting 249 teams through online presentations and collaboration tools from November 14 to 22.[19] By 2025, iGEM reached new heights with over 400 teams participating globally, reflecting its sustained scale and impact.[20] That year also saw the launch of a fully independent High School Competition, held at the Paris Convention Centre from October 28 to 31, featuring tailored resources like the White List for safe organisms and integration with collegiate Villages for cross-level collaboration.[21] Complementing this, iGEM introduced the Beta version of its redesigned Registry of Standard Biological Parts in August 2025, a cloud-native platform enhancing accessibility and data management for synthetic biology projects.[22] Throughout the 2025 season, the competition continued to emphasize multidisciplinary approaches, integrating biology, engineering, computer science, and social sciences in team projects to address real-world challenges.[23]Organizational Framework
iGEM Foundation Governance
The iGEM Foundation was established as an independent non-profit organization in 2012, having spun out from the Massachusetts Institute of Technology (MIT) where the competition originated. Headquartered at 45 Prospect Street in Cambridge, Massachusetts, the foundation operates as a 501(c)(3) entity focused on synthetic biology initiatives. Its board of directors includes key founders such as Drew Endy (director), Tom Knight, and Randy Rettberg (President Emeritus), as well as the current President and CEO Nemanja Stijepovic and other members who provide strategic oversight and continuity from the program's early development.[24] The foundation's mission centers on advancing synthetic biology by fostering education, hosting international competitions, and promoting open-source resources to encourage innovation and accessibility. Central to this is the maintenance of the iGEM Registry, a public repository of standardized biological parts that supports global research and collaboration. Additionally, the foundation emphasizes biosafety and biosecurity, developing guidelines to ensure responsible practices among participants and mitigating potential risks in synthetic biology applications. Funding for the iGEM Foundation derives primarily from corporate sponsorships by biotechnology firms, including Thermo Fisher Scientific and Twist Bioscience, which provide financial and material support. Grants from philanthropic organizations also contribute to operational sustainability. Team registration fees further bolster resources, enabling the foundation to scale its programs without compromising its non-profit status. In its operational roles, the foundation coordinates the annual iGEM Jamboree, handling event logistics, venue arrangements, and participant accommodations to facilitate global gatherings. It oversees the ongoing curation and accessibility of the iGEM Parts Registry, ensuring the collection of genetic designs remains a vital, community-driven asset. Enforcement of safety guidelines is another core function, with dedicated committees reviewing protocols to uphold ethical standards across all activities.Team Eligibility and Divisions
The iGEM competition is open to student-led teams worldwide, where all participants must be at least 13 years old as of March 31, 2025, and affiliated with accredited educational institutions such as high schools or universities.[25] Teams are required to be primarily driven by students, with advisors and principal investigators providing guidance, safety oversight, and administrative support but not leading the project development or decision-making.[25] [26] Competition participation is divided into two primary tracks: the High School Division and the Collegiate Division, each designed to accommodate participants at different educational stages.[3] The High School Division is for teams composed entirely of high school students as defined on March 31, 2025, and in 2025, it launched as an independent competition to better align with the resources, facilities, and educational constraints typical of secondary school participants.[25] [26] High school teams must restrict their projects to organisms and components listed on the iGEM White List, excluding higher-risk elements like BSL-2 organisms or human/animal samples.[26] [27] The Collegiate Division is subdivided into Undergraduate and Overgraduate categories based on participant age as of March 31, 2025.[25] Undergraduate teams consist exclusively of members aged 23 or younger, typically bachelor's-level students, while Overgraduate teams include at least one member over 23, encompassing master's, PhD, and postgraduate participants.[25] Collegiate teams in 2025 are required to integrate human practices into their projects, investigating ethical responsibilities, stakeholder engagement, and broader societal impacts as a condition for achieving silver or gold medals.[26] Teams across divisions generally comprise 8 to 15 members with multidisciplinary expertise, including fields like biology, engineering, computer science, and ethics, to foster collaborative synthetic biology projects.[25] Special participation tracks exist for non-traditional affiliations, such as community laboratories—which must be legally incorporated entities with access to BSL-1 facilities and safety training—and commercial teams organized by companies to support student innovators.[25]Competition Mechanics
Registration and Project Phases
The registration process for the International Genetically Engineered Machine (iGEM) competition opens in January each year, allowing teams to secure participation through a tiered system of deadlines and fees to encourage early commitment. For 2025, early bird registration, offering discounted fees, closed on February 15; regular registration ended on March 31; and the final deadline was May 31 at 09:00 CDT, after which no further teams could join.[28][29][25] Teams initiate registration via the official iGEM platform, where the primary Principal Investigator (PI) creates or accesses an account to start the application. This requires submitting a team profile, including a unique team name (limited to 20 characters, using letters, numbers, and hyphens), team division (such as Collegiate, High School, or Community Lab), affiliated institution(s), and primary location; payment of the registration fee follows, varying by period and division (e.g., lower for early registration).[25][25] Once registered, teams follow a defined annual timeline for project development, structured around an off-season and three progressive phases to guide ideation, execution, and completion leading to the Grand Jamboree. The off-season (December to January) emphasizes preparatory activities, such as contacting iGEM ambassadors for support, debriefing prior projects if applicable, recruiting members, securing a PI, and initiating fundraising to build team capacity.[30] Phase 1 (February to May) centers on project ideation and foundational planning, where teams brainstorm ideas, integrate human practices (e.g., ethical and societal considerations), assign roles and tasks, and review competition rules to align their vision with iGEM standards.[30] Phase 2 (June to August) shifts to active development, including laboratory experiments, modeling, DNA synthesis and ordering, construction of BioBricks for submission to the iGEM Registry, and initial documentation on the team wiki; teams must complete safety training during this period to comply with institutional and iGEM safety policies before commencing wet lab work. An example of interim deliverables is the project promotion video, due August 13, 2025, which showcases early progress.[30][31] Phase 3 (September to October) focuses on rigorous testing, iteration, and refinement of the project, alongside finalizing wiki content, Registry part pages, and other documentation to demonstrate achievements; key requirements include submitting the final project safety form by September 3, 2025.[30][31] For the 2025 season, post-Jamboree wiki access was extended, with a thaw on November 9 allowing updates until the archive date of December 10.[31]Deliverables and Presentation Requirements
Teams participating in the International Genetically Engineered Machine (iGEM) competition are required to produce a set of core deliverables that document their synthetic biology projects, promote open-source collaboration, and ensure responsible practices. The primary documentation output is the team wiki, a comprehensive online platform hosted on iGEM servers that details the project's background, design, experimental methods, results, and contributions to the field. Wikis must adhere to Creative Commons Attribution 4.0 licensing, incorporate standard judging pages, and include all project data, images, and code, with source repositories managed via GitLab for version control and automated deployment. Edits to the wiki are frozen on October 8, 2025, at 11:00 EDT, thawed on November 9, 2025, at 10:00 EST for final updates including Grand Jamboree outcomes, and archived on December 10, 2025, at 10:00 EST.[32] Another essential deliverable is the submission of genetic parts to the iGEM Registry of Standard Biological Parts, where teams document novel or improved BioBricks, including sequences, design notes, and experimental validation data to facilitate reuse by future teams. These part pages must be created and editable until the December 10, 2025, archive deadline, emphasizing the competition's commitment to building a shared repository of modular biological components. Safety forms form a critical component, requiring teams to complete the Project Safety Form outlining biosafety risks, mitigation strategies, and compliance with local regulations; the Check-In Form for mid-season updates; and, if applicable, the Animal Use Form detailing ethical animal handling protocols. These ensure projects meet biosafety levels and responsible conduct standards, with submissions mandatory for competition eligibility.[33][26] Human practices forms complement these by mandating documentation of ethical, social, equity, diversity, and sustainability considerations integrated into the project lifecycle. Teams must report interactions with stakeholders, risk assessments for societal impacts, and efforts to address inclusivity, such as diverse team composition or community engagement, submitted via dedicated forms to highlight the responsible innovation ethos of iGEM. All deliverables underscore open-source principles, with wikis and registry entries publicly accessible to foster global collaboration in synthetic biology. Teams must also submit a 15-minute presentation video by October 15, 2025, providing an overview of their project for judges to review in advance of the Grand Jamboree.[34][26][31] Presentation requirements at the Grand Jamboree culminate the competition's showcase phase, where teams deliver live summary presentations, poster displays, and booth exhibitions to communicate their work to judges, peers, and the public. Each team delivers a 5-minute live summary presentation followed by a 20-minute question-and-answer session during judging rounds, focusing on project overview, achievements, and human practices integration, with slides prepared in advance and delivered via provided equipment. Poster displays involve showcasing project summaries on digital or printed posters as part of booth setups, allowing for detailed discussions during dedicated exhibition time slots. Booth expos, a highlight of the event, occur in 15 themed "villages" organized around topics like environment, health, and manufacturing, where teams set up interactive displays including posters, software demos, videos, and hardware prototypes to engage attendees in conversations about their innovations.[26][35] The 2025 Grand Jamboree, held from October 28 to 31 at the Paris Convention Centre in Paris, France, structures these presentations across multiple days: initial judging sessions for summaries and Q&A, followed by village-based booth expos for networking and feedback, culminating in a final day show celebrating achievements and an awards ceremony recognizing outstanding contributions. This format facilitates interdisciplinary exchange among over 5,000 participants, including students, advisors, and industry experts, while emphasizing ethical dimensions through required mentions of equity, diversity, and societal impacts in presentations.[36][37][38]Evaluation Process
Judging Criteria
The judging criteria for the International Genetically Engineered Machine (iGEM) competition evaluate teams based on their project's innovation, technical execution, and broader societal implications, ensuring that synthetic biology efforts are responsible and impactful.[26] Core criteria encompass project design, which assesses the novelty, feasibility, and potential real-world application of the proposed solution using synthetic biology principles; execution, focusing on the development of a working prototype, rigorous experimental data, and reproducibility; and human practices, which require teams to evaluate societal impacts, including equity assessments by identifying affected communities, potential exclusions, and ensuring inclusivity through diverse stakeholder consultations.[39][40] The scoring rubric is structured around medal levels to recognize progressive achievement. To earn a Bronze medal, teams must complete all required deliverables—such as their wiki, presentation video, judging form, and participation in a judging session—while documenting project attributions and making a verifiable contribution to the iGEM community, such as improving Registry parts or educational resources.[39] Silver medal criteria build on Bronze by requiring demonstrated engineering success through at least one iterative design-build-test cycle and integration of human practices that reflect on the project's responsibility and positive societal influence.[39] Gold medals demand fulfillment of Bronze and Silver requirements, plus excellence in at least three special prize categories, including one in general biological engineering (e.g., advanced modeling or safety innovations) and one in a specialization track (e.g., diagnostics or climate solutions), evaluated for outstanding depth and impact.[39] Special judging elements include safety, where all teams must manage biosafety risks and high school teams are limited to approved organisms on the iGEM Whitelist to enhance accessibility and reduce hazards, and collaboration, which is assessed through documented interdisciplinary or inter-team partnerships that enhance project outcomes.[26][27] The evaluation process begins with pre-Jamboree reviews of teams' wikis, videos, and judging forms by expert judges to assess medal eligibility and special prize potential.[26] This is followed by on-site assessments at the Grand Jamboree, where judges observe poster sessions, oral presentations, and live demonstrations to score technical rigor, clarity, and engagement.[26] Medals are awarded based on a majority vote among judges, with ties resolved in favor of teams.[39] In 2025, updates emphasize high school-specific criteria, including an independent competition track with tailored village groups (e.g., focused on diagnostics or climate crisis) and stricter adherence to the Whitelist to promote safe, accessible participation for younger teams.[26] Additionally, greater weight is placed on interdisciplinary collaboration, highlighted by the introduction of a new Art & Design Village to encourage integration of diverse perspectives, such as artistic or ethical inputs, into synthetic biology projects.[26]Awards and Recognition Categories
The iGEM competition recognizes participant teams through a tiered system of medals and prizes that reward achievement across core project elements, innovation, and broader impacts. Medals—Bronze, Silver, and Gold—are awarded based on progressive fulfillment of judging criteria, emphasizing completion of deliverables, engineering rigor, human practices integration, and excellence in selected special prizes. To earn a Bronze Medal, teams must complete all required deliverables, including a wiki, presentation video, judging form, and session participation, while providing attributions and a useful contribution to the synthetic biology community.[26] Silver Medals build on Bronze requirements by demonstrating at least one engineering design-build-test cycle and addressing human practices responsibilities for societal benefit. Gold Medals require meeting all prior criteria plus substantial work toward three special prizes, with at least one from general biological engineering and one from specialization tracks.[26] Special prizes highlight excellence in specific aspects of synthetic biology projects, allowing teams to select up to three categories for evaluation to showcase diverse strengths. These elective prizes are divided into general biological engineering (e.g., Best New Basic Part, Best Model, Best Measurement) and specialization tracks (e.g., Best Plant Synthetic Biology, Best Software Tool, Best Sustainable Development Impact), promoting both foundational and applied innovations. Other notable categories include Best Education for outreach efforts fostering dialogue in synthetic biology, Best Integrated Human Practices for incorporating stakeholder feedback throughout the project lifecycle, Best Inclusivity Award for addressing barriers faced by underrepresented groups in STEM, Best Presentation for engaging video summaries, and Best Wiki for clear, navigable documentation. Additional prizes recognize entrepreneurship through viable business plans, hardware innovations with user testing, safety and security practices, and part collections as coherent systems of compatible components. All village teams are eligible for most prizes, except software and AI-focused teams for the Software Tool category, which requires open-source licensing and hosting on iGEM's GitLab.[26][41] Nominations for special prizes occur through judge ballots, where up to three teams per category advance as finalists based on scores in relevant rubrics, with winners selected from these nominees to ensure broad recognition across divisions. The Grand Prize, including the BioBrick Trophy, is awarded to top-performing teams in each division—High School, Undergraduate, and Overgraduate—evaluating overall project quality, presentation, and wiki effectiveness, often aligning with "Best" designations for division leaders.[26] In 2025, iGEM introduced innovations in awards for the newly launched High School division, including a dedicated Grand Prize and Village Awards to celebrate top high school teams alongside collegiate counterparts, emphasizing accessible synthetic biology education and experimentation with white-listed organisms. The Part Collection prize was also updated to require documentation in the iGEM Registry, facilitating community reuse of multi-part systems. Numerous special prizes, including three winners per category across divisions, were distributed, reflecting the competition's scale with 421 teams.[26][42]Participation and Results
