What You'll Do
What if there were an apprenticeship for scientific imagination?
Immersed in our unique company creation process, Fellows start by asking “What if” or “If only.” Working in teams, they use their scientific instincts and creativity to generate novel concepts that go beyond existing scholarship and challenge the dogma of human health, technology, AI, and sustainability.Fellows then learn to iterate, challenge, and shape these ideas into unreasonable yet compelling hypotheses with the potential to produce pioneering new ventures.
As a Flagship Pioneering Fellow you will:
Learn and implement Flagship Pioneering’s unique process of generating and refining actionable, pioneering hypotheses
Exhibit and develop your creativity, adaptability, and ability to innovate in a fast-paced and dynamic environment
Explore ideas and innovations with the potential to become breakthrough companies in industries ranging from human health to sustainability, technology, AI, and beyond

The AI/ML Fellowship Track
Many of the companies Flagship has created over the past 25 years have leveraged advances in computing, big data, and AI. In recent years, this trend has accelerated with first-in-category life science companies such as Generate:Biomedicines, Cellarity, Valo, Apriori Bio, and Lila Sciences.
The AI Fellowship at Flagship Pioneering provides an unrivaled opportunity for individuals to creatively harness computational thinking toward cross-disciplinary innovation as part of our venture creation process. We are looking for extraordinary computational scientists and entrepreneurs to learn our unique company creation process and work alongside entrepreneurs and scientists within the Flagship Ecosystem focused on solving the most impactful challenges in AI and the life sciences. AI/ML Fellows will generate novel venture hypotheses that challenge dogma and have an opportunity to advance these ideas through a hands-on implementation project.
The AI/ML Fellowship track is intended for candidates with deep research and/or industry experience in computational fields such as machine learning, modeling and simulation, computational biology, computational neuroscience, computational chemistry or another discipline with a strong quantitative focus. Proficiency in Python, R, or a similar language and experience building quantitative solutions to challenging problems are required.
