After years of building AI models to decode the language of cells, I’m thrilled to announce my next chapter: I will join Xaira Therapeutics as SVP and Head of Biomedical AI. Xaira’s vision is bold—and deeply aligned with my own: to build a virtual cell powered by AI, capable of unraveling the molecular basis of disease and matching the right therapy to the right patient. This is more than just drug discovery—it’s an opportunity to fundamentally rethink how we understand and treat human disease, from first principles to real-world cures. With a $1B+ war chest, an all-star team, and the long view in mind, we’re setting out to do something transformative: create foundation models that can reason over biology and bring precision and speed to every step of therapeutic development. At the same time, I’ll be maintaining my academic affiliations at University of Toronto, UHN, and Vector Institute during the next year to ensure a smooth transition—for my students, collaborators, and the many ongoing projects I deeply care about. Grateful to my mentors, collaborators, students for getting me here. The best is yet to come. Let’s build the future of medicine. #AI #DrugDiscovery #FoundationModels #VirtualCell #Xaira #scGPT #Biomedicine
