Jeffrey Tong, Ph.D.


Jeffrey Tong

Jeff uses his extensive operational experience in building and growing early stage biotechnology companies to focus on drug discovery and development across our portfolio. Prior to Third Rock, he was Executive Chairman of Delinia, CEO of Nora Therapeutics, and a member of the founding management team of Infinity Pharmaceuticals. Earlier he worked at McKinsey & Co and was a founding researcher at the Harvard Bauer Center for Genomics Research. Over the course of his career, he has raised significant capital from both equity markets and pharma partnerships, led teams and companies from preclinical through Phase 3 development, and developed integrated science and business strategies for the building of innovative biotechnology companies.

Jeff values that Third Rock at its core is really a company creation firm filled with colleagues who enjoy collaborating with each other to build innovative startups that will discover the medicines of our future. Jeff is professionally at his happiest when he’s working on complex problems that require the integration of science, medicine, business, and strategy.
