Jefte Drijvers

At Third Rock, Jefte focuses on the creation of new companies seeking to apply scientific advances to unmet clinical needs. He enjoys how this allows him to bring together his backgrounds in biomedical science and clinical medicine. Jefte first joined Third Rock as a senior associate in 2020, playing a key role in the formation of Abata Therapeutics, where he later transitioned to leadership roles in program strategy and business development. He returned to Third Rock in 2025 and is focused on advancing early-stage therapeutic concepts into transformative biotech companies.

He previously received his M.D. from Radboud University in the Netherlands and his Ph.D. in Immunology from Harvard University, where he studied the metabolic regulation of T cells in cancer. 

Outside of work, Jefte is an avid runner, cyclist, and hiker—and above all stays active keeping up with his young twins.
