Integrated team of equals
Our leaders in biology, chemistry, protein science, computation, and clinical development made a conscious career choice when they joined Treeline–to be part of an integrated team.
At Treeline, no scientific discipline stands above the others. Since most breakthroughs happen in the open spaces between technical disciplines, we guard against hierarchies and management layers.
We work at multiple locations in the U.S. and Europe. We are united by a shared mission to invent better medicines for patients, reliably and repeatedly.
Meet the Founders
In 2021 co-founders Josh and Jeff joined forces, bringing their complementary skills, networks and passions together to build a new company with an ambitious model. They wanted access to leading-edge technologies and the resources to assemble a complete in-house discovery team. They believed the alternative – outsourced contract research and a one-and-done pipeline – would bring only incremental progress to the diseases they care most about.
Josh and Jeff are both medical oncologists with years of experience leading R&D teams.
Josh Bilenker, M.D.
CEO and Co-Founder
Josh founded Loxo Oncology, which successfully developed three FDA-approved medicines. His earlier roles in venture capital and at the FDA taught him to think backwards from regulatory approval. Generating clinical data worthy of this rare achievement takes careful planning and responsible capital formation.
Jeff Engelman, M.D. Ph.D.
CSO and Co-Founder
Jeff ran an academic research lab at Massachusetts General Hospital before beginning his industry career in large pharma. Jeff is equally at home in the laboratory and the clinic. His understanding of the patient experience enters into every drug design decision he oversees. He loves data, hates cancer and seeks colleagues who care as much as he does.
