Geoffrey Duyk, Grove Biopharma CEO, on Polymer Breakthroughs, Intractable Targets & Biotech's Future
Synopsis:
Host Rahul Chaturvedi sits down with Geoffrey Duyk, Chief Executive Officer of Grove Biopharma, for a wide-ranging conversation on navigating today’s biotech macro headwinds and building companies that can translate breakthrough science into real patient impact. Dr. Duyk traces his journey from Harvard/Millennium/Exelixis operator to TPG investor and back to company creation, explaining how board dynamics, capital cycles, and policy shifts shape execution.
They dig into why this cycle feels uniquely tough—patent cliffs, reimbursement uncertainty, NIH pressures—and who funds innovation in the meantime. Duyk outlines root causes of R&D inefficiency (misaligned capital vs. 20-year timelines, shaky preclinical predictability, costly trials, underused real-world data) and makes the case for rebuilding public trust and STEM education.
Then, a deep dive on Grove Biopharma: precision polymer science that creates antibody-like, fully synthetic, cell-permeable protein mimetics to tackle historically “intractable” intracellular protein–protein interactions. Duyk shares design principles, why modular/orthogonal chemistry matters, predictable pharmacology, and lessons from fundraising and board management—plus why he’s helping grow a Chicago-centered biotech ecosystem.
