Joel Barrish
Joel Barrish is the President and CEO of Avilar Therapeutics, a Waltham, Massachusetts-based biotechnology company pioneering extracellular protein degradation. A medicinal chemist by training with a Ph.D. from Columbia University, Barrish spent 28 years at Bristol Myers Squibb rising to VP and Global Head of Discovery Chemistry, co-inventing blockbuster drugs including SPRYCEL (dasatinib) for leukemia. After stints as CSO at Achillion Pharmaceuticals and co-founder/President at Jnana Therapeutics, he founded Avilar in 2019 to build the ATAC and MTAC platforms - bifunctional molecules that hijack the body's own cellular recycling machinery to degrade disease-causing proteins outside the cell, a class of targets previously undruggable. Avilar has raised $75 million in total seed financing.
