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.
Joanne Kotz
Joanne Kotz is a chemist-turned-biotech-CEO who runs Atalanta Therapeutics, a Boston company using divalent siRNA to silence disease-causing genes throughout the brain and spinal cord. She took the top job in June 2025 after co-founding and leading Jnana Therapeutics from a blank slate to a roughly $1 billion acquisition by Otsuka. Before founding companies she helped build them from the science up, as a director at the Broad Institute, a leader of F-Prime's neurodegeneration initiative, and the founding editor of Nature Chemical Biology. Her career runs an unusual loop: bench scientist, science journal editor, partnership architect, founder, and now CEO of a company chasing some of the hardest diseases in the central nervous system.
