Trisha Nell Davis (born May 27, 1954) is an American biochemist and the former Earl Davie/ZymoGenetics Chair of the department of biochemistry at the University of Washington.[1][2] Her early research focused on Calmodulin, though the primary focus of her lab has since shifted to the molecular machinery of cell division in budding yeast, especially the microtubule organizing centers and the kinetochores. She retired in 2024 after 11 years serving as the Chair.[3]
