Celebrating the Creative Scientific Life of Ken Jacobson

Our friend and colleague Kenneth Jacobson passed away on February 7, 2022. With Ken's passing, we lost both a leading light in biophysics and a force for collegiality and understanding. Ken is perhaps best known for his development of fluorescence recovery after photobleaching (FRAP, which he used for his email address and license plate!) but also left groundbreaking contributions in membrane biophysics, cytoskeletal dynamics, cell motility, and the use of computational modeling to understand cellular events.
