Samouil Farhi is a group leader at the Klarman Cell Observatory at the Broad Institute of MIT and Harvard, where he leads the Optical Profiling Platform. He joined the Broad Institute in July 2018 after completing his Ph.D. in chemical biology at Harvard University with Adam Cohen, where he developed methods for all-optical investigations of neuronal systems. The platform’s goal is to bring next-generation imaging approaches to bear on large-scale biological problems, with a focus on profiling the spatial organization of tissues, high-content phenotypic screens and all-optical studies of the electrical properties of cells.
