Ed Boyden is a professor of biological engineering and brain and cognitive sciences at the MIT Media Lab and McGovern Institute. He leads the Synthetic Neurobiology Group, which develops tools for analyzing and repairing complex biological systems such as the brain, and applies them systematically to reveal ground truth principles of biological function as well as to repair these systems. These technologies include expansion microscopy, which enables complex biological systems to be imaged with nanoscale precision, and optogenetic tools, which enable the activation and silencing of neural activity with light. He also co-directs the MIT Center for Neurobiological Engineering. Amongst many recognitions, he has received the Breakthrough Prize in Life Sciences (2016), the Grete Lundbeck Brain Prize (2013), and the NIH Director's Pioneer Award (2013). He has also co-founded numerous biotechnology companies, including Cognito Therapeutics, Expansion Technologies, and others, and serves on numerous scientific advisory boards.
