Matthew Lew, at the McKelvey School of Engineering, is part of a team that received a $7.5 million five-year award under the U.S. Department of Defense’s highly competitive Multidisciplinary University Research Initiative Program (MURI). The team’s research is aimed at developing a new class of functional living electronics based on living materials such as proteins and bacteria.
