Dr. Chelsea Hu, an assistant professor in the Artie McFerrin Department of Chemical Engineering at Texas A&M University and a member of the Accountability, Climate, Equity, and Scholarship (ACES) Faculty Fellows Program, is using synthetic biology to help scientists control genetically engineered cells. Her study is the first to use modeling and a physical experiment to show the effectiveness of layered feedback mechanisms. Hu collaborated with Dr. Richard Murray at the California Institute of Technology.
