Jen Dionne received her Ph.D. in applied physics in 2009 at the California Institute of Technology. After a postdoctoral research fellowship at the University of California, Berkeley, and Lawrence Berkeley National Laboratory, she arrived at Stanford University, where she is now an assistant professor of materials science and engineering. Her research investigates metamaterials—engineered materials with optical and electrical properties not found in nature—for applications ranging from high-efficiency solar energy conversion to bioimaging. In 2011, she was named one of Technology Review’s TR35—35 international innovators under 35 tackling important problems in transformative ways. She has also received the NSF CAREER Award (2012) and an AFOSR Young Investigator Award (2011).
