Why you should listen
Sarah Bergbreiter runs the Maryland Microrobotics Laboratory at the University of Maryland, where she develops innovative technologies that could advance medicine, consumer electronics and other sciences. She joined the university in 2008 as an assistant professor of mechanical engineering.
Having received her B.S.E degree in electrical engineering from Princeton, she worked on her M.S. and Ph.D. at Berkeley, which is where she focused on microrobotics. She has received multiple awards for her work, including the DARPA Young Faculty Award in 2008 and the Presidential Early Career Award for Scientists in 2013.
