Moh El-Naggar is an assistant professor of physics at the University of Southern California. El-Naggar received a B.S. degree from Lehigh University (2001), followed by M.S. (2002) and Ph.D. (2007) degrees from the division of engineering and applied science of the California Institute of Technology, where he was an Applied Materials, Inc. fellow. As a biophysicist, El-Naggar is a pioneer in studying energy conversion and charge transmission at the interface between living cells and synthetic surfaces. His work, which has important implications for cell physiology, may lead to the development of new hybrid materials and renewable energy technologies that combine the exquisite biochemical control of nature with the synthetic building blocks of nanotechnology.
El-Naggar was awarded the Presidential Early Career Award for Scientists and Engineers (PECASE) by President Obama in 2013. In 2010, El-Naggar received a prestigious Department of Defense Young Investigator Program (YIP) Award, from the Air Force Office of Scientific Research. In 2012, he was named one of Popular Science's "Brilliant 10", the magazine's annual honor roll of the 10 most promising young scientists whose innovations will change the world. In addition to his research interests, El-Naggar is passionate about STEM education and outreach. He teaches both introductory and advanced graduate physics classes at USC, and enjoys communicating science to the public at all levels, from local community groups to national conferences. At his USC laboratory, he formally advises and mentors graduate, undergraduate, and high school students through interdisciplinary research and education activities linking the physical and biological sciences.
