Computer Security and Applied Cryptography
Charalampos (Babis) Papamanthou is an Assistant Professor in the Department of Electrical and Computer Engineering at the University of Maryland, College Park, where he also holds an affiliate position at UMIACS and he is a member of the Maryland Cybesecurity center (MC2). Before joining UMD, he was a postdoctoral researcher at UC Berkeley, working on the areas of applied cryptography and computer security---and especially on technologies, systems and theory for secure and private cloud computing. He obtained his PhD and MSc in Computer Science from Brown University in 2007 and 2011 respectively. While at Brown, he was the recipient of the Kanellakis and van Dam fellowships and he also interned at Intel Research (2008) and Microsoft Research (2010). Before graduate school, he studied in Greece at the University of Crete (MSc) and the University of Macedonia (BSc). He has published in venues and journals spanning theoretical and applied cryptography, systems and database security, graph algorithms and visualization and operations research.
