Prior to joining Illinois Tech, he was an Assistant Professor in the State University of New York (SUNY) at Albany, and received his Ph.D. degree from Rutgers, the State University of New Jersey. His research interests primarily lie in the fields of privacy, security, optimization and data analytics. As such, he is very interested in resolving the security and privacy issues in both fundamental problems (e.g., optimization models) and data intensive systems (e.g., the smart grid, web search, intelligent transportation systems, and data mining). His work has been supported by the NSF.
