I am a Principal Research Scientist at Visa Research, Palo Alto, California since May 2016. Before that, I spent two years as a Senior Research Scientist at Yahoo Labs! I received my Ph.D. from UC Davis, in 2009, and subsequently spent 5 years in the Department of Computer Science at University of Calgary where I held an Associate Professor position until May 2016. I have been a visiting researcher or an intern at a number of places such as Microsoft Research, Redmond (July 2014, August 2011, October 2010), Sun Microsystems (Summer 2008), Google Inc. (Summer 2007), and UCLA’s IPAM (Fall 2006). My research interests are in information security, cryptography, and privacy enhancing technologies.
