I am an assistant professor in the Department of Computer Science at University of Calgary. My research interests are in information security, cryptography, and privacy enhancing technologies. I am also a member of the Institute for Security, Privacy and Information Security (ISPIA) at U of C. I received my Ph.D. from UC Davis, in 2009 under the supervision of Matthew Franklin. I have been a visiting researcher or an intern at a number of places such as Microsoft Research, Redmond (August 2011, October 2010), Sun Microsystems (Summer 2008), Google Inc. (Summer 2007), and UCLA's IPAM (Fall 2006).

I am looking for new graduate students. In case of PhD students, I almost strictly require previous experience in cryptography, and an interest in both theoretical and practical aspects of the field. Please take a look at my research interests, and publications to determine if your research experience and interest has some overlap with mine. After doing so, feel free to contact me to. Make sure to include a CV, your TOEFL/IELTS score (for international students), and an unofficial copy of your transcripts.
In general, if you are interested in working with me, you need to put my name in your application form. Otherwise, it is likely that I won't get to see your application. You can find all the necessary information related to the admission process here.
University of Calgary undergraduate students who are interested in getting involved with research related to cryptography and/or information security are encouraged to contact me for more information. Also see here and here for detailed information on how to earn credit for doing undergraduate research.
