I am an associate professor in the Computer Science Department at Boston University, and a member of the BU Security Group.
As a network security researcher, my work uses tools from theory (cryptography, game-theory, algorithms) and networking (measurement, modeling, and simulation) to understand the hurdles practitioners face when deploying new security technologies, and to develop solutions that surmount them.
I received my Ph.D.
from Princeton University in 2009, and my B.A.Sc. from the University of Toronto in 2003.
I have worked as a researcher at IBM's crypto group, Cisco Research, and Microsoft Research, New England, as an engineer at Bell Canada and Hydro One Networks, and have served on working groups of the Federal Communications Commission (FCC) and the Internet Engineering Task Force (IETF).
Here's an article and a video about our research group.
I am hiring developers to work on TumbleBit, admitting PhD students, and hiring undergrad researchers!

I am always looking for motivated students and postdocs interested in network security. I have several open positions for spring/summer undergrad or MS interns! See here and please apply!
- I especially enjoy working with motivated undergrads with strong programming skills. Several of my undergrads have won national awards for their research. If you are a BU undergrad and are interested in working with me, please take one of my courses, and drop by my office hours and tell me about yourself. I also welcome students from our M.S. in cybersecurity program.
- If you are a BU grad student are interested working with me or others in the BU Security Group, please enroll in my network security course or in one of the cryptography courses offered by faculty (Canetti, Reyzin) in our group. The best way to get to know us is to join our mailing list and start attending our BUsec seminars.
- If you are interested in graduate study and are not yet at BU, apply to the graduate program in Computer Science at Boston University.
- If you are interested in a postdoc with our group, please email me and describe your qualifications, and type of projects you'd like to work on if you came here.
