Research
My broad research interests lie at the intersection of the security, privacy, and distributed systems fields. Much of my research focuses on authentication and authorization approaches designed to facilitate secure interactions across organizational boundaries, such as trust negotiation and distributed proof construction. Within this space, I am investigating a number of topics, including protocol design and optimization, privacy-preserving policy evaluation, the incorporation of risk metrics and reputation data into formal proof construction approaches, and efficient techniques for quantitatively analyzing security policies.

Note: Faculty members at the University of Pittsburgh do not individually admit students; admission decisions are made by a central committee. If you are interested in applying to our graduate program, you can find more information here. Unfortunately, I am not always able to respond to e-mail from prospective students, and I apologize in advance.
If you have already been admitted to our CS graduate program and are interested in pursuing a research project with me, please stop by my office or send me e-mail.
