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.
