I recently completed my Ph.D. in computer science at UC Berkeley. At Cal, I had the distinction of working with David Wagner on research pertaining to the security of voting systems, and to computer security more broadly. My dissertation, entitled Enabling More Meaningful Post-Election Investigations, examines the state of current election systems and practices, and proposes mechanisms for improving the transparency, reliability, and security of these systems going forward.
