Research Interests

My primary research interests are in (embedded) systems security, health IT security, and voting—particularly in voting security and post-election auditing. Beyond those, I am interested in a number of topics such as tech policy—particularly 4th amendment protections against unreasonable searches and seizures as it relates to computers—modern algebra, category theory, cryptography, programming languages, and compilers.

I think research is a social activity and I enjoy collaboration with researchers both inside and outside of JHU.

I am a member of the Johns Hopkins University Information Security Institute (JHUISI) as well as the Center for Automotive Embedded System Security—a collaboration between UC San Diego and the University of Washington. Within JHUISI, I am a faculty member in the Health and Medical Security lab where we work on a wide array of security problems related to healthcare security, as well as other security topics. I am a co-principal investigator of Trustworthy Health and Wellness (THaW), a collaboration between JHU, Dartmouth College, the University of Illinois, and the University of Michigan. I'm always looking for another interesting collaborative project, time permitting.
