About me

I am a doctoral student in Electrical Engineering. My advisors are Bart Preneel and David Chaum.

Research Interests

My research is centered around the topic of privacy enhancing technologies. In particular, I am focused on both attacking and defending anonymous communication systems, exploring the applicability of information-theoretic secure systems for privacy solutions, and designing protocols which satisfy the specific needs of the use case for which they are applied. I have a very strong interest in the real-world applicability of my work; while some of what I do is pure theory, I have always held the believe that if a system cannot be implemented easily or be easily understood by the implementors, its utility is limited. Similarly, I believe that usability is a security concern; systems that do not pay close attention to the human interaction factors involved risk failing to provide security by failing to attract users. Thus, I follow closely the fields of HCI and Applied Programming as well as Information Theory, Cryptography, and Anonymity.
