Research Interests

Privacy-by-default systems design using confidential computing and applied cryptography.

About

I am a PhD candidate in Computer Science at William & Mary, specializing in systems security. I work with Prof. Stephen Herwig in the Extending Trust in Computing Lab (etclab). My research focuses on building systems that embed privacy guarantees by design, using confidential computing, applied cryptography, and distributed and networked systems to make privacy the default rather than an opt-in feature.
