I am a second year Ph.D student at the University of Utah, where I am advised by Pratik Soni. I am interested in cryptrography, particularly in zero-knowledge proofs (ZKPs) and digital signatures.

My work so far has been focused in two areas: (1) developing efficient techniques for proving digital media provenenace, and (2) creating novel digital signature schemes (e.g, adaptor signatures) that enable fair exchange on blockchain systems.

Previously, I received my B.S. in Computer Science (with an additional major in mathematics) in 2024 from Trinity University, where I was advised by Yu Zhang.

You can find my CV here, and a list of my publications here.
