Hello! I am a fifth-year PhD student in the Boston University Department of Computer Science. I am fortunate to be advised by Adam Smith. I'm originally from Ohio, and received a BS in Mathematics from Case Western Reserve University in 2015. My Senior Capstone project was advised by David Gurarie. Before coming to BU, I worked as a data analytics consultant for Mu Sigma.

I do research on the theory of data privacy and machine learning. I want to understand when and why machine learning models memorize large parts of their training data. I also work on differential privacy, and am interested in both creating algorithms for fundamental tasks and proving lower bounds.

I deeply enjoy teaching, both in and out of the classroom. In 2020, I received a Teaching Fellow Excellence Award from the Computer Science Department.
