I am a second year PhD student in the Electrical Engineering department at Stanford University, interested in randomized algorithms for optimization, advised by Madeleine Udell.

Before Stanford, I graduated from the University of Maryland with a BS in Electrical Engineering and BS in Mathematics. As an undergraduate, I held internships at STR, where I conducted research on radar image processing, and Lockheed Martin, where I reviewed and tested computational models for satellites. I also conducted research in number theory, for which I received the Dan Shanks Award from the University of Maryland Math Department.

I'm interested in using randomization to improve the scalability of optimization algorithms, especially in applications to machine learning. Recently, I've thinking about using sketching and low-rank approximation to develop new optimization algorithms for machine learning tasks.

We use techniques from randomized numerical linear algebra to develop an improved stochastic quasi-Newton method.

We prove new results regarding the prime factorizations of Descartes numbers, a family of odd spoof perfect numbers.
