I am a fourth year PhD student in theoretical computer science at Carnegie Mellon University, where I am fortunate to be advised by David Woodruff. I graduated with a B.Sc. from Brown University in May of 2017, where I concentrated in mathematics and computer science.
My research interests are primarily in sublinear algorithms, especially sketching and streaming algorithms for problems in big-data. In general, I like to think about problems regarding dimensionality reduction; namely, to what extent can we compress the significant components of an enormous, noisy data-set? A common theme of my work is applying sketching techniques to database systems and statistical inference tasks. Additionally, I am interested in property testing, machine learning, and optimization.
