Hello! I'm a senior PhD student at Caltech working with Prof. Katie Bouman in the Computing & Mathematical Sciences Department. Previously, I graduated from Princeton University summa cum laude, with a major in Computer Science and minor in Statistics & Machine Learning. I'm interested in computational imaging, in particular incorporating sophisticated priors into ill-posed inverse problems.
