I am a CS Ph.D. student at Princeton, advised by Olga Russakovsky. I am generously supported by the GEM Fellowship and President’s Fellowship. I previously studied Math at Stanford where I was fortunate to have been advised by Yoonho Lee, Pranav Rajpurkar, and Christine Taylor. I am interested in mathematical reasoning.
