About me
Hello! My name is Jennifer Sun, and I am a Ph.D. candidate at the Department of Operations Research and Financial Engineering at Princeton University, advised by Prof. Elad Hazan from the Department of Computer Science. I am generously awarded with the Gordon Wu Fellowship. I am broadly interested in machine learning theory, and my recent work particularly focuses on online learning and its intersection with optimization and nonstochastic control theory.
During my time at Princeton, I also worked as a student researcher for the algorithmic efficiency team with Vlad Feinberg at Google DeepMind, working on memory efficient optimization algorithms. Before coming to Princeton, I graduated Summa Cum Laude and Phi Beta Kappa from The University of Chicago with a Bachelor of Science degree in Mathematics with honors.
I was born and raised in Shanghai, China. I moved to Pebble Beach, CA to attend Stevenson School at the age of 15. Those four years have been the most precious time in my life.
