I am the I.I. Rabi Professor of Physics in the Department of Physics at Columbia University. My research is supported by Columbia’s Nevis Laboratories , and funding from the Office of Nuclear Physics in the U.S. Department of Energy. 

I study high energy nuclear collisions (aka relativistic heavy ion physics) to investigate strongly interacting nuclear matter at high temperatures and densities. My research is conducted at the Relativistic Heavy Ion Collider (RHIC), located at Brookhaven National Laboratory. 

I truly enjoying teaching, not only because it’s a real pleasure helping students understand physics but also because the deep questions asked by interested students help me better understand physics. Most recently I have taught our two-semester Quantum Mechanics I and II sequence (GU4021/GU4021). A few years ago I initiated a new course String Theory for Undergraduates (GU4012), a one-semester course covering Part 1 of Barton Zwiebach’s superb A First Course in String Theory.
