Current Project

Quantum Field Theory

Quarks are always trapped inside color-neutral objects such as protons and neutrons. Why can't the quarks roam the world freely? This is the problem of confinement.

Experimental Particle Physics

Starting in 2024, the LHC will upgrade to 10 times stronger luminosity. Can silicon detectors withstand such high luminosity?

Galactic Dynamics

In the Milky Way, energy and azimuthal angular momentum per star are conserved. But there is a mysterious third conserved quantity. What is it?
