My main interest is studying the low-energy theories appearing from intersecting M2/M5 branes in M-theory. M-theory is so rich that it can provide new insights on various topics in physics and mathematics. Especially, the system of multiple M5-branes wrapping on 2 and 3-dimensional manifolds is my current research topic. The topic is closely related to the AGT conjecture, 3d/3d correspondence,holographic principal, quantum Teichmuller theory and volume conjecture.
