I am a quantitative researcher at a proprietary trading firm in Chicago. I received my Ph.D. in physics at the University of Chicago. During my grad program, my general interest was applying techniques in applied mathematics, computational physics and quantum field theories in problems in many-body physics, including topological phases of matter, quantum Hall physics, and general strongly correlated systems.

Topological Excitations in Solid States
Exotic topological excitations in solid state systems have drawn tremendous attention in the condensed matter physics community in the past 2 decades. In some previous studies, we looked at their existences in some types of spintronic devices.
Collective Excitations in Relativistic Superfluids
Collective excitations help us understand the hydrodynamical fluctuations and possible symmetry breaking patterns in the interested models. In particular in 2 dimensions, collective excitations of superfluid may entail some information beyond topology of topological systems, such as Pfaffian states in quantum Hall systems.
Self-Dual Quantum Electrodynamics
Reliable analytical results are lacking for many low dimensional quantum field theories owing to their strongly-correlated nature. Studying those which are equipped with self-dualities allows us to compute response functions in a trackable manner.
Bosonic Quantum Hall Physics and Dirac Composite Fermions
Owing to the lack of solid state realisation, the study of bosonic quantum Hall states has not been as appealing as its fermionic counterpart. However, recent progress in rotating BEC provides another platform. Theoretically, using relativistic bosonization, it is possible to understand such exotic states using a semi-classical fermionic picture.
