I am interested in nonequilibrium open quantum systems, namely, quantum systems which are interacting with the environment, being measured, or under manipulation. My current research aims at developing effective models to quantitatively study the rich phenomenology (e.g., decoherence and collective modes) emerging from the interaction between quantum systems and various mesoscopic environments. In particular, I focus on quantum optical systems in the context of circuit QED, where recent experimental developments call for the development of better theoretical frameworks to quantitatively explain the rich physics of open quantum systems that are nonlinear or out-of-equilibrium. I completed my undergraduate program in physics at Caltech, where I had a variety of research experience from working with scanning-tunneling microscopes to studying the mathematical properties of gravitational instantons. In my spare time, I enjoy rock-climbing, cooking, and the art of fermentation.
