Research Interests

Quantum many-body physics. Unconventional superconductivity. Exotic quantum Hall phases of 2D electrons.

My primary interest is to investigate and understand quantum many-body interactions in various physical systems, such as exotic quantum Hall phases of 2D electrons and unconventional topological superconductivity.

At U of Illinois, I have used ultrasensitive phase-locked cantilever magnetometry to investigate the unique magnetic responses of the spin-triplet topological p-wave superconductivity in Sr2RuO4 and, as a postdoctoral fellow at MIT, employed novel pulsed tunneling techniques to study strongly interacting 2D electronic phases in semiconductor heterostructures. From these experiences, I would like to further extend my techniques toward spatially-resolved, quantum-enhanced sensing measurements and apply them to various material systems that exhibit exotic/topological quantum many-body phenomena, including magnetism in quantum materials.
