My research interests encompass theoretical and numerical
quantum many-body physics, with a particular emphasis on correlated electrons
and frustrated magnetism. My recent research primarily centers on first principle study of superconductivity with quantum field theoretical approach and modern
numerical techniques.
I have published several papers total google scholar
