I am an experimental condensed matter physicist. My research targets development of novel quantum materials that propel the fundamental understanding on emergent phenomena and deliver innovative concepts/routes for nanotechnologies. A major focus is correlated electronic materials such as transition metal oxides (TMOs), which exhibit a variety of unusual quantum phenomena that often elude conventional predictions as well as afford unparalleled functionalities. Moreover, I create interfaces between materials with distinct ground states by oxide-based heteroepitaxy in order to twist their properties and discover new phases in ways that are unavailable in solid state chemistry. This atomically controlled synthesis is synergistically coupled with advanced synchrotron-based characterizations to comprehend the underlying correlated physics and facilitate quantum materials-by-design. My research covers systems that display metal-insulator transition, high-temperature superconductivity, colossal magnetoresistance, orbital ordering/reconstruction, strong spin-orbit coupling, quantum magnetism, multiferroics, as well as magnetic switching.
