Research Interests: 

I am a computational physicist who develops and utilizes advanced simulation techniques to understand quantum materials and devices. My research is interdisciplinary in scope and spreads over condensed matter physics, electrical engineering, material science, and computational science. My objective is to develop future electronics and computing technologies utilizing novel quantum phenomena in condensed matter. Solid-state quantum computing is one of my active areas of research. I have developed computational tools that can model various aspects of semiconductor qubits such as electronic structure, response to electric and magnetic fields, many-body interactions, and spin-lattice and spin-spin interactions. I am also interested in emerging 2D and topological materials for low energy electronics.
