I am a Postdoc Researcher at UC, Riverside. My research focuses on the derivation, development, and implementation of efficient computational methods for condensed matter physics. I am one of the main developers of the VG-rtTDDFTB, ATLAS and ARES packages for large-scale simulations at the DFT level.

Research Interests

My research focuses on the development of novel theoretical and computational method for mesoscale condensed matter physics:

• Orbital-free density functional theory (OFDFT);
• Velocity-gauge real-time time-dependent density fucntional tight-binding (VG-rtTDDFTB);
• Real-space pseudopotential electronic structure calculation package (ARES);
• Core-level binding energies calculation method.
