Our group develops theory and computational methods to study the behavior of electrons in materials. We use so-called first-principles methods, which can predict the properties of materials by numerically solving the equations of quantum mechanics without any input from experiment. This research provides microscopic insight beyond the reach of experiments, characterizing the interactions and motion of the electrons with ultrashort time and spatial resolutions. One goal is to advance fundamental understanding of electron transport, nonequilibrium dynamics and light-matter interactions in materials ranging from semiconductors to oxides, organic crystals and quantum materials. Another goal is to use this knowledge to study materials and devices electronics, optoelectronics, energy and quantum technologies. Please explore the Research section of this website for more extensive discussions on our work.
