We conduct theoretical research on energy and charge flow dynamics in condensed phase molecular systems ranging from liquids to biological systems. The major focus is on quantitative understanding and description of quantum dynamical effects. This requires integration of theory development, large scale computation, and modeling of complex spectroscopic data. Development or identification of appropriate coarse-grained models and practical quantum dynamics calculation methods are also crucial. The diagram below depicts the general strategy of research.


Our research has significant implications for energy conversion and storage, sensing, and biological imaging. At fundamental level, the research can elucidate important quantum dynamical effects underlying seemingly classical behavior or chemical rate processes.
