Research Interests


Theoretical and Biophysical Chemistry. The Lin group aims to elucidate the structures and functions of biomolecules by integrating the power of advanced computations with the elegance of chemical theory. Our focus is to develop and apply computational methodology to significant biological problems that are difficult to address experimentally. To ensure that our simulation results are trustworthy, we leverage the tools of theoretical and experimental spectroscopy to integrate selected experimental results with our advanced simulations. This integration enables us to experimentally optimize our new theoretical methods. Optimized simulations are then applied to make predictions and understand biological problems in ways that are difficult or impossible to achieve experimentally. Two major research projects in the Lin lab are (1) to elucidate the structural and functional roles of post-translational modifications on protein folding and (2) to understand the underlying molecular mechanisms of how proteins manipulate their aqueous environment. In both projects, we employ state-of-the-art simulation techniques — parallel computing and graphics processing units simulations – combined with advanced chemical theory (e.g. Markov state models, theoretical vibrational spectroscopy, and normal mode analysis) to provide direct links to experimental results — for example, from infrared and terahertz spectroscopy.
