Vincent Hilser is a professor and chair of the Department of Biology. He received his PhD from Johns Hopkins University and his research focuses on conformational fluctuations and intrinsic disorder in allosteric signaling, disease, and evolution.
Conformational fluctuations have emerged as an important aspect of biological function, playing a critical role in processes ranging from molecular recognition to catalysis and allosteric coupling. Our lab is interested in elucidating the structural and energetic basis of fluctuations, as well as their functional consequences, and applying this information to the development of protein design and optimization strategies and novel fold classification and genomic approaches.
Research in our lab focuses on the development and testing of structure-based models of conformational fluctuations that can capture a broad spectrum of biophysical and functional phenomena within a unified framework. Our goal is to quantitatively link fluctuations to folding and stability, allowing us to investigate the complex interplay between ligand binding, global structural transitions and fluctuations. To challenge and refine our evolving model, we employ a number of experimental systems, using titration and scanning calorimetry, NMR spectroscopy, X-ray crystallography, CD, and fluorescence spectroscopy to provide both global and sight resolved characterizations of proteins.
