With graduate student Bryan Marques, we are comparing the view of protein hydration provided by our reverse micelle encapsulation strategy with that offered by the nitroxide spin radical Overhauser nuclear polarization method pioneered by Professor Han.

With postdoctoral associate Dr. Brian Fuglestad, we are exploring the use of the confined space of the reverse micelle to stabilize the glucocorticoid receptor for structural characterization by NMR.

With postdoctoral associate Dr. Xuejun Yao, we are exploring the evolutionary origins of protein internal motion in ancestrally reconstructed ribonuclease H proteins.

Wolfgang Peti

Professor Wolfgang Peti
Department of Chemistry
Brown University
Providence, RI

With graduate student Kyle Harpole, we are engaged in a multi-PI NIH grant with Professor Peti to explore the role of conformational entropy in small and large ligand interactions with p38α kinase, a major regulatory protein and a high profile target for pharmaceutical intervention.

With graduate student Evan O'Brien and postdoctoral associates Dr. Brian Fuglestad and Dr. Alfredo Caro, we are using molecular dynamics simulations of various systems to gain insight into the microscopic origins of our “entropy meter” based on NMR relaxation methods.
