Wesleyan will host the 13th annual Molecular Biophysics and Biological Chemistry Retreat Sept. 27. The public is invited. Bertrand García-Moreno, professor and chair of the Department of Biophysics at John Hopkins University will deliver the keynote lecture at 4:15 p.m. He will speak on "Molecular Determinants of Electrostatic Effects in Proteins." García-Moreno investigates the relationships between protein structure, function, energetics, and dynamics with an emphasis on electrostatic properties that govern the actions of proteins in all biological processes. His research on ionizable groups buried in the hydrophobic interior of proteins provides fundamental insights into their special chemical properties and critical…
