Liquid Structure

In this interdisciplinary work we are studying multicomponent, aqueous protein mixtures that are important for understanding the cytoplasm of the lens of the eye. A number of mathematical projects are essential for this work including (i) statistical-thermodynamic modeling of the free energy and liquid structure of globular protein mixtures, (ii) the interpretation of light, neutron and X-ray scattering data relevant to liquid structure and thermodynamics, (iii) statistical thermodynamic Monte Carlo and molecular dynamics simulation of concentrated protein mixtures, and (iv) study and modeling of the potentials of mean force between protein molecules.
