The Freed Group researches several modeling areas, including polymer physics, glass formation in polymers, protein folding, equilibrium self-assembly, and implicit solvent models. We study the influence of monomer molecular structures and interactions on the thermodynamic properties of polymer systems, with special emphasis on glass formation and miscibility. Other projects underway in the group consider theories of the competitive solvation of polymers by mixed solvents, and systems with unusual phase diagrams. Work is progressing on conversion of our protein folding methods to ones using continuous statistical potentials that are applicable to Monte Carlo and molecular dynamics simulations. Several applications of our theory of polarization effects on the properties of charged particles in a dielectric medium are being pursued.
