Theoretical and computational research of polymers in materials and biophysics
We develop molecular theories of polymer structure and dynamics in various systems, including: polymer membranes, liquid-liquid phase transitions, elastomers, and bio-polymer networks.
We seek to understand the molecular mechanisms responsible for polymer behavior and corroborate them using molecular dynamics simulations.
