Riggleman Computational Soft Matter Lab
The Riggleman Lab at the University of Pennsylvania develops and implements advanced molecular modeling techniques to study soft matter systems like polymers and glassy materials. We explore the dynamics and thermodynamics of these systems across a variety of time and length scales to help explain and predict experimental findings.
