Modeling Biomolecular Systems
The Zuckerman group develops and applies computer simulation methods for studying biological systems. A primary focus is the deployment of sampling algorithms based on statistical physics that can be used to study (i) large-scale, potentially allosteric motions in proteins, (ii) signaling processes encoded in interaction networks, (iii) protein binding, and (iv) protein folding. Among the strategies used in the group are approaches that can yield super-linear parallel performance – estimation of observables using N processors that is more than N times faster than an estimate based on a single-processor simulation. Prof. Zuckerman also has a strong interest in biophysics education, which has led to a textbook and a new online book.
