Overview

The overarching research theme of the group is to develop a fundamental understanding of important biological polymers and assemblies, and to develop engineering solutions for an improved healthcare. We are interested in employing multiscale modeling and simulation tools, systematic coarse-graining strategies and enhanced sampling techniques to enable designing of nanopores for accurate diagnosis of diseases, identifying of novel drug targets and improving drugs and drug-carriers for treating diseases.
