Simulations of Soft Matter

Group Leader: Prof Halim Kusumaatmaja

Welcome to the Kusumaatmaja group based in the Department of Physics at Durham! We are interested in Theoretical and Computational Soft Matter and Biophysics. Our work is interdisciplinary, lying at the interface between Physics, Chemistry, Engineering, and Biology. Please see our research summary and publications if you want to learn more about our work.
