Overview:

Multi-scale modeling of complex chemical systems has become crucial for understanding several aspects  of chemistry today. State of art simulation methods have proven to be critical in providing molecular-level insights into biological processes at a level of resolution inaccessible to most experimental techniques. Our group is involved in building a framework for such hierarchical multi-scale models. In particular, we are developing and applying coarse-grain models to drive the understanding of several cellular membrane related phenomenon at biologically-relevant times-scales. The main question we address is "What drives and regulates protein localization/association and membrane topography and can these self-assembled systems be modulated with synthetic mimetics?" Have a look at our research page to know further.
