Biomembranes are fundamental to our understanding of the cell, the basic building block of all life. They provide structure and identity to the cell as a whole and many internal organelles. Biomembranes exhibit diversity in their shapes and complexity in chemical compositions that are linked to many cellular functions. My research focuses on the development and application of computational methods for understanding the lateral and spatial organization of biological membranes. These processes often span a wide range of spatiotemporal scales. Therefore, I am using distinct simulation techniques, e.g., all-atom and coarse-grained molecular dynamics, dissipative particle dynamics, and mesoscopic simulations, and connect them through a specific multi-scale simulation scheme that I have developed.
