Summary of Research

The cell membrane plays a crucial role as a selective barrier for the movement of nutrients, chemical signals, and metabolites between the cytoplasm and the cell's exterior environment. The transport of such chemicals, and consequently membrane behavior, is essential to the normal functioning of the cell and the overall survival of the organism. We know how the cell membrane behaves in a variety of important biological processes, but in most cases do not understand the underlying physics. My research focuses on using a variety of techniques from statistical mechanics, continuum mechanics, and finite element methods to develop models that better explains cell membrane behavior.
