The central theme of my research is to understand how mechanical actions feedback to biochemical pathways in cellular processes, and how such mechanochemical crosstalk among key cellular players governs spatial-temporal regulation and shapes cell functions. I confront these challenges by bringing together theoretical and computational studies, rooted in statistical mechanics, with a diversity of biological experiments. My current research interest spans three cellular processes – cell migration, membrane trafficking, and cell division.
