Who we are
The group’s research focuses on understanding how biological systems operate using approaches from theoretical physics. We use statistical physics to understand the structure and function of biological membranes, which experiments have shown operate close to a demixing critical point in the Ising universality class. We also use tools from information theory to place physical bounds on the ability of organisms to function that arise from their limited ability to measure their environment and from their limited energy budget.
