I use physical principles at the molecular scale to solve macroscopic problems in biology, e.g. How do a molecule's mechanical properties influence the behavior of a cell? How do single molecule measurements relate to muscle function? To answer such questions, I use a combination of computer simulations and mathematical analysis. This theoretical work is complemented by experiments performed by my collaborators. In my teaching, I enjoy emphasizing connections between math and other disciplines.
The Worcester Business Journal reports on WPI Mathematical Sciences Professor Sam Walcott’s research to develop a mathematical model for muscle movement that could lead to improved medical treatments and the creation of better prosthetic devices.
