Who we are

We specialize in measuring and controlling mechanical forces at biological interfaces, ranging from cells to the human sense of touch. These interfaces are complex because they are often soft and patterned. To understand these interfaces, we build devices, conduct experiments, theory, and simulations, and integrate new functional materials. Some of our previous work is shown below.
