Our Research

One of the long term goals of our group is to resolve the biophysical mechanisms by which cells sense and respond to mechanical stimuli .

A second goal of our group is to characterize the biophysical mechanisms for the onset and spread of neurodegenerative diseases.

Our group also develops new technologies to image and manipulate biological molecules with ultra-high resolution.

Sanjeevi Sivasankar knows a lot about how the healthy cells in your body stick together. He and his research team have studied cell adhesion proteins called cadherins. They’ve developed an instrument that takes 3-D measurements for single-molecule studies of cell adhesion. And they’ve discovered three types of bonds (ideal, catch and slip) by studying cadherins when they’re subjected to a pulling force. - Read complete press release -
