Welcome Image


We are a group of biophysicists, cell biologists and computational folks interested in the spatiotemporal organization of cell surface receptors, the mechanisms underlying it, and its consequences for cell signaling. We utilize light microscopy, particularly single-molecule and super-resolution imaging, to monitor molecular behavior in its native cellular environment, and we develop computer vision and mathematical modeling approaches to quantitate the observed behavior and gain insight beyond what the eye can see.
