My Research

In the Weiner Lab, I use light-controlled recruitment of key signaling proteins in cell migration to better understand how rapidly-migrating cells make "decisions" about their movement. Some of the simplest challenges that they need to overcome are maintaining a single axis of direction (it's not efficient to try to move in two directions at once) and dynamically aligning that axis to (possibly weak or noisy) external cues. Using spatially patterned light, we can ask novel questions about how cells interpret spatial and temporal patterns of these key signaling molecules.
