Bio Statement

Nanoscale dynamics of cell surface signaling:

Research in the Sheets Group focuses on understanding quantitatively how critical molecular events in a variety of essential membrane-involved processes control biological function. Specifically, we study immunoglobulin E (IgE) receptor signaling, which initiates the allergic response in mast cells. We are developing new quantitative tools, particularly those exploiting fluorescence, to probe spatial and temporal dynamics of the molecular interactions involved in immunoreceptor signaling. Our multidisciplinary laboratory uses state-of-the-art fluorescence microscopy and spectroscopy, optical trapping and nanotechnology to manipulate and interrogate single molecules in living cells and biomimetic systems. Questions we are investigating range from the physical chemistry of functional interfacial lipid-lipid and lipid-protein interactions to the initiation of signal transduction and exocytosis.
