Research Interests

Developing and applying biophysical (particularly electrical and optical) techniques toward the understanding of the dynamics of cell secretion from individual cells

Research Description

My main area of interest is understanding the final steps of cell secretion and the modulation of these steps by calcium and second messengers. We use multiple biophysical approaches to assay dynamic aspects of secretion from individual adrenal chromaffin cells. Since calcium and second messengers play a central role in regulating both secretion of hormones and release of neurotransmitter at synapses, the results of our research have an impact on understanding such diverse phenomena as the "fight or flight" response and the formation of short-term memory.

Our research also has a strong engineering component with particular emphasis on developing or refining electrical and optical techniques for studying secretion. In particular, we have been developing microchips with arrays of transparent electrochemical electrodes to measure secretion of catecholamines from individual cells simultaneously with optical measurements.  Other techniques in use in the lab include patch-clamp electrophysiology with membrane capacitance measurements as an assay of exocytosis/ endocytosis, photometric measurement of the intracellular Ca2+ concentration with indicator dyes, and photo- release of intracellular Ca2+ from caged compounds.
