Research Interests

We are interested in the how cells respond to stimulation. Our focus is on signal transduction through Ca2+ signaling. Indeed, it is hard to think of any cellular process that is not regulated by Ca2+. Ca2+ signals can result from activation of intracellular Ca2+ channels and dysfunction of these same Ca2+ channels are involved in neurodegenerative disease and cancer. To appreciate how cell functions are controlled by Ca2+ signals, and how pathological cues subvert their function, we must understand how the distribution and the regulatory properties of intracellular Ca2+ channels control the genesis of Ca2+ signals.
