Biography

Dr. Marchant received his PhD in Pharmacology from the University of Cambridge in the laboratory of Colin Taylor, and then performed post-doctoral training as a Wellcome Trust Training Fellow in Ian Parker’s laboratory in the Department of Neurobiology and Behavior at the University of California-Irvine. He was a Faculty Member in the Department of Pharmacology at the University of Minnesota from 2002-2017, until joining MCW as the Marcus Chair of Cell Biology, Neurobiology and Anatomy in 2017.

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.

NAADP-binding proteins find their identity.
