Matthew Pamenter, Ph.D.

Associate Professor of Biology

Matt received his Ph.D. from the University of Toronto (2003-2008), where he studied neural mechanisms of anoxia-tolerance in turtle brain in the Buck lab. He then travelled to California to undertake a postdoctoral fellowship in the Haddad lab at UCSD (2008-2012), where he studied mechanisms of ischemic cell death in mammalian stroke models. In 2012, Matt began a second postdoctoral fellowship, split between the Powell lab at UCSD and the Milsom lab at UBC (2012-2015), studying neural plasticity in the hypoxic ventilatory response of rodents, including the naked mole rat.

Matt is broadly interested in how hypoxia-tolerant animals have evolved to survive in low-oxygen environments. His primary focus is on the underlying neural mechanisms of hypoxia-tolerance, with a specific interest in how brain cells survive with little to no oxygen and how neural networks control physiological responses to hypoxia.
