个人简介

Dr. Naik begin his scientific career earning a Master’s degree in Exercise Physiology from the University of Wisconsin - Milwaukee. This work focused on determining the cellular mechanisms mediating functional hyperemia in skeletal muscle. He continued to pursue his interest in cardiovascular physiology at the University of New Mexico School of Medicine, earning a PhD in Biomedical Sciences where he investigated the signaling pathway mediating vasodilation in response to heme oxygenase-derived carbon monoxide. Dr. Naik completed his postdoctoral training at the University of Mississippi School of Medicine where his research investigated the vascular dysfunction associated with obesity and metabolic syndrome. Dr. Naik joined the UNM SOM Department of Cell Biology and Physiology as a senior research scientist in 2011 and was promoted to the rank of assistant professor in 2017.

个人陈述信

Dr Naik’s focuses on understanding the cellular mechanisms by which endothelial and vascular smooth muscle cells communicate in order to regulated blood flow to meet the metabolic demands of body organs. His most recent work has focused on the role of endothelial-derived gaseous signaling molecules, carbon monoxide and hydrogen sulfide in endothelial-dependent dilation as well as the role of calcium microdomains in ion channel activation. His work was the first to demonstrate that H2S-induced vasodilation involves TRPV4 channels through the formation of Ca2+-sparklets and strengthens our previous observation that a novel endothelial Ca2+-activated large conductance calcium activated K+ channels participate in vasodilation in small mesenteric arteries.
