Dr. Sheena Singh’s interest has been to examine the key renal hemodynamic and metabolic adaptations at the onset of acute and chronic kidney injury, which play an important role in the pathophysiology of disease progression. I have expertise in in-vivo physiological techniques to measure renal hemodynamics, renal micropuncture to assess glomerular and tubular function at a single nephron and whole kidney level, and in-vivo kidney oxygen consumption. I combine these with cellular/molecular biology techniques in mitochondrial bioenergetics, immunostaining and transmission electron microscopy for a comprehensive investigative approach. My research focuses on the coupling of tubular transport and metabolism and novel regulators of these processes such as HIF-1a and AMPK. Current projects include assessment of intrarenal hemodynamics along with determinants of oxygen utilization and mitochondrial function in specific tubular segments in rodent models of acute kidney injury including ischemia reperfusion and cecal ligation and puncture model of sepsis and models of diabetic and non-diabetic chronic kidney disease. These research investigations have been supported in the past by National Kidney Foundation Research awards, pilot and feasibility grant from the NIH funded O’Brien Center for Acute Kidney Injury Research, and NIH K08 Mentored Career Development Award and currently by VA Merit Award (R01 equivalent in the VA research portfolio), NIH R03 award and American Diabetes Association Award.
Include ICU nephrology and acute kidney injury.
