Dr. Parikh received his medical degree from Seth G.S. Medical College and KEM Hospital in Mumbai, India and subsequently completed his Nephrology fellowship and a PhD in Clinical Investigation at the University of Colorado Health Sciences Center. Dr. Parikh’s research focuses on the translation and validation of novel biomarkers for the diagnosis and prognosis of acute kidney injury. Progress in kidney diseases has been hamstrung by significant heterogeneity within the current disease definitions, which are largely based on serum creatinine. Dr. Parikh’s research has addressed this critical challenge by developing biomarkers of renal tubular injury, repair, and inflammation to dissect this heterogeneity. He has assembled multicenter longitudinal prospective cohorts for translational research studies across several clinical settings of acute kidney injury and chronic kidney disease for the efficient translation of novel biomarkers. His research is dedicated to the process of applying discoveries generated in the laboratory and in preclinical experiments, the development of clinical studies, and the design of clinical trials. Dr. Parikh’s studies have refined the clinical definition in perioperative acute kidney injury and hepatorenal syndrome, developed strategies to reduce kidney discard in deceased donor transplantation, and advanced regulatory approvals of kidney injury biomarkers. He has also developed biomarkers to identify rapid progressors of early diabetic kidney disease before derangements in serum creatinine. Dr. Parikh’s research goal is to translate our understanding of pathophysiological mechanisms into clinical practice and improve the outcomes in patients with kidney disease. Dr. Parikh has also been the recipient of numerous honors, including the 2017 Young Investigator Award from the American Society of Nephrology.
