Full CV

Dr. Prabha Nagareddy obtained his B. Pharm and M. Pharm degrees from Bangalore University (1998) and RGUHS (2001) respectively from Bangalore, India. He then spent a year working as a pharmacologist in a pharmaceutical company before moving to Canada. In the fall of 2002, he joined the laboratory of Dr. John McNeill at the University of British Columbia and received his MSc (2004) and PhD (2009) degrees. Since his graduate training, Dr. Nagareddy is interested in understanding the molecular pathways that contribute to accelerated cardiovascular disease in diabetes. His MSc thesis research was primarily focused on studying the aberrant signaling mechanisms in blood vessels that contributed to impaired endothelial function, attenuated pressor responses to vasoactive agents and depressed blood pressure in animal models of type I diabetes. His doctoral research was aimed at understanding the mechanisms of insulin resistant hypertension in type 2 diabetes. He specifically studied the role of matrix metalloproteinase (MMPs) and the MMP-dependent epidermal growth factor receptor transactivation pathway in the development of insulin-resistant hypertension. During the entire time of his graduate research he was supported by funding from the Heart and Stroke Foundation of Canada and Michael Smith Foundation for Health Research.

Upon completing his PhD, Dr. Nagareddy moved to New York to commence a postdoctoral fellowship with Dr. Ira Goldberg at Columbia University. During this time, he was funded by a prestigious Canadian Institute of Health Research Fellowship. At Columbia, his postdoctoral work broadly focused on two main themes; mechanisms of accelerated atherosclerosis in diabetes and identification of the origins of adipose tissue macrophages in type 2 diabetes/ obesity. In collaborations with Drs. Alan Tall, Andrew Murphy and Ed Fisher, he discovered a novel role for the damage associated molecular patterns S100A8/A9 in hyperglycemia-accelerated atherosclerosis in diabetes. These findings which were published in the journal Cell Metabolism in 2013 laid the foundation for his future research work and a long-standing collaboration with Dr. Andrew Murphy at Baker IDI Heart and Diabetes Institute in Melbourne, Australia.

In 2013, Dr. Nagareddy joined the laboratory of Dr. Susan Smyth at the University of Kentucky (UK) and continued to work on exploring the mechanisms of myelopoiesis in obesity and its impact on adipose tissue inflammation, insulin resistance and cardiovascular disease. This work which also was the basis of his successful K99/R00 grant application specifically targeted the pathways that regulate myelopoiesis in the bone marrow (sterile inflammation). The findings from these studies were published once again in Cell Metabolism (2014) accompanied by editorials and cover page highlights. Lately in collaboration with Dr. Abdel-Latif, an interventional cardiologist at the UK and Andrew Murphy at Baker, he is studying the mechanisms of neutrophilia in conditions of acute myocardial ischemia. Further, in collaboration with his wife Dr. Beatriz Hanaoka, a Rheumatologist at UAB, he is exploring the molecular pathways that contribute to increased cardiovascular disease risk in Rheumatoid Arthritis (RA) patients.

In the May of 2016, he was recruited as an Assistant Professor by the Department of Nutrition Sciences at The University of Alabama at Birmingham. With these training experiences, he has expanded his research in exploring similar pathways that promote/mediate sterile inflammation in different disease settings such as acute myocardial ischemia, traumatic brain injury, stroke, rheumatoid arthritis etc.

His outside interests include reading, cooking, travelling and most importantly time with his wife and 2-year-old triplet girls.
