Dr. Nakamura received his M.D. degree from the Jiangxi Medical University of China in 1984 and his Ph.D. from the Tokyo Medical and Dental University of Japan in 1995. Before coming to Murray State University, Dr. Nakamura held a Postdoctoral Research Assistants appointment in the Department of Medicine at the University of Cincinnati Medical Center and a Research Assistant Professor’s position in the Department of Medicine at the University of Florida Medical Center. He has received the Outstanding Young Faculty Award from the American Federation for Medical Research Southern Section and was a finalist in the Hypertension Research Clinical Award given by the American Heart Association.

Dr. Nakamura’s research is focused on the physiological studies of acid-base balance and ion transports in the kidney. His studies include the characterization of the signal transduction pathway involved in stimulation of a potassium-dependent acid secretion transporter (H+-K+-ATPase) and a potassium-independent acid secretion transporter (H+-ATPase) in response to changes in many animal models, such as diabetes and hypertension. Recently, his laboratory demonstrated an essential link between these acid secretion transporters and the glycolysis metabolic pathway. This link may be crucial in understanding the pathophysiological mechanism of diabetes and the metabolism of cancer cells, and the ability of cells to survive during an interruption in blood flow. The majority of his laboratory research utilizes in vitro microperfusion of isolated single kidney tubule in animal models that include transgenic mice. Advanced techniques used in Dr. Nakamura’s laboratory include fluorescent ratio imaging, imaging analysis, cell membrane potential, and bicarbonate or ammonia flux measurements. Undergraduate and graduate students working in this laboratory will have an opportunity to apply many advanced methods in physiology, biochemistry, and recombinant DNA to understanding cellular regulation and molecular cell biology.
