Dr. Nikolai V. Gorbunov received a Ph.D. in Biology from the Russian Academy of Sciences. He was granted a postdoctoral research award by the NRC Research Associateship Programs, after which he joined the Walter Reed Army Institute of Research (WRAIR), Maryland, USA, to pursue postdoctoral training and research on biophysics and molecular and cellular pathology of blast-related polytrauma. Dr. Gorbunov completed a DoE-sponsored training in radiation sciences and radiation health at the University of Pittsburgh and the Pacific Northwest National Laboratory, Washington, USA (www.emsl.pnl.gov/emslweb). His translational research areas include redox homeostasis, cellular mechanisms of barrier functions in conjunction with the biology of blast polytrauma, and acute radiation illness. In this framework, he investigated molecular and cellular mechanisms leading to vascular dysfunction and impairment of tissue barriers in the pathogenesis of radiation-combined injury with a focus on the development of new remedies for the management of the diseases. He conducted this research at WRAIR and the Uniformed Services University of the Health Sciences, Maryland, USA (https://www.usuhs.edu).
