Columbus, OH 43210
Phone: (614) 247-7707

Education
M.S. Novosibirsk State University, Novosibirsk, Russia

Research Interests

Dr. Khramtsov’s research interests include the wide range of Magnetic Resonance applications in chemistry and biology, and studies of free radical processes related to physiological and pathophysiological functions of reactive oxygen (ROS), reactive nitrogen (RNS) and reactive sulfur (RSS) species in various biological systems and models of oxidative stress.

Specific areas of current focus of Dr. Khramtsov’s laboratory:

Functional EPR spectroscopy and imaging, including in vitro and in vivo applications, based on the development of new probes (among them pH-, SH- and NO-sensitive nitroxides)
NMR Spin Trapping technique development and applications, using unique NMR-sensitive traps, to the study of EPR silent chemistry of the radical adducts and ROS detection in biological models of oxidative stress
Studies of redox chemistry of the nitroxides, nitrones and oxidant-sensitive fluorescent probes related to the mechanisms of their reaction with ROS and to their antioxidant properties.

Honors

1987 Award of All-Union Mendeleev Chemical Society (USSR)

1989 Research Fellowship of Alexander von Humboldt Foundation (Germany)

1994 Gold Medal, State Award of Russian Federation in Science and Technology (presented by President of Russia)

1997 Research Fellowship of Fogarty International Center (NIH, USA)

Professional Societies

1990–present International EPR Society

1998–present Society for Free Radical Biology and Medicine (former the Oxygen Society)
