Dr. Kenneth R. Olson is a Professor of Physiology (Emeritus) at Indiana University School of Medicine-South Bend and an Adjunct Professor in the Department of Biological Sciences at the University of Notre Dame. He graduated with a major in Chemistry and Biology from the University of Wisconsin-LaCrosse in 1969, followed by his M.S. and Ph.D. in Physiology from Michigan State University in 1970 and 1972, respectively. His research involves three aspects of H2S biology: (1) the role of H2S in oxygen sensing in the cardiovascular system; (2) H2S production and metabolism in tissues; and (3) the applicability of a variety of newly developed H2S-donating drugs in physiology and medicine.
