and his master’s degree and Ph.D. from the University of California at Los Angeles (UCLA). He went on to do postdoctoral work at UCLA under James Mead, and worked as an assistant research biochemist in the Laboratory of Nuclear Medicine
Nuclear medicine
In nuclear medicine procedures, elemental radionuclides are combined with other elements to form chemical compounds, or else combined with existing pharmaceutical compounds, to form radiopharmaceuticals. These radiopharmaceuticals, once administered to the patient, can localize to specific organs...
and Radiation Biology
Radiobiology
Radiobiology , as a field of clinical and basic medical sciences, originated from Leopold Freund's 1896 demonstration of the therapeutic treatment of a hairy mole using a new type of electromagnetic radiation called x-rays, which was discovered 1 year previously by the German physicist, Wilhelm...

research. Sevanian was promoted from Assistant Professor to Associate Professor and then to full Professor. The institute merged into the Department of Molecular Pharmacology and Toxicology of the School of Pharmacy at USC in the early 1990s, and Sevanian remained there as a Professor of Molecular Pharmacology and Toxicology. He also held an appointment as Professor of Pathology in USC’s Keck School of Medicine. In 1988 Sevanian became a founding member of the Oxygen Society (now the Society for Free Radical Biology & Medicine), later serving as Councillor, Secretary General, and finally Treasurer of the International Society for Free Radical Research (SFRR International). Sevanian died from cancer on Feb. 17, 2005.
Research
Sevanian made major contributions to the understanding of phospholipases as repair enzymes for oxidized membrane lipids. He worked to identify specific oxidative mechanisms in atherosclerosis. He researched the effects of lipid peroxidationLipid peroxidation
Lipid peroxidation refers to the oxidative degradation of lipids. It is the process in which free radicals "steal" electrons from the lipids in cell membranes, resulting in cell damage. This process proceeds by a free radical chain reaction mechanism...
