Four University of Pittsburgh professors have been named fellows of the American Association for the Advancement of Science for accomplishments in their fields. Honored are Bruce Freeman, Peyman Givi, Valerian Kagan and Allan Sampson.
They are among 702 fellows selected this year by AAAS, the world's largest general scientific society.
Bruce A. Freeman, professor and chair in the School of Medicine's department of pharmacology, is honored for work in free radical biology and the regulation of cell function. His research focuses on the biochemical links between oxygen radicals; his team pioneered a new understanding of nitric oxide in its critical roles in inflammation and cell regulation.
Peyman Givi -- professor in both the Swanson School of Engineering's department of chemical and petroleum engineering and its department of mechanical engineering and materials science -- was honored for contributions in computational combustion and for his dedication to teaching and the engineering profession. His research aims to create more fuel-efficient engine designs.
Valerian Kagan, professor and vice chair in the Graduate School of Public Health's department of environmental and occupational health, was honored for his work in free radical biology, medicine and programmed cell death. He is also the director of Pitt's Center for Free Radical and Antioxidant Health, as well as professor of pharmacology and chemical biology, radiation oncology and chemistry. His research is focused on molecular mechanisms of oxidative stress, antioxidants, tissue and cell acute and chronic injury, and molecular and nanotoxicology.
Allan R. Sampson, professor of statistics in the Kenneth P. Dietrich School of Arts and Sciences, was honored for work in statistical methodology, advancing innovative statistical techniques in neuroscience and clinical trials, and fostering the studying and teaching of statistics.
