Qing Guo, MD, PhD
Dr. Guo is Professor of Physiology at the University of Oklahoma Health Sciences Center (OUHSC), College of Medicine. He is also a faculty member in the Physiology and Neuroscience Graduate Programs at OUHSC.
Education and Training:
Dr. Guo received his M.D. degree in medicine in 1984 and Ph.D. in neurobiology in 1993. He pursued postdoctoral research in molecular biology of cell death under Professor Mark P. Mattson in Sanders-Brown Center on Aging at the University of Kentucky before joining the faculty in the Department of Neurobiology and Pharmacology at Northeastern Ohio Universities College of Medicine (NEOUCOM) in 1999. Since 2003, Dr. Guo has been a faculty member in the Department of Physiology at the University of Oklahoma Health Sciences Center.
Resarch Summary: Signaling of Cell Death in Physiology and Disease
Research in Dr. Guo's laboratory centers on some of the fundamental questions in the life and death of cells in a variety of organ systems and diseases, particularly those related to neuronal injury and neurodegeneration. First, we examine how specific genetic mutations and cell death proteins regulate intracellular pathways that control cellular life and death. Secondly, we examine how aberrant regulation of the apoptotic machinery is involved in pathological disease conditions, such as neurodegeneration, brain trauma, and acute renal failure. Our studies involve the application of a variety of gene transfer and targeting protocols, including the generation and characterization of transgenic and/or knockin/knockout mouse models. Dr. Guo has served on NIH study sections and reviews grant applications for national and international funding agencies. He also serves on Editorial Boards of several professional journals and reviews manuscripts on a regular basis.
Teaching and Mentoring:
Dr. Guo's teaching experience began in 1984, and he has taught students of different academic, ethnic and economical backgrounds, with diverse career goals and personal interests. Dr. Guo's lectures and lab sessions covered many topics including those in Medical Neuroscience, Functional Neuroanatomy, Medical Physiology (including respiratory physiology), Medical Problems, Cell Death in Physiology and Disease, Mechanisms of Aging, Reproduction and Women's Health, and Journal Clubs. He was the course director for Integrative Physiology, a core course for graduate students in Graduate Programs in Biomedical Sciences (GPiBS) at OUHSC. He also served as Chair of graduate programs in Physiology at OUHSC. He had the pleasure of mentoring seven PhD students in his lab. Beyond his own laboratory, he served on many PhD dissertation committees, covering campuses of Northeastern Ohio Universities College of Medicine and Pharmacy (NEOUCOM), OUHSC and Oklahoma Medical Research Foundation (OMRF).
