Reza Heidari is a researcher in the Pharmaceutical Sciences Research Center (PSRC), Department of Pharmacology and Toxicology, College of Pharmacy, Shiraz University of Medical Sciences. Until September 2013, he was a Senior Researcher in PSRC. He served as the Vice-Chancellor of Research Affairs of PSRC (2015-present). Dr. Heidari received a Pharm.D degree from College of Pharmacy, Shiraz University of Medical Sciences, and a Ph.D. in Toxicology from the Tabriz University of Medical Sciences. His work is in the areas of mechanistic toxicology, cholestasis/cirrhosis and their associated complications, hepatic encephalopathy and hyperammonemia, hepatotoxicology, drug-induced liver injury (DILI), xenobiotics-induced mitochondrial impairment, and cellular responses to oxidative stress. He has a particular interest in the role of mitochondrial impairment in the pathogenesis of human diseases and xenobiotics-induced mitochondrial dysfunction. His work with the cholestatic/cirrhotic animals demonstrated several cellular and molecular mechanisms for the complications associated with these diseases. These works might lead to finding therapeutic options against these complications. Dr. Heidari received several awards during his working experience, including top researcher in 2017, Shiraz University of Medical Sciences; Top University Researcher, 2019, Shiraz University of Medical Sciences; and Incentive Top Researcher Grade 2019, Shiraz University of Medical Sciences. Reza Heidari is the Associate Topic Editor at Reproductive Toxicity and Xenobiotic-induced Animal Infertility in the journal of Frontiers in Veterinary Science. Dr. Heidari is also a member of the Iran Pharmacists Association (2011-Present). His current research interests include discovering the mechanisms (with a focus on mitochondrial impairment and oxidative stress) involved in human diseases and the development of safe and clinically-applicable therapeutic options against these complications.
