Ravi Sahu

Assistant Professor

biography

Dr. Ravi Sahu obtained his B.Sc in biology, Physics and chemistry from Allahabad University and M.Sc in biochemistry from Dr. R.M.L. Avadh University in India. He completed Ph.D from Sanjay Gandhi Postgraduate Institute of Medical Sciences at Lucknow, India. He then began his postdoctoral career determining the role of natural compounds in cancer chemoprevention at University of Pittsburgh at Pittsburgh, PA and Texas Tech University Health Sciences Center at Amarillo, TX. His second postdoctoral work at Indiana University was focused on investigating the impact of various pro-oxidative stressors in the pathogenesis of cutaneous immunity and non-melanoma skin cancer. Currently he is an Assistant Professor in the Department of Pharmacology and Toxicology, Boonshoft School of Medicine at Wright State University, Ohio, United States.

 

Area of Interest
