Gary L. Johanning

Program Director, Viral Oncology and Immunology

Gary Johanning, Ph.D., focuses on cancer prevention and therapy by targeting viruses that play critical roles in tumor development. Johanning’s laboratory was one of the first to show that the vitamin folic acid promotes DNA methylation by providing methyl group substrates.

He was also involved in early studies showing the beneficial effects of micronutrients in preventing human papillomavirus (HPV) infection, and that micronutrients slow the development of resistance to chemotherapy. His recent research interests have focused on endogenous retroviruses and their involvement in the development and progression of cancer and other diseases.

Before joining SRI Biosciences, Johanning was an associate professor of nutrition sciences at the University of Alabama at Birmingham, and an associate professor of comparative medicine at M.D. Anderson Cancer Center in Houston.

Johanning has been a principal investigator on several grants funded by the National Institutes of Health and several foundations. He has authored or co-authored more than 60 publications, reviewed manuscripts for more than 25 journals, and is on the editorial board of five journals.

Johanning obtained his Ph.D. in biochemistry from the University of Missouri-Columbia. He then completed postdoctoral fellowships in nutritional biochemistry, both at Missouri and at Case-Western Reserve University in Cleveland. He has mentored several M.S. and Ph.D. students.
