Melinda A Beck

Melinda Annetta Beck is an American nutritionist and professor at the Gillings School of Global Public Health at the University of North Carolina at Chapel Hill where she also serves as interim department chair. Her research investigates the relationship between nutrition and immune response to infectious disease. She was elected Fellow of the American Association for the Advancement of Science in 2022.

Early life and education Beck studied zoology at the University of California, Berkeley. She moved to the California Polytechnic State University for her master's degree in biological sciences. Her graduate dissertation developed an immunofluorescent test to detect Gardnerella vaginalis. She then moved to Ohio State University, where she studied cell-mediated immunity during re-infection with influenza and received a PhD in medical microbiology and immunology.

Research and career After her PhD, Beck was a postdoctoral researcher at the University of Nebraska Omaha. Beck joined the faculty at the University of North Carolina at Chapel Hill in 1992. She was awarded a Fellowship in the Frank Porter Graham Child Development Center. She was made associate professor in 1998, full professor in 2004 and department chair in 2022. She has shown that following influenza infection, obese mice have a higher mortality rate than their lean counterparts, and that obese individuals do not sustain anti-flu antibodies. She showed that deficiency in antioxidant nutrients can give rise to viral mutations that make viruses pathogenic. 2023 Elected Fellow of the American Association for the Advancement of Science
