Barry P. Rosen joined the newly founded Herbert Wertheim College of Medicine in 2009 as associate dean for basic science research. He retired as a distinguished university professor in 2025 after five decades studying heavy metal transport and detoxification.
Rosen is an international expert on arsenic whose research was continuously funded by the National Institutes of Health and the National Science Foundation for over 50 years, ranking among the top 100 longest continuously funded NIH projects.
Over his career, Rosen produced nearly 400 research publications with over 34,000 citations, earning him recognition as a Highly Ranked Scholar by Scholars GPS, placing him among the 0.05% of all scholars globally. His research was featured on the covers of five scientific journals.
Rosen is a Senior Member of the National Academy of Inventors with six patents to his name. He was elected President of the Association of Medical and Graduate Departments of Biochemistry and Fellow of the American Academy for Microbiology and the American Association for the Advancement of Science. Among his many accomplishments, Rosen notes that he trained 22 doctoral students, 55 postdoctoral associates and multiple visiting scholars.
Before joining FIU, he served as a distinguished university professor and chair of the Department of Biochemistry and Molecular Biology at Wayne State University School of Medicine, and as a professor in the Department of Biological Chemistry at the University of Maryland.
Rosen received his BS in biology from Trinity College in 1965 and Ph.D. in biochemistry from the University of Connecticut in 1969, followed by an NIH Postdoctoral Fellowship at Cornell University.
