Barry P Rosen, PhD

Distinguished Professor, Department of Cellular Biology and Pharmacology
AHC2 673A

Barry P. Rosen joined the FIU College of Medicine from Wayne State University School of Medicine, where he is Distinguished Professor of Biochemistry and Molecular Biology and Chair of the Department. Dr. Rosen received his B.S. from Trinity College, Hartford, CT and his M.S. and Ph.D. from the University of Connecticut.

After an NIH postdoctoral fellow at Cornell University, he joined the faculty at the University of Maryland School of Medicine, where he rose to Professor.

In 1987 he took the Chair at Wayne State, and under his stewardship the Department of Biochemistry and Molecular Biology took the lead in structural biology at Wayne State University.

Professor Rosen is an internationally recognized expert in the field of heavy metal transport and detoxification, specializing in the molecular mechanisms of arsenic detoxification. He has published more than 300 papers, reviews and books and is the holder of two grants from the National Institute of Health. He is recipient of numerous awards, including Basil O'Connor Award from the March of Dimes, Maryland Distinguished Young Scientist Award, Josiah Macy, Jr. Faculty Scholar Award, Gershenson Distinguished Faculty Fellow Award (WSU), Outstanding Graduate Mentor Award (WSU), Lawrence Weiner Award (WSU).

He has been on many national and international panels at NIH, NSF, and American Heart Association, and on multiple editorial boards. Dr. Rosen was recently selected to be a Distinguished University Professor, the highest honor awarded to a Wayne State University faculty member. He was President of the Wayne State University Academy of Scholars and President of the American Association of Medical and Graduate Departments of Biochemistry until his move to FIU.

Research Interests:
Pathways of arsenic uptake and detoxification (NIH Grant R37 GM55425)
The overall goal of research in the Rosen laboratory is a detailed molecular analysis of the arsenic transporters and modifying enzymes.Arsenic, a Group 1 human carcinogen, ranks first on the EPA's Superfund list. Arsenic enters the human body from both geological and anthropogenic sources. Because of the ubiquity of arsenic in the environment, every organism has developed transport systems for the efflux and detoxification of arsenic. Chronic exposure to arsenic has been linked to cardiovascular and peripheral vascular diseases, neurological disorders, diabetes and various cancers. Arsenic-containing drugs are used as chemotherapeutic agents for the treatment of leukemia and parasitic diseases. An understanding of both arsenic chemistry and the molecular details of arsenic transport systems is essential for alleviating the problems of arsenic toxicity, as well as for the rational design of drugs to treat drug-resistant microbes and cancer cells.
