Complete list of biomedical publications:

Dr. Brad R. Weiner has been an active researcher in the Chemistry Department at the University of Puerto Rico – Río Piedras for over thirty years.  Dr. Weiner is the author and/or co-author of over 150 peer-reviewed publications and 8 patents in the areas of molecular reaction dynamics, materials science and nanotechnology.  His research group is now actively involved in biomedical applications of carbon and carbon-metal hybrid nanoscale materials. These applications include using the nanoparticles as anti-bacterial agents[1], anti-cancer treatments[2],[3],[4], active biosensors and MRI contrast agents[5],[6]. Dr. Weiner is currently serving as the Contact Principal Investigator for the “University of Puerto Rico / M.D. Anderson Cancer Center – Partnership for Excellence in Cancer Research”, which is funded by the National Cancer Institute (NCI) of the National Institutes of Health.  This partnership, now in its 20th year, is dedicated to expanding the cancer research enterprise with special emphasis on infection-driven malignancies, and reaching NCI-designation for the UPRCCC. Dr. Weiner has dedicated more than 25 years as a research administrator to the development of Science and Technology in Puerto Rico.  He has led islandwide efforts funded by the National Science Foundation (NSF) U.S. Department of Energy, National Aeronautics and Space Administration (NASA), U.S. Department of Education, and the National Institutes of Health.  Dr. Weiner served as the Dean of the College of Natural Sciences at the University of Puerto Rico-Río Piedras from 1999-2013.  Dr. Weiner spent a sabbatical year away from academia in 2004, serving as the Director of the Division of Higher Education for NASA, based at Headquarters in Washington, D.C.  Dr. Weiner received a Bachelor of Arts degree in Chemistry from Grinnell College in 1981, a Ph.D. in Chemistry from the University of California – Davis in 1986, and served as a National Research Council Postdoctoral Fellow at the Naval Research Laboratory prior to joining the faculty at the University of Puerto Rico in 1988.
