Tomas R. Guilarte, Ph.D.


Dr. Tomas R. Guilarte, a professor with Johns Hopkins Bloomberg School of Public Health, researches the effects of lead on brain functioning in experimental animals.  Under his direction, his lab has explored the effects of lead on learning. Among interesting research results to emerge from his lab is the possibility that a mentally stimulating environment can reverse cognitive deficits caused by lead exposure. His research was conducted on rats, but if the results prove to transfer to children, many families stand to benefit.


Dr. Tomas R. Guilarte is a professor at the Johns Hopkins Bloomberg School of Public Health in the department of Environmental Health Sciences.  He is also director of an emerging Program in Molecular Imaging. His current area of study is the molecular and behavioral effects of lead and manganese exposure. His laboratory is also developing an early biomarker of Parkinson's disease using non-invasive brain imaging techniques. Dr. Guilarte has a bachelor’s degree in Zoology and a master’s degree in Medical Physics,  both from the University of Florida in Gainsville. He earned his Ph.D. at Johns Hopkins in Environmental Health and was given a faculty appointment immediately after his Ph.D. In 1990, he was given a joint appointment in the Division of Human Nutrition in the Department of International Health.  Dr. Guilarte has served in several national and international scientific organizations and, in 1999, he was elected President of the Neurotoxicology Specialty Section of the Society of Toxicology.
