Tomás R. Guilarte, PhD, is a leading scientist, educator, and academic leader. His research focuses on mechanism-based neurotoxicology and neuroscience using behavioral, cellular, and molecular approaches, ranging from studies using primary culture of neural cells to the application of brain imaging technologies. Dr. Guilarte's laboratory has been one of the pioneers in the application of molecular imaging techniques in neurotoxicology to understand the detrimental effects of environmental toxins on the central nervous system. Dr. Guilarte is internationally recognized for elucidating the central nervous system effects produced by exposure to low levels of lead during development and the development of therapeutic strategies for reversing the detrimental effects of lead on the brain. Another major focus of Dr. Guilarte's research is to both assess the effects of environmental chemicals on the central nervous system and assess the onset and progression of neurodegenerative diseases, using a biomarker protein called translocator protein 18 kDa. Dr. Guilarte serves in key editorial positions and plays an active role in several scientific organizations. He has served as president of the Neurotoxicology Specialty Section of the Society of Toxicology and has been a member of numerous NIH study sections and review panels. Dr. Guilarte also has a strong track record of mentoring and training pre-doctoral students and post-doctoral fellows, many of whom have won numerous awards in national and international student competitions.
