Overview
Dr. Gurumurthy “Ram” Ramachandran joined as Professor in the Department of Environmental Health and Engineering in the Bloomberg School of Public Health at Johns Hopkins University in 2016. He is the Director of the Johns Hopkins Education and Research Center for Occupational Safety and Health funded by the National Institute for Occupational Safety and Health (NIOSH). Starting in July 2019, he has also been appointed as Deputy Chair for the Department of Environmental Health and Engineering.
He has conducted research in various areas relating to human exposure assessment in occupational, residential, and outdoor settings. His research has included the development of occupational exposure assessment strategies for airborne contaminants. He has conducted pioneering studies in occupational hygiene decision-making that synthesizes mathematical exposure models, monitoring data, and probabilistic expert judgment within a Bayesian framework. He has led or participated in multi-disciplinary teams engaged in numerous community and occupational exposure assessment and epidemiological studies in the US, India, and Canada, and Bangladesh. He collaborates with colleagues in International Health on epidemiological studies in Bangladesh relating to cookstove emissions, with toxicology colleagues on designing exposure chambers for animal studies, and colleagues in the SOM on lung dosimetry modeling. He is co-leading the Exposome Collaborative of the Johns Hopkins University.
He has served as a member of the Board of Scientific Counselors to the National Institute of Occupational Safety and Health (NIOSH) and advisory committees for the National Academy of Sciences (NAS) and the US Environmental Protection Agency (USEPA). He is also serving on the editorial boards of the Annals of Work Exposures and Health, and the Journal of Occupational and Environmental Hygiene. He has a Bachelor's degree in Electrical Engineering from the Indian Institute of Technology, Bombay, a Master's degree in Environmental Engineering, and a Ph. D. in Environmental Sciences and Engineering from the University of North Carolina.
