Biography

Justin Remais is an engineer and environmental health scientist whose research focuses on transmission control of infectious diseases in changing environments. He studies how urbanization, migration, and climate variability affect the spread of pathogens and the risks of diseases they cause. Remais’s group develops models that integrate epidemiology, environmental science, and social data to forecast disease risks and assess public health interventions. His work advances the understanding of sanitation, water, and climate systems that shape future global health for decades to come. Remais's group has shown that famine induces long-term intergenerational effects on infectious disease transmission, led an international research effort to estimate the burden of water, sanitation, and hygiene-attributable infectious diseases in China in the context of climate change, and published seminal work in the Lancet on the health consequences—both adverse and beneficial—of rapid urbanization in China, interacting with population aging and sociodemographic trends. Appointed to the Berkeley faculty in 2016, Remais is the Chair of Environmental Health Sciences at UC Berkeley’s School of Public Health, where he teaches and mentors students in environmental and epidemiological modeling, risk analysis, and global health policy.
