Research Description

 Justin Remais is Professor of Environmental Health Sciences in the School of Public Health, where he has served as the Chair of the Division of Environmental Health Sciences since 2017. An engineer by training, his research uses statistical, mathematical, and computational approaches to study the impact of environmental change on the dynamics of infectious disease transmission. He leads a cluster of studies examining the spread of West Nile virus, TB, leptospirosis, schistosomiasis, coccidioidomycosis, and enteric infections as they respond to rapid urbanization, industrialization, migration, changes in water resources, and a changing and more variable climate, among other factors. His research group has been continuously funded by NIH/NSF since 2006 to undertake collaborative research with partners in California, China, Ecuador, Senegal and elsewhere that address fundamental questions regarding how infectious diseases spread, and what can be done to interrupt their transmission. He has led (as PI or co-PI) >$17 million in extramural research projects since being appointed to the Berkeley faculty. He has served on the editorial board of PLoS Neglected Tropical Diseases since 2008 (where he is now Deputy Editor), and Academic Editor of PLoS Global Public Health since the journal's launch in 2021.

Prof. Remais' group was the first to show that famine induces long-term and intergenerational effects on infectious disease transmission (PNAS), and he led the first international research effort to estimate the burden of water, sanitation and hygiene-attributable infectious diseases across China in the presence of a changing climate (Nature Climate Change). He also led an international team that published seminal work in The Lancet on the health consequences—both adverse and beneficial—of rapid urbanization in China, and its interaction with population aging and other demographic trends. He has led research investigating the effects of climate change on pathogenic fungi; COVID-19 transmission dynamics within school settings; Valley fever epidemiology in a changing California; and the influence of environmental and social dynamics on the transmission of environmental pathogens. His group's  major NIH-funded research has developed new approaches for simulating and optimizing surveillance networks to detect existing and emerging infectious diseases under changing epidemiological and environmental conditions, with a focus on diarrheal diseases, malaria, dengue, leptospirosis, TB, Japanese encephalitis, schistosomiasis and HFMD. His research projects in California include an investigation of the changing epidemiology of West Nile virus in the state, and research on the spread of coccidioidomycosis through drought and heavy rainfall cycles. Prof. Remais received his MS in Civil and Environmental Engineering and PhD in Environmental Health Sciences from the University of California, Berkeley.

Safe Bay Area school reopenings may be possible with stringent social-distancing measures and reductions in community transmission

As the fall school semester is nearly underway, discussions are intensifying on whether, and how, to reopen schools amid the ongoing COVID-19 pandemic. A new study, led by researchers at UC Berkeley, finds that in-person classes in the Bay Area may be possible for elementary schools, but only if schools can successfully limit contact between students from different classes. In contrast, remote learning may be the only safe option for middle and high schools until community transmission is dramatically lowered.

Pesticides speed the spread of deadly waterborne pathogens

Widespread use of pesticides and other agrochemicals can speed the transmission of the debilitating disease schistosomiasis, while also upsetting the ecological balances in aquatic environments that prevent infections, finds a new study led by researchers at the University of California, Berkeley.

How fat prawns can save lives

Before bite-sized crustaceans like crayfish, shrimp and prawns land on our dinner plates, they first have to get fat themselves — and it turns out they relish the freshwater snails that transmit the parasite that causes schistosomiasis, the second most devastating parasitic disease worldwide, after malaria.

When it comes to climate change, don’t forget the microbes

Scientists are rightly focused on anticipating and preventing the major impacts that climate change will have on humans, plants and animals. But they shouldn’t forget the effect on Earth’s microbes, on which everything else depends, warns a group of 33 biologists from around the globe.
