A Single Mission: Protecting People and Places—Introducing Environmental Medicine and Public Health Sciences

Wednesday, May 27, 2026

University of Rochester Medicine has announced the formation of the Department of Environmental Medicine and Public Health Sciences, which unites biomedical toxicology and population-level environmental and public health expertise to accelerate discoveries into policy, clinical practice, and community action.

The new department, officially approved by the University of Rochester Board of Trustees in February 2026, will be led by B. Paige Lawrence, PhD, current chair of Environmental Medicine. Ann Dozier, PhD, chair of the Department of Public Health Sciences, recently retired from URochester Medicine.

“The new Department of Environmental Medicine and Public Health Sciences brings together decades of scientific discovery and community-centered public-health practice,” said David Linehan, MD, CEO of the University of Rochester Medical Center and Dean of the School of Medicine and Dentistry. “By linking molecular and toxicological insight with population science and policy, we can move faster from discovery to action—reducing exposures, improving health equity, and shaping policies that protect people and improve health.”

“We are merging because today’s public-health challenges require both deep mechanistic science and rigorous population approaches,” said Lawrence. “Bringing together environmental toxicology, epidemiology, health-services research, and policy work will create faster pathways from laboratory discovery to population interventions, health-system change, and policy implementation—while expanding interdisciplinary training for students at every level.”

Study Examines How Pregnancy May Help the Body Eliminate Mercury from Fish

Monday, March 16, 2026

Researchers at the University of Rochester are investigating whether natural biological changes during pregnancy help reduce a fetus’s exposure to mercury. The project will examine how the maternal gut microbiome and pregnancy-related physiological changes may increase the body’s ability to eliminate methylmercury, the toxic form of mercury commonly found in fish, before it reaches the developing fetus.

“Much of environmental health research focuses on identifying risks,” said Matt Rand, PhD, associate professor of Environmental Medicine and the study’s principal investigator. “What excites us about this project is the opportunity to understand the body’s natural defenses. Namely, how pregnancy itself may help protect the fetus from environmental exposures like mercury.”

Building on decades of mercury research

Concern about prenatal mercury exposure has driven decades of research into how fish consumption affects fetal brain development. One of the most consequential efforts is the Seychelles Child Development Study, a landmark international research program that has followed families in the Seychelles for decades.

That work, led by scientists at the University of Rochester, has found no measurable harm to children’s neurodevelopment in a population that consumes roughly ten times more fish than in the United States. These and other findings have helped shift public-health guidance toward encouraging pregnant people to eat fish to obtain key nutrients important for fetal brain development.

Still, questions remain about how the body manages mercury exposure during pregnancy.

Team Science Showcase: The People and Partnerships Moving Microplastics Research Forward

How a small project between a university lab and a city water system grew into a national model

Public concern about microplastics and health has grown sharply over the past several years. Questions like “Are plastic cutting boards safe?” and “Should I drink out of plastic water bottles?” are prevalent, but straightforward answers to these seemingly simple queries are not.

While new research on levels of microplastics found in the human body has recently raised flags for many, scientists at the University of Rochester have been asking questions, building teams, and uncovering how environmental exposures impact human health for decades. With the knowledge, partnerships, and systems they’ve put in place through the University’s Environmental Health Sciences Center (EHSC), now celebrating its 50th year of funding from the National Institutes of Health, they’re poised to provide answers.

“The EHSC was built on the idea that the biggest environmental health challenges require teams that cross disciplines, institutions, and communities,” said Paige Lawrence, PhD, chair of the department of Environmental Medicine at the University of Rochester School of Medicine & Dentistry. “Our microplastics work is a perfect example of how that model accelerates discovery. By bringing engineers, toxicologists, ecologists, and local partners together, we’re able to ask deeper questions and develop solutions that matter for people’s daily lives.”

The long-standing collaborative culture fostered by the EHSC led to the launch of the Lake Ontario MicroPlastics Center (LOMP) in April 2024. One of six federally funded Centers for Oceans and Human Health in the nation, LOMP marked the culmination of a decade of collaborative work among University of Rochester and Rochester Institute of Technology (RIT) researchers, community organizations, and local and state government to understand and reduce microplastic pollution in local waterways.

“Microplastics research in Rochester didn’t start with a single project—it started with relationships,” said Katrina Korfmacher, PhD, professor of Environmental Medicine at the University of Rochester School of Medicine & Dentistry. “For years, our faculty have worked alongside community and government partners who are deeply invested in water quality. LOMP is an extension of the EHSC’s long-standing commitment to doing science in partnership with communities.”

Korfmacher co-directs LOMP with Christy Tyler, PhD, professor in the Thomas H. Gosnell School of Life Sciences at the Rochester Institute of Technology. Today, their teams are working to understand how microplastics move through the Lake Ontario ecosystem and how they may affect human health under varied environmental conditions—research made possible by a discovery that connects back to the EHSC.

The Society of Toxicology Recognizes Professors with Awards

Thursday, February 5, 2026

Paige Lawrence, the Wright Family Research Professor and the director of the Institute for Human Health and the Environment, received the Society of Toxicology Education Award. 

Alison Elder, an associate professor of environmental medicine, received the society’s Translational Impact Award.

Congratulations to both.

Researchers raise concerns about faster aging, possible early-onset dementia, for children and young adult cancer survivors

Wednesday, January 7, 2026

Adolescent and young adult cancer survivors age faster than their peers who did not have cancer, according to a new study led by AnnaLynn Williams, an assistant professor of surgery, of public health sciences, and at the Wilmot Cancer Institute. The study also describes how accelerated aging occurs both at the cellular level and in brain function, such as memory, attention, and the ability to process information.
