What must be done to reduce the harmful health effects of major storms and make our communities ready for the short- and long-term impacts of severe weather events?

Picture a coal power plant: a building with tall smoke stacks with big plumes of gasses coming out of them. By now, we know that those gasses aren’t great for our health or the environment. But how bad are they? That’s where Professor Cory Zigler comes in.

What is the cost of homelessness in Rhode Island? Do we measure it in dollars, hours, square footage? Or is it measured by sleepless nights, persistent coughs, uncertain futures? The reasons Rhode Islanders remain unhoused are varied, but the results are the same: marginalization and the fight to keep a stable footing.

Inside your refrigerator and pantry, plastic is everywhere. There’s plastic wrap, storage bags and bins, clamshell takeout containers, beverage bottles, and condiment tubs, of course. Plastics (synthetic polymers) are also a component of the multi-layer material that make up chip bags and encase granola bars. Tin, steel, and aluminum cans, like the type that might hold beans or a soda, are lined with plastic. Even many paper products, such as paper cups and frozen food trays, are coated in–you guessed it–plastic.

Dean Jha addressed the School of Public Health at this annual fall event, showcasing the school’s impact by sharing the stage with members of the school’s community, including student, staff and faculty speakers.

Most of us know that lead exposure is bad for our health. To protect us, especially children, the US hasn’t allowed lead in gasoline, house paint, children’s toys, dishware or jewelry for decades. But there are a few places where lead has stuck around. Today we’re taking a look at one of the least well known, and most stubborn sources of lead exposure in the US - guns and ammunition. 

Massachusetts and Connecticut are now the first states to ban the use of PFAS, or “forever chemicals,” in protective gear worn by firefighters.

A team led by Professor Erica Walker has received federal funding to conduct the first air-quality and community noise assessment of Mississippi communities impacted by the production of wood pellets.

Brown researchers compared assisted living residents in Florida who evacuated during Hurricane Irma to those who sheltered in place in order to determine the health risks inherent in long-term care disaster planning and response.

Brown researchers examined hundreds of thousands of veterans’ health records to determine if exposure to burn pits on military bases correlates with elevated risk for respiratory and cardiac health conditions.

American life expectancy started dropping even before the pandemic. It’s a critical barometer of our nation’s health and a sign that all is not well in the U.S.

Despite being on the front lines of the climate crisis, the health care sector is also one of the greatest contributors to greenhouse gas emissions. A new study from Brown researchers looks at these decarbonizing efforts across the globe.

MPH student Rosemelly Jimenez Medal's father has worked as a short-haul trucker for over 25 years, and she noticed that he was struggling to hear conversations at dinner. So Jimenez Medal teamed up with her father and noise researcher Erica Walker, RGSS Assistant Professor of Epidemiology at Brown University, to conduct hearing screenings on short-term truckers in California.

Here are some of the noisiest parts of Providence, based on 5,000 noise complaints called to police.

Noise pollution is a physical and mental stressor with real health impacts, Professor Erica Walker tells NPR. "It's going to the emergency room for a panic attack, it's 'I can't sleep,' 'I can't hear my children.' It's all of those things," she says.

Professor of epidemiology Erica Walker weighed in for this comprehensive article for the New York Times.
