Environmental and Occupational Health

Every community deserves safe air, water, soil, and food, just as every worker deserves a safe and healthy workplace. ERG’s health scientists, occupational safety and health professionals, and industrial hygienists have dedicated their careers to protecting and improving the health and well-being of our workers, vulnerable communities, and the population at large. ERG has helped government agencies to better understand how environmental and occupational exposures to chemical, physical, biological, and radiological hazards can affect people’s safety and health. Whether it be identifying the occupational hazards at laboratories, evaluating the impacts of contaminated drinking water on residents near hazardous waste sites, or educating workers on how to improve their physical well-being, our multidisciplinary team applies sound scientific principles and uses both established and innovative approaches to help solve problems. From in-depth research and data compilation to scientific assessment and policy and regulatory analyses, ERG’s safety and health support services promote sound risk management decisions and prevention strategies.

Kathleen Brady

Behavior change requires much more than the perfect slogan. I like to figure out what motivates people to move and keeps them awake at night, then create messages and materials that inspire them to improve their safety, health, or the environment. That said, a little alliteration or a catchy rhyme never hurts!

Jeff Cantin

When I tell people I’ve worked at the same company for almost three decades, they are often astonished: Who would want to do the same thing for so long? What they don’t realize is that it’s never the same. I consider myself fortunate that, throughout my career at ERG, the work I do has always been interesting, challenging, and changing with the times.

Naida Gavrelis

I am passionate about doing all we can to protect people’s health and well-being and the environment in which we live. I have devoted my career to addressing health risks encountered in our communities and workplaces. I strive to solve problems using common sense and sound science.

Chris Lamie

My work is all about continual improvement. Whether it’s tackling emerging challenges in our environment, setting and working toward incremental sustainability goals, or designing information products that reach new audiences in innovative ways, I enjoy opportunities to raise awareness, raise the discourse, and help our clients improve human well-being and the health of our planet.

Arlene Levin

I was thrilled when I started working for ERG and found that I could apply my passion for environmental and occupational health by working for government agencies that promote and protect the health of individuals, workers, and the environment. This nexus has allowed me to pursue incredibly interesting work across myriad health-related topics and to help my clients plan, develop, and implement successful programs and initiatives.

Whitney Long

I'm a ‘black sheep,’ a scientist in a family full of artists. That creative background gives me a different perspective on the kinds of technical problems that don't have ready solutions available. At ERG, I'm free to let my creative side help my technical side find solutions to our clients' large, complex problems.

Kevin Sikora

We’ve come a long way from the days of mad hatter disease and painting radium watch dials but, with workplace fatalities in the United States hovering just above 4,500 per year since 2009, we still have work to do. I’m proud to be part of that work at ERG. I’m pretty sure that number won’t reach zero in my lifetime, but I know that helping our clients develop better regulations and guidance to protect the nation’s workforce gets us one step closer every day.

John Wilhelmi

Clean air, safe workplaces, a stable climate for generations to follow—these are just some of the ideals that motivate my daily work. I strive to bring the best available science to our nation’s current and emerging environmental health and occupational safety issues. Solutions are important to me. Whether proposing air pollution controls to reduce community air toxics exposures or identifying engineering controls to address occupational hazards, I seek common sense and actionable solutions that benefit the health and safety of our population and workforce.
