Much of her research has specifically focused on “[characterizing] exposure to a wide range of environmental hazards in the general population with a real emphasis on identifying vulnerable populations or highly exposed populations,” Dr. Zota says.  . . .

Meet our 20 Pioneers under 40 in Environmental Public Health: Megan Latshaw, PhD

Jan 18, 2018— Megan Latshaw, PhD, is all about making public health work for the people. Throughout her career, she has realized public health has the potential to affect communities.

“If you think about what it is that is killing people all around the globe, it is chronic diseases and, as we know, most chronic diseases are not infectious. The Human Genome Project has not provided the key to unlocking chronic disease; I think environmental health and epigenetics is the next frontier in figuring out how we can make the world a healthier place,” Dr. Latshaw shares.  . . .

Meet our 20 Pioneers under 40 in Environmental Public Health: Sara Wylie, PhD

Jan 11, 2018— Sara Wylie, PhD developed an interest in science from a young age, having grown up with two developmental biologists as parents. As she got older and started asking her own questions, her focus turned to how chemicals, especially those that look like hormones to the body, can shape the life course. As she went through school and studied to be an anthropologist of science, these interests grew even more complex.  . . .

CHE's Next Big Project

Dec 19, 2017— Hello CHE Friend,

My name is Emma, and I am CHE’s new Program Associate. I started with CHE in September and have learned so much in these three short months. I studied environmental health a bit during my MPH program at Columbia University Mailman School of Public Health, but my main focus was on health promotion and communications. Since starting at CHE, I have being learning all about environmental health science and listening to scientists share their work. And, I have been telling anyone and everyone I know about what I am learning because I believe this is stuff everyone should know. This is why I am so excited about starting Because Health.  . . .

Meet our 20 Pioneers under 40 in Environmental Public Health: Joan Casey, PhD

Dec 14, 2017— Like many who find themselves in environmental health, Joan Casey’s interest in studying the impacts of industrial agricultural came when she heard a startling fact.
