I’m an environmental public health scientist
with a broad background in
epidemiology, toxicology, and research translation. I have
a passion for teaching
and for communicating science. I’m especially interested in how we can use
scientific information to create
effective chemicals policy that protects
the environment and public health.
In 2019, I am based in Dhaka, Bangladesh, where I am collaborating with
the Environment and Social Development Organization
on local pollution issues, with special emphasis on lead, mercury, plastics, and PFAS.
My work focuses on the use of scientific data in forming effective
I have extensive experience with chemicals regulation in
the United States, including a year as an
AAAS Science & Technology Policy Fellow
hosted within EPA’s Design for the
I have a special interest in the effectiveness of the restriction and authorisation processes
under the European Union’s REACH chemicals policy,
through ongoing collaborations with the
European Environmental Bureau,
the Health and Environment Alliance,
and other EU- and US-based organizations.
I teach regularly in the Providence and Boston areas.
I teach regularly at at
Boston University’s Sargent
College; in the last two years I have also taught at the Brown University School of Public Health
and the Environmental Studies Program at Boston College.
I am affiliated with Brown University’s Center for Environmental Health and Technology.
Previously, I’ve taught extensively at
as well as at the
Boston University School of Public Health.
I am also available for writing and
editing on environmental health, especially including chemicals and other toxicants,
as well as environmental health policy.

Courses I’ve taught
- Environmental Health and Policy, a
“fundamentals” course on environmental public health, covering the basic
scientific approaches (toxicology, epidemiology, risk assessment), the policy and
regulatory context, and emerging problems in environmental health.
- Foundations of Environmental Science
and Introduction to
These introductory courses, targeted at Environmental Studies majors and non-majors respectively, emphasize the
human-environment connection, including energy and climate, agriculture,
waste, and toxics.
- Environmental Ethics and the End of the World, a
seminar on environmental apocalypse and environmental ethics through the lens of literature.
- Cities, Environment, and Health, an overview of the
imapacts of urban design on health and the environment. This class covers the basic
history and theory of urban planning and design, examines the impacts of
different design approaches, and considers the prospects for the future.
Spoiler alert: While cities have their challenges, they can be very, very good
for both health and environment.
- Methods in Environmental Health Sciences, a
laboratory-based introduction to research methods in the field, including
toxicology, epidemiology, exposure assessment, and risk assessment.
- Environmental Policy, an overview of environmental law,
policy, and regulation. This course emphasizes US governmental structures and
the resulting regulations; because of my particular experience and interests, the regulation
of chemicals is highlighted.
- The Global Supply Chain, a senior seminar focusing on
global health and environmental impacts of manufacturing, trade, and
In ongoing development: The Health
Studies Guide is a resource for communities affected by or concerned about
Scammell and I developed the Guide with help from a number of other collaborators.
