We are broadly interested in questions of environmental health. How does the environment experienced by a developing embryo influence health outcomes later in life? Are these interactions adaptive or disruptive? What are the mechanisms? What are the consequences at the individual, population, and ecosystem levels? We are also pursuing projects that examine how environmental quality influences fundamental processes of biological aging. What are the mechanisms by which factors like exposures to contaminants influence aging trajectories? Much of our active research is focused on addressing these questions in environmental models and humans. Check out our website which is updated more frequently.
