About us

We study air pollution exchange across the building envelope. We spend the majority of our lives indoors, so understanding the composition and chemical transformations of the air we breathe indoors is critical for understanding and ultimately mitigating our indoor chemical exposures. We are interested in how outdoor-derived pollution from varied sources enters an indoor space and chemically transforms, as well as how indoor-derived pollution impacts the surrounding outdoor environment. Learn more about the Ditto group’s research.

If you are a prospective undergraduate: please reach out to learn more about independent study opportunities.

If you are a prospective graduate student: please reach out and describe your background, future research interests, and connections to our group. Note that our Ph.D. application usually becomes available in September and the deadline is in December of any given year.

Schematic showing our research areas of interest: chemical composition of what enters homes, indoor chemical/physical processes, indoor exposures, and impacts on outdoor air.
