Dharni Vasudevan
Vasudevan’s research concerns the environmental fate of chemicals, such as pharmaceuticals and pesticides, and her work focuses on the mechanisms by which these compounds and related model substructures interact with surfaces in soil and aquatic environments. A professor at Bowdoin since 2004, Vasudevan was the chair of the Department of Chemistry from 2014–2018, and she currently serves as associate dean for faculty development and inclusion. In 2013–2014, she was a visiting scientist in the Exposure, Epidemiology, and Risk Program at the Harvard School of Public Health. Widely published (with Bowdoin student coauthors) in peer-reviewed publications and a frequent speaker at conferences and colleges and universities, Vasudevan has been awarded research grants from the National Science Foundation, the Merck/AAAS Undergraduate Science Program, the US Department of Agriculture, and many others. As an undergraduate student she really got hooked on environmental chemistry when I discovered that chemical structure dictates chemical properties and their ‘personalities,’ which in turn determines how they behave in the natural environment, which in turn impacts human and wildlife exposure to them. Vasudevan, who is jointly appointed to chemistry and environmental studies, routinely team-teaches with other Bowdoin professors, and leads students in her research lab, a group those students fondly refer to as “Team Dirt.” Her research work focuses on the mechanisms by which organic and inorganic compounds interact with mineral surfaces in soil and aquatic environments.
