I am an interdisciplinary scientist working at the intersection of functional microbiology and atmospheric chemistry.I have been an Assistant Professor in the School of Natural Resources and the Environment (SNRE) since January 2017. I currently have faculty affiliations with the BIO5 Institute, the department of Hydrology and Atmospheric Sciences, the Genetics Graduate Interdisciplinary Program (GIDP), and the Global Change GIDP. I was the Director of the Biosphere 2 Tropical Rain Forest from 2018-2021.Show Less
