My research interests have included source and drinking water microbiology, microbial cycling and transformation of pollutants, global environmental health, epidemiology of waterborne diseases, and community based participatory research methods for community engagement. I have both directed and participated in water quality related projects in the US, Canada, the UK, Honduras, Mexico, India, Russia, the Philippines and China. I served as the PI of the NIH-funded Montana IDeA Networks for Biomedical Research Excellence (INBRE), a statewide program designed to build research and training in infectious disease and environmental health. At UMass Amherst, I intend to renew the relationships built through the INBRE program and work towards a consortium for environmental health equity. I am also in the process of expanding my research interests to include health inequities in Latin American and the Caribbean, through my role as co-chair of the PAHO Foundation technical advisory group.
