She is an environmental epidemiologist who works with a multi-disciplinary and multi-national team of scientists to understand the ways in which social and environmental processes impact waterborne diseases. Over the past decade, she has documented the reemergence and persistence of schistosomiasis in southwest China, including the patterns of reinfection and the potential role of agricultural practices in sustained transmission. Her recent work includes the application of next generation genomics to understand barriers to disease elimination in residual transmission hotspots. Her current research also includes work to estimate the potential impacts of climate change on respiratory health and diarrheal diseases. She has on-going research studies in the Colorado Front Range, Sichuan, China, and northeast Thailand.
