Dr. Sapkota is the Director of CONSERVE: A Center of Excellence at the Nexus of Sustainable Water Reuse, Food & Health, a multi-institution Center funded by the U.S. Department of Agriculture, National Institute of Food and Agriculture (2016-2021). She is also the Principal Investigator of UMD Global STEWARDS (STEM Training at the Nexus of Energy, Water Reuse and Food Systems), a National Research Traineeship (NRT) program funded by the National Science Foundation (2018-2023).
The mission of CONSERVE is to facilitate the adoption of transformative on‐farm water treatment solutions that enable the safe use of nontraditional irrigation water (e.g. reclaimed water, return flows) on food crops. The overarching goal of the UMD Global STEWARDS NSF NRT is for graduate trainees to become adept at working and communicating across food-energy-water (FEW) disciplines, enabling transformative discoveries that can only be realized through transdisciplinary approaches and systems-based thinking.
Dr. Sapkota received a PhD in Environmental Health Sciences from the Johns Hopkins Bloomberg School of Public Health and an MPH in Environmental Health Sciences from the Yale School of Public Health. After completing her doctorate, she engaged in post-doctoral fellowships at the Johns Hopkins Bloomberg School of Public Health and the Environmental Microbial Genomics Group at Ecole Centrale de Lyon in Lyon, France.
She is the recipient of the 2012 Eric Mood New Professional Award from the Yale School of Public Health that recognizes the career of a Yale alumnus/a who demonstrates outstanding leadership potential and creativity in the practice of public health. Dr. Sapkota is also the recipient of the 2015 Jerry P. Wrenn Outstanding Service Award, the 2018 Research and Development Award and the 2019 Leda Amick Wilson Mentoring Award from the University of Maryland School of Public Health. In 2017, she represented the Core Fulbright U.S. Scholar Program and the United States as a Fulbright Senior Researcher in Chitwan, Nepal.
Dr. Sapkota's research interests lie in the areas of environmental microbiology, environmental microbial genomics, exposure assessment and environmental epidemiology, and she has published over 70 journal articles in these areas. Her research group evaluates the complex relationships between environmental microbial exposures and human infectious diseases, with a special focus on assessing the public health impacts associated with water reuse. Much of her group's work seeks to 1) characterize the microbiome of recycled water sources and 2) understand how direct and indirect exposures to these sources can impact the human microbiome and infectious disease risk.
Dr. Sapkota is seeking talented undergraduates, graduate students and post-docs to join her group. In particular, her lab will have openings for Master's and Doctoral students entering in the 2021-2022 academic year. She currently serves as a mentor to students in the following programs: MPH, MS and PhD in Environmental Health Sciences.
