Dr. Murray is an Assistant Research Professor in the Maryland Institute for Applied Environmental Health. She is the Program Manager of the UMD Global STEWARDS (STEM Training at the Nexus of Energy, Water Reuse and Food Systems) Program, which is funded by the National Science Foundation (NSF) National Research Traineeship (NRT) grant. The mission of the Global STEWARDS program is to support and prepare graduate students in becoming future leaders focused on innovations at the nexus of food, energy and water (FEW) systems. The program provides opportunities and training for graduate students to become adept at working and communicating across FEW disciplines, enabling transformative discoveries that can only be realized through transdisciplinary approaches and systems-based thinking.

Dr. Murray also works on the CONSERVE Center of Excellence which is led by Dr. Amy Sapkota and supported by a grant from USDA-NIFA. Project CONSERVE investigates transformative on‐farm treatment solutions that enable the safe use of nontraditional irrigation water (such as recycled wastewater) on food crops. 

Dr. Murray’s research interests lie in the fields of environmental health, global health, environmental justice, food safety, and water quality. Her dissertation investigated the influence of private drinking water wells and their proximity to animal agricultural operations on the incidence of foodborne illness in Maryland. She currently teaches the Public Health Science (PHSC) undergraduate course MIEH 331: The Built Environment, Sustainability, and Public Health, and assists the facilitation of the Global STEWARDS graduate courses, MIEH 690, MIEH 691, and MIEH 699. She also recently led a group of Global STEWARDS fellows on a short-term study abroad trip to Israel in the winter 2020 semester.

Dr. Murray received both a PhD in Toxicology and Environmental Health Sciences and an MPH in Environmental Health Sciences from the University of Maryland School of Public Health. She also holds a Bachelor of Science degree with a double major in Chemistry and Biochemistry from the University of the West Indies in Trinidad and Tobago. As a graduate student, Dr. Murray’s passion for global health took her to Sierra Leone with the student-led organization Public Health Without Borders in 2014 and 2016, where she worked with a rural community to conduct community needs assessments and health and hygiene workshops, and investigated the impact of the 2014-2016 Ebola epidemic on the community. In 2017, Dr. Murray was awarded the Lee Thornton Fellowship from the UMD Graduate School, an award which provides support to a UMD doctoral candidate who is in the latter stages of writing a dissertation that serves the public good. She is also a recipient of numerous other awards during graduate school, including the School of Public Health Dean’s Scholar Award in 2016, and was inducted into the University of Maryland’s chapter of the Delta Omega Honorary Society in Public Health.
