Dr. Leena Malayil is an Assistant Research Professor at the Maryland Institute for Applied Environmental Health. She is the Program Manager 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).
As part of the CONSERVE education initiatives, Dr. Malayil recently developed and directed an undergraduate summer virtual internship program for the CONSERVE Center.
Dr. Malayil is also part of the DAWN (The Dashboard for Agricultural Water Use and Nutrient Management ) Educational Team and aims to teach and inspire the next generation of leaders in sustainable agricultural water use and nutrient management by managing the Summer Internship Program and co-teaching one of the undergraduate courses.
Dr. Malayil received a PhD in Toxicology and Environmental Health Sciences from the University of Maryland School of Public Health and a Master of Science in Toxicology from the University of Georgia School of Public Health. She also holds a Master of Science in Microbiology and a Bachelor of Science degree with a triple major in Chemistry, Zoology and Microbiology from Bangalore and MangaloreUniversity, India.
Dr. Malayil's research interests lie in the fields of environmental health, food safety, water quality and human infectious diseases. For her doctoral work, she explored the metabolically-active bacterial communities in nontraditional irrigation water samples (reclaimed water, surface waters and rooftop harvested rainwater), soil and produce from the Mid-Atlantic region by coupling DNA labelling and next-generation sequencing techniques. She also evaluated culture-dependent and -independent methods to detect metabolically-active pathogenic and non-pathogenic Vibrio species in nontraditional irrigation water sources in the Mid-Atlantic region.
