Emily serves as Public Health Laboratory Scientist within the Laboratories Administration of the Maryland Department of Health. She is an integral part of a team of scientists spread across three laboratories and thirteen specialty laboratory sections.

She is also responsible for testing water samples collected from streams and public beaches to determine the presence of E. coli. 

The Laboratories Administration, situated within the Maryland Department of Health, provides diagnostic and reference services to hospitals in Maryland while offering support to local health departments. Additionally, the approximately 230 scientists and support staff within the department conduct environmental testing, which plays a crucial role in safeguarding the health of Maryland citizens. This testing not only contributes to the enforcement of federal regulations such as the Federal Food and Drug Act, Chesapeake Bay Program, Pasteurized Milk Ordinance, and the Federal Safe Drinking and Clean Water Acts but also helps ensure the quality of consumer products.
