Stefanie Landeweer Jeopardy Contestant Profile

Stefanie Landeweer is a chemistry professor and environmental chemist based in Lexington Park, Maryland, appearing on Jeopardy! as a contestant from Lexington Park. Professionally, she is a Visiting Assistant Professor of Chemistry at St. Mary’s College of Maryland, where she teaches and conducts research in environmental and analytical chemistry. Her work focuses particularly on environmental contaminants of emerging concern and the use of mass spectrometry to identify and measure chemicals in environmental samples.

Landeweer’s current research is centered on UV-filter chemicals in marine environments. These compounds are commonly used in products such as sunscreens and can enter coastal waters, where their environmental behavior and potential ecological effects are still being studied. Her research involves developing and applying analytical methods capable of detecting these chemicals at very low concentrations, with the broader goal of improving environmental risk assessments.

Her academic background is strongly interdisciplinary. Landeweer earned a Bachelor of Arts in Chemistry and German from Illinois Wesleyan University in 2017 before continuing her scientific training at Florida International University. At FIU, she completed a Master of Science in Chemistry in 2022 and a Ph.D. in Environmental Chemistry in 2023. During her graduate studies, she was part of FIU’s Chemistry and Biochemistry program and was affiliated with the university’s CREST Center for Aquatic Chemistry and Environment, where she worked on research involving emerging environmental pollutants.

Her graduate research included work on the occurrence and measurement of UV-filter compounds in Biscayne National Park. She was a co-author of a peer-reviewed study examining the prevalence of selected UV-filter chemicals in the park’s waters, work that involved Florida International University researchers and the National Park Service. The project reflects her broader research interest in understanding how chemicals originating from human activity move through and persist in aquatic environments.

Landeweer has also researched the changing chemical composition of major waterways. In 2023, she presented work on monitoring spatial and temporal variation in the chemical composition of the Ohio River using non-target analysis, an analytical approach designed to detect a wide range of chemicals rather than searching only for a predetermined list of compounds. That research made use of advanced liquid chromatography and mass-spectrometry techniques.

Her research has taken her to major professional scientific meetings. During her time at FIU, she presented work at gatherings including the Society of Environmental Toxicology and Chemistry North America annual meeting, the Southeastern Regional Meeting of the American Chemical Society, and workshops devoted to emerging applications of high-resolution mass spectrometry and LC-MS/MS in environmental analysis and food safety.

Landeweer remains connected to the wider environmental-science research community through an affiliation with the University of Maryland Center for Environmental Science. Her work there continues her focus on developing dependable analytical methods for environmental contaminants, including methods for detecting multiple organic UV filters in seawater and other environmental samples.

As an educator, her principal teaching specializations are Analytical Chemistry and Environmental Chemistry. These fields closely complement her research: analytical chemistry provides the laboratory methods and instrumentation needed to identify and quantify compounds, while environmental chemistry examines what happens to those compounds once they enter natural systems. Her position at St. Mary’s College therefore combines classroom teaching with active environmental research.
