Emma Ste. Marie

  • Assistant Professor


Dr. Emma Ste. Marie. earned her B.S. in Chemistry from Emmanuel College (Boston, MA) and her Ph.D. in Chemistry from the University of Vermont (Burlington, VT). After completing a postdoctoral fellowship at Boston College, she joined Norwich University’s faculty in 2021 as an Assistant Professor. Ste. Marie teaches organic chemistry lecture and lab, and senior synthesis/research courses.

Ste. Marie’s research lies at the intersection of chemistry and biology, and aims to synthesize chemical tools that can be used to solve biological problems. She is interested in peptides that have unique biological activities, antioxidant peptides, incorporation of non-natural amino acids into peptides, and synthesis of novel amino acids. In addition, Ste. Marie is always open to exploring new project ideas generated by students. She has served as a mentor for numerous student-lead research projects, including: the synthesis of biodiesel from algae, water quality testing in local rivers, and the binding of fungal biomolecules to heavy metals.

Awards and Grants

Ste. Marie is dedicated to conducting interdisciplinary research at Norwich University, and has been awarded multiple grants from the Vermont Biomedical Research Network (VBRN) to support her work. Ste. Marie was granted a $10,000 Startup Award in 2021, and was granted a $25,000 Pilot Award in 2023 from VBRN. Ste. Marie is a member of the VBRN bioorganic thematic group where she collaborates with other faculty members throughout Vermont.

Research Interests and Expertise

With her research, Ste. Marie’s aims to develop and use chemical tools to solve biological problems. She is particularly interested in peptides equipped with nonnatural amino acids that have unique biological activities. Other research interests include designing conformational switch peptides, incorporating redox active amino acids cysteine and selenocysteine (and their derivatives) into peptides, and designing peptide therapeutics with enhanced pharmacological properties.
