Kaitlyn Stepler

Assistant Professor

Department of Science

Coad Science Building
Room 303

Kaitlyn Stepler earned her Ph.D. in chemistry from Vanderbilt University in Nashville, TN under the mentorship of Dr. Renã A. S. Robinson. Her dissertation applied mass spectrometry-based proteomics—the study of all the proteins [proteome] in a cell, tissue, or organism—to investigate racial disparities in Alzheimer’s disease. She completed her postdoctoral training at the University of Maryland, College Park in May 2023, where she applied proteomics to the opposite end of the lifespan, studying embryonic development in frog and chick research models. Dr. Stepler earned her undergraduate degree in Exercise Science and Chemistry at nearby McDaniel College, in Westminster, MD.

Dr. Stepler joined the Mount in Fall 2023. Her research lab applies proteomics to understand various processes in health and disease. In the classroom, Dr. Stepler is also working to increase the exposure of undergraduate students to important analytical technologies such as mass spectrometry and proteomics.

Proteins carry out many biological processes that are essential to proper functioning of the body and may malfunction during disease states. Proteomics allows the study of these proteins on small and large scales, measuring up to thousands of proteins using high-resolution technologies such as liquid chromatography (LC) coupled with mass spectrometry (MS). Dr. Stepler’s research group seeks to apply proteomics to investigate various biological and/or analytical questions by performing wet-lab experiments and collecting new proteomics data, as well as analyzing existing rich proteomics datasets. Dr. Stepler’s group is also interested in developing new bioanalytical methods and new educational laboratory experiments for courses such as Analytical Chemistry.
