Work Experience

Professional biography

Dr. Marritt started as an Assistant Professor in the biology department in 2012 and is the program coordinator for the Pre-Health Post-Baccalaureate program.  She began teaching as an adjunct and visiting professor in 2006 and she developed a strong interest in teaching general biology.  Dr. Marritt has a passion for the health and medical sciences and continues her research in neuropharmacology.  She is involved with many of the pre-health activities in the department, including teaching anatomy and physiology and pharmacology courses.  Dr. Marritt also enjoys working with K-12 students through outreach class visits and teaching a variety of summer camps.

Academic Credentials

Ph.D., 2005, Neuropharmacology, Georgetown University Medical Center
BS, 1999, Biochemistry/Chemistry, Virginia Tech


Dr. Marritt’s research interest centers on neurobiology with a focus on the characterization of the nicotinic receptor.  The neuronal nicotinic receptor is found throughout the brain and is the receptor for the neurotransmitter acetylcholine.  The receptor is important for the development and functioning of neurological pathways.  Multiple subunits have been shown to create a number of subtypes with therapeutic importance.   Dr. Marritt’s lab is focusing on specific regions of the nervous system to characterize the nicotinic receptor.  Tissue dissection techniques are explored in rat.  Currently, the lab is investigating the vagus nerve and researching connections between the central nervous system and the enteric nervous system.
