Education and Training

  • The University of Georgia, 2010
    Bachelor of Science in Chemistry

    Doctor of Philosophy of Pharmacology and Neuroscience
  • The University of Maryland, Baltimore, 2016-2018
    Postdoctoral Fellowship


Dr. Shannon Dunn received a B.S. (Chemistry) from The University of Georgia in 2010, followed by a Ph.D. (Pharmacology and Neuroscience) from Texas Tech University Health Sciences Center in 2016. During her doctoral research, she studied the effect of thioredoxin (Trx), a redox-damage repair protein that aids cells to recover from an oxidative state, damaging-deficiency in onset of diabetes. Her dissertation details the creation and characterization of novel mouse models of T2D, including transgenic and aged mice on diets with elevated fat and sugar content. Dr. Dunn has a broad background in Pharmacology, with training in Endocrinology and Diabetes. Her first postdoctoral fellowship is at the University of Maryland working with Dr. Simeon Taylor to explore the role of DYRK1B in cardiometabolic physiology. She plans to investigate the effects of Dyrk1B-catalyzed phosphorylation of transcription factors such as FOXO1.

Research/Clinical Keywords

Research Interests

Shannon's research interests includes the effects of western diet on vascular function in mice with a type 2 diabetes phenotype, obesity and metabolic syndrome, high fat diet-induced oxidative stress, and the exacerbating effects of high fat diet and aging on the vasculature.
