Current Positions

2013-Present Associate Professor IPN, College of Veterinary Medicine, WSU, Pullman, WA


Dr. Appleyard has been working in the field of energy homeostasis for over 12 years, using both mouse
genetic and electrophysiological approaches. She has extensive experience using transgenic mouse models and in particular mouse models where EGFP (enhanced green florescent protein) is driven by promoters to identify specific neuronal populations, namely both the TH-EGFP (tyrosine hydroxylase) and POMC-EGFP (proopiomelanocortin) mouse models. She has over ten years’ experience investigating NTS function and circuitry using both electrophysiological and immunocytochemical techniques. Dr. Appleyard has over 20 years’ experience investigating signal transduction mechanisms, most recently the molecular mechanisms underlying leptin’s actions, including investigating leptin-induced dendritic spine and synapse formation. Dr. Appleyard also has experience using behavioral techniques to investigate food intake and related behaviors.

Biographical Information

Dr. Suzanne Appleyard completed a B.Sc. in Pharmacology in 1991 at the University College London in the UK. She then went on to complete a Ph.D in Pharmacology and Neurobiology in 1998 from the University of Washington in Seattle. She was a postdoctoral fellow at the Oregon Health and Science University in Portland, Oregon, which led to her appointment as a research assistant professor in the same location. She has been at Washington State University since 2007.
