Faculty and Staff Directory


Associate Professor

Dr. Chaytor is an Associate Professor in the Department of Medical Education and Clinical Sciences. Prior to becoming a founding faculty member in the Elson S. Floyd College of Medicine in 2015, she was a practicing clinical neuropsychologist and Assistant Professor in the departments of Neurology and Physical Medicine and Rehabilitation at UW Medicine. She is Board Certified in Clinical Neuropsychology by the American Board of Professional Psychology.


  • BSc (Honours), with distinction, University of Victoria
  • PhD, Clinical Psychology, Washington State University
  • Predoctoral Internship, Clinical Neuropsychology, Baylor College of Medicine
  • Postdoctoral Fellowship, Clinical Neuropsychology and Rehabilitation Psychology, University of Washington School of Medicine


Her current research is focused on cognition in adults with type 1 diabetes, including 1) glycemic variability and cognitive performance, 2) the relationships between cognitive performance and diabetes self-management behaviors, and 3) cognitive, quality of life and emotional correlates of medical technology use (e.g., artificial pancreas, continuous glucose monitoring). She is currently a Principal Investigator on an NIH/NIDDK R01 investigating the impact of glycemic variability on fluctuations in cognitive status in adults with type 1 diabetes, and a foundation grant evaluating an RCT of continuous glucose monitoring in older adults with type 1 diabetes.

In addition, she is interested in the use of cognition as a mediator/moderator of outcomes in clinical trials and the use of mobile phones to collect neuropsychological data in clinical research. Previous work has included projects evaluating the validity of mobile cognitive assessment, testing the effectiveness of depression treatment in adults with epilepsy, characterizing neuropsychological and emotional functioning in epilepsy and psychogenic nonepileptic events, and improving neuropsychological prediction of real-world outcomes (i.e., ecological validity).


For the MD program, Dr. Chaytor serves in the following roles; teaching faculty member for the year-long Evidence-Based Medicine (EBM) longitudinal component in year 1; Nervous System and Behavioral Health component contributor; member of the Scholarly Projects Committee. She also teaches an annual didactic series on neuropsychology for the Providence Psychiatry Residency program.
