Faculty and Staff Directory

Naomi Chaytor, PhD, ABPP

Professor
Department of Community and Behavioral Health

Additional Information

She is a licensed clinical psychologist and is Board Certified in Clinical Neuropsychology by the American Board of Professional Psychology. Prior to becoming a founding faculty member in the Elson S. Floyd College of Medicine in 2015, she was a practicing clinical neuropsychologist and faculty in the departments of Neurology and Physical Medicine and Rehabilitation at UW Medicine.

Education

  • 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

Research

Her current research is focused on with the neuropsychology of 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 two NIH/NIDDK R01 grants investigating the impact of glycemic variability on fluctuations in cognitive status in adults with type 1 diabetes, and evaluating an RCT of automated insulin delivery 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).

Teaching

For the MD program, Dr. Chaytor serves in the following roles; small group facilitator and component contributer for  MEDSCHLR; Nervous System and Behavioral Health component contributor; member of the Foundations of Medicine Subcommittee. She also supervises medical student research projects and Clinical Psychology graduate students.
