Dr. Ricketts is an Assistant Clinical Professor in the Department of Psychiatry and Biobehavioral Sciences at University of California, Los Angeles, where she performs research, provides clinical and research supervision, and delivers treatment. Dr. Ricketts directs the Sleep and Circadian Assessment and Intervention Lab and is a member and attending psychologist in the Child OCD, Anxiety, and Tic Disorders Program. She also serves as director of the UCLA Psychology Doctoral Practicum Training Program, and Associate Director of the UCLA Clinical Psychology Predoctoral Internship Training Program.

Dr. Ricketts received her Bachelor’s degree in Psychology from University of Florida in 2007. She then received her PhD in Clinical Psychology with a minor in Behaviorism from University of Wisconsin-Milwaukee in 2014 following completion of a clinical internship at Western Psychiatric Hospital. This was followed by completion of a National Institute of Mental Health T32 Postdoctoral Fellowship in Child Mental Health Intervention Research.  

Dr. Ricketts’ research centers on sleep and circadian disturbance and associated interventions, including novel morning light therapies (wearable short-wavelength light therapy, millisecond light flashes), experimental therapeutics (e.g., cerebral frontal thermal therapy), and cognitive-behavioral therapy in children, adolescents, and young adults with Tourette’s disorder, ADHD, obsessive-compulsive and related disorders, and anxiety disorders. Dr. Ricketts is particularly interested in the role of adolescent psychopathology in sleep. She also has emerging interests in the social, behavioral, and biological determinants of sleep health and associated interventions in non-clinical adolescent populations. Her research incorporates multimodal assessment of sleep and circadian rhythms, including self-/parent-report, sleep diary, actigraphy, spectrophotometry, pupillometry, and salivary melatonin assessment (i.e., dim light melatonin onset). She has received grant funding from a range of intramural and extramural sources (see Funding Support) for sleep and circadian research projects.
