Hoyt, Catherine, PhD, OTD, OTR/L

Clinical Interests

Early intervention, 0-3 years

Research Interests

Early identification of developmental delay

Dr. Hoyt’s research focuses on identifying methods to screen children with sickle cell disease for developmental delays and developing a referral program to early intervention. With improved methods for early identification, more children can be referred to, and take advantage of, beneficial therapeutic interventions during critical years of neural development.

Teaching Roles

Case-Based Learning, guest lecturer (current); previous: Spanish for Healthcare Workers. In addition, Dr. Hoyt is a research mentor for graduate students in occupational therapy.


2019-2021: postdoctoral fellow, Washington University School of Medicine
2019: PhD in Rehabilitation and Participation Science, Washington University in St. Louis
2010: Doctorate of Occupational Therapy (OTD) Washington University School of Medicine, Program in Occupational Therapy
2007: BS in natural and social science with a secondary emphasis in Spanish, Juniata College


Dr. Hoyt is an early intervention (0-3 years) occupational therapist and Instructor at Washington University School of Medicine. A native of Silver Spring, Md., she earned her doctorate in occupational therapy in 2010 and PhD in rehabilitation and participation science in 2017 from Washington University in St. Louis. She completed a postdoctoral externship at the University of Groningen, The Netherlands, and a postdoctoral fellowship at Washington University School of Medicine. Dr. Hoyt is a co-founder of the Coalition of Occupational Therapy Advocates for Diversity (COTAD) and served as its chair from its inception in 2014 through 2020. As a clinician, Dr. Hoyt recognized the gaps in assessment, particularly for early identification of disability among children with sickle cell disease, and the real and devastating impact delayed identification of disability can have on long-term outcomes for children, leading to the development of the Infant Toddler Activity Card Sort (ITACS). She is a scholar in the Mentored Training in Implementation Science K12 Training Program and currently serves as site Co-PI for the I-ACQUIRE trial of constraint induced movement therapy for children 8-36 months of age.
