Psychology
Department: Psychiatry
I am a licensed psychologist specializing in developmental disabilities and autism spectrum disorders at The Ohio State University Wexner Medical Center. I provide psychological assessment and intervention services to support individuals and families navigating complex developmental challenges.
My patients and their families can rely on me for compassionate, evidence-based care and clear communication. I work collaboratively with a multidisciplinary team to ensure each individual receives care tailored to their unique strengths and needs.
In addition to my clinical work, I am committed to advancing education and research. I serve as a clinical professor of Psychiatry and Behavioral Health at The Ohio State University College of Medicine.
Please note: Not all physicians schedule patients at each listed location.
I have published research related to co-occurring emotional, behavioral and psychiatric disorders in those with autism spectrum disorders and other developmental disabilities as well as assessment of autism spectrum disorders. I am currently an investigator on the Nisonger Center Rehabilitation and Research Training Center on Health and Function for People with Intellectual and Developmental disabilities. The goal of my project is to identify promising practices in the treatment of psychiatric disorders in individuals with intellectual disability and to provide a research framework for future research in this area. I am also a co-investigator for the National Training Initiative to build the capacity of the workforce to meet the needs of individuals with IDD/Autism and mental health concerns.
At The Ohio State University Wexner Medical Center, we support a faculty member’s research and consulting in collaboration with medical device, research and/or drug companies because a faculty member’s expertise can guide important advancements in the practice of medicine and improve patient care. In order to provide effective management of these relationships, the University requires annual disclosures from all faculty members with external interests related to their University responsibilities.
