Summary Statement of Research Interests
Dr. Williams’ research focuses on infant-family and early childhood mental health, and on diagnosis and assessment of autism spectrum disorders. She is currently Co-Investigator for a multi-site NIH-funded Autism Center of Excellence studying early biomarkers of autism in infants with tuberous sclerosis complex (Principal Investigators are Mustafa Sahin, MD from Boston Children’s Hospital and Darcy Krueger, MD from Cincinnati Children’s Hospital). She has participated in studies of innovative assessment and intervention approaches for children with ASD, including a study of autism in children with vision impairments (with Mark Borchert, MD and Cassandra Fink, MPH), a study of sensory adaptations to the dental environment for children with ASD (with Co-PIs Sharon Cermak, PhD and Jose Polido, DD), and studies of novel technological approaches to the study of social interactions in autism (with Shri Narayanan, PhD). In the area of infant-family mental health and developmental disability, Dr. Williams has participated in studies of modifications to evidence-based mental health treatments for young children with developmental disabilities, access to mental health care for infants in the foster care system, and studies regarding developmental screening in young children from underserved communities.
