Jane Roberts, PhD
Principal Investigator of the USC Neurodevelopmental Disorders Lab
Dr. Jane Roberts joined the faculty at USC in 2008. She is a school psychologist who received her Ph.D. from the University of North Carolina at Chapel Hill in 1998 and spent 10 years at UNC as a research investigator and scientist at the FPG Child Development Institute. Her work focuses on understanding the biological mechanisms that underlie cognitive and behavioral functioning in children and adults with neurodevelopmental disorders such as autism, fragile X syndrome, and ADHD.
Dr. Roberts' current research focuses on:
- Early detection of autism in high risk populations: autism and fragile X syndrome
- Genetic and psychosocial contributions to mood and anxiety disorders in women with the FMR1 premutation
- Hyperarousal and stress in young children with neurodevelopmental disorders

Dr. Roberts is married, has three children, and enjoys reading and playing tennis in her spare time.
Holley (Pitts) Arnold, PhD
Assistant Scientist
Dr. Holley Pitts Arnold is an Assistant Scientist. She completed her PhD in Experimental Psychology through the University of Louisville. Holley’s work broadly focuses on understanding the cognitive, language, and socioemotional development of children who have neurodevelopmental disorders such as fragile X syndrome, Williams syndrome, and duplication 7q11.23 syndrome. Her current research focuses on investigating how early indicators of physiological and behavioral development may impact children’s everyday living skills, social communication abilities, self-regulatory skills, and psychopathology. Holley is very excited about her position at the NDD Lab and looks forward to working with the children and their families who participate in our research!

Lisa Hamrick, PhD
Research Assistant Scientist
Dr. Lisa Hamrick is a Research Assistant Scientist. Lisa worked for the NDD Lab for two years as a research assistant prior to completing her PhD in Clinical Psychology at Purdue University under the mentorship of Bridgette Kelleher (another NDD Lab alum!). Lisa’s research focuses on early social communication and language development of children at increased likelihood of autism and neurodevelopmental conditions, including children with neurogenetic syndromes such as fragile X syndrome, Down syndrome, and Angelman syndrome. Lisa is passionate about developing and utilizing assessment methods that are strengths-based and which capture the full range of abilities of children with neurodevelopmental conditions. In 2026, Lisa was awarded K23 research grant, Vocal Development and Social Communication Outcomes of Children with An Older Sibling with Autism. In her free time, Lisa enjoys playing tennis, running, scrapbooking, and spending time with husband and daughters.
