Greg Wallace, PhD, is an Associate Professor at The George Washington University. His research focuses on neuropsychological and structural brain development in autism spectrum disorder and other neurodevelopmental disorders across the lifespan and their impacts on real-world outcomes. For example, he has recently examined executive functioning profiles and their relationships to academic achievement in children and adaptive functioning in both children and young adults with autism spectrum disorder. He is also particularly interested in eating-related behaviors and their cognitive and neural correlates in typical and atypical (e.g., autism spectrum disorder) development. Dr. Wallace has published extensively and presented his work widely on these and related topics.
- Autism
- Intellectual and Developmental Disabilities
- Neuropsychology
- Brain Development
Dr. Wallace conducts several lines of work examining patient-centered, real-world outcomes and their links to behavior, cognition, and brain across the lifespan in autistic people and people with intellectual and other developmental disabilities.
Currently, Dr. Wallace and his lab are investigating:
- Mental and physical health outcomes among autistic adults, including those occurring in middle and older adulthood
- Associations of sex assigned at birth, gender, and sexual identity with brain structure and function, behavior, and health among autistic people
- Cognitive predictors of vocational and real-world outcomes among young adults with Down syndrome
- Form and function of repetitive behaviors as described by autistic youth and their families
- How autistic people compensate for challenges they experience in their daily lives
- Eating behaviors and their cognitive and health-related correlates among autistic people
