Her research studies have a long-term goal of understanding the biological basis of neurodevelopmental disorders, with focus on Autism Spectrum Disorder (ASD) and Attention-Deficit/Hyperactivity Disorder (ADHD). Her current research program includes basic studies investigating the influence of gut-derived microbial molecules, such as “bacterial peptidoglycan motifs” and their sensing molecules, on brain development and behavior, and clinical studies investigating the potential role of the gut microbiota in the pathophysiology of ASD and other neurodevelopmental disorders.
