Peixoto’s lab focuses on using genomic and computational biology approaches to study brain function. In particular we are interested in understanding the underlying molecular basis of Autism Spectrum Disorders and their comorbidity with Intellectual Disability and Sleep Impairments. The lab uses mouse models for functional genomic studies of behavior and patient samples to study genetic contributions to disease.
