My 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.


Dr. Peixoto is the faculty adviser from the College of Medicine to the WSU Spokane Genomics Core.

She is also a member of the International Society for Autism Research (INSAR), The Society for Neuroscience (SFN) and the International Society for Computational Biology (ISCB).
