My laboratory’s work focuses on the role of cell signaling during neural development, and how signaling is disrupted by genetic disorders that alter chromosomal dosage. The major focus of this work examines mouse models of 22q11 deletion syndrome, a neurodevelopmental disorder associated with psychiatric diseases. We have found that 22q11 deletion alters the development and function of cortical circuitry; our ongoing work is analyzing how 22q11 deletion alters the cell signaling events that instruct embryonic development, and the role of individual 22q11 genes in neural development. I am also the Director of the GWU Neuroscience Institute’s Biomarkers Discovery Core, a core facility that provides support for molecular and cell biological analysis of gene function in the developing and adult nervous system.
