Professional Statement
Neurodevelopmental and neuropsychiatric disorders encompass highly prevalent conditions such as intellectual disability, epilepsy, autism, schizophrenia, and other psychiatric disorders. Imbalance of inhibitory and excitatory neuronal signaling has been found in association with many of these disorders, suggesting there are common underlying disease mechanisms that contribute to cortical and cerebellar dysfunction. These disease mechanisms can be elucidated through in-depth dissection of well-defined single gene neurodevelopmental and neuropsychiatric disorders such as the EBF3-related Hypotonia, Ataxia, and Delayed Development (HADD) syndrome and EIF2AK2-related Leukoencephalopathy, Delayed Development, and Episodic Neurologic Regression (LEUDEN) syndrome.The Chao laboratory combines synergistic cross-species approaches in genetically engineered fruit fly and mouse models with human clinical studies and collaborative efforts with the Undiagnosed Diseases Network to investigate the genetic, developmental, and neurophysiological basis of neurodevelopmental and psychiatric disorders. A wide variety of approaches and techniques are employed in our laboratory including RNA, exome, and genome sequencing; development of genetically engineered fly and mouse models; structural and functional analysis with electrophysiology; confocal, rodent MRI, and super-resolution imaging; molecular and cellular assays; and comprehensive behavioral profiling in animal models. Our goal is to determine the genetic and neurobiological basis of cerebellar and cortical excitatory and inhibitory neuronal signaling in both health and disease.
