Current Research

The goal of our research is to understand the nature of the genetic deficits that predispose to psychiatric disorders (primarily schizophrenia) and trace the affected neural pathways. Ultimately, we would like to provide novel targets for pharmacotherapy for these disorders. Toward these goals, my lab has two interconnected research programs:

i. Genetics of Complex Psychiatric Disorders: Most psychiatric disorders have a strong genetic component and, therefore, our starting point is findings from human genetic approaches. Our genetics program has contributed a series of genetic discoveries especially on the contribution of rare mutations in the genetic architecture of complex psychiatric disorders.

ii. Animal Models of Complex Psychiatric Disorders: We are using mouse models of disease-predisposing mutations to ask what are the consequences of a genetic lesion associated with mental illness in humans, on brain structure and function of a model organism, starting at the simpler cellular and synaptic levels to the higher-order circuit and behavior levels. Implementation of a range of state-of-the-art approaches to dissect the genetic and biological complexity of psychiatric disorders is the major component of my lab and has contributed a series of recent discoveries.
