Research Interests:

Neural circuit formation during development is fundamentally important for brain functions and requires precise regulation of many cellular processes, including neuronal migration, axon targeting, and synapse formation. Miswiring of neural networks underlies many neurological and psychiatric disorders, including intellectual and learning deficits, autism, addiction, and neurodegeneration. Our research aims to understand temporal and spatial regulation of cell signaling that ensures the accuracy of neuronal connections. The main questions we are pursuing include 1) how is cell signaling dynamically controlled as neurons/axons navigate through environs and 2) how alterations in neural circuitry contribute to disorders such as autism and drug addiction. We utilize a variety of approaches, including genetic mouse models, imaging, molecular and biochemical studies, and behavioral assays to address our questions.
