Statement of Research Interests:
My research program involves taking a neural systems approach to understanding the neurobiology of learning and memory. My interest focuses on investigating the principles and neural mechanisms that govern the ability to learn new rules and inhibit old rules under changing environmental conditions. The ability to adopt new strategies and inhibit old strategies involves a powerful form of plasticity for adapting to a changing environment and reflects intricate learning,memory and attentional systems. I have three main research programs that focus on understanding the neurobiology of learning and memory.

Neural Basis of Behavioral Flexibility in Frontal Cortex-Basal Ganglia Circuitry.
 One main focus of current experiments is investigating the role of the prefrontal cortex and interconnected brain regions, i.e. striatum and thalamus, in shifting strategies or learning sets. These experiments employ behavioral testing in conjunction with pharmacology and neurochemical techniques, i.e. glutamate biosensors, in understanding the dynamic neurochemical changes that occur during different forms of learning. Most recently, experiments also include functional brain imaging techniques in human subjects to understand the neural systems that support different forms of behavioral flexibility.
A defining feature of autism is restricted interests and repetitive behaviors that can be debilitating to daily living and stressful to family members. Current experiments are employing the BTBR and SHANK3 mouse models of autism to understand the neural circuitry and neurochemistry that underlies repetitive behaviors and behavioral inflexibility in autism. In addition, several studies focus on testing novel treatments that target the serotonergic or cholinergic systems to alleviate behavioral flexibility deficits. In parallel, we conduct neuropsychological studies in autistic subjects to better understand the cognitive processes that lead to cognitive inflexibility.
