Description of Graduate Research:
My lab studies the neural mechanisms of cognitive control in the context of psychiatric disease. Neuronal activity and information transfer within neural circuits are not well understood in the context of psychiatric disease. My thesis work looks at the underlying mechanisms within the thalamo-cortical network during performance of a cognitive control task to better understand how the thalamus affects cortical processing of cognition. I will also examine this network in the context of psychiatric disease and whether deep brain stimulation can reduce cognitive deficits associated with psychiatric disease.

Why Did You Choose UMN?
I chose the UMN because of the interdisciplinary nature of the program and the collaborative environment portrayed to me during the interview weekend. I also very much enjoy all the Twin Cities has to offer outside of the GPN.
