PhD Thesis
Neuroligin-3 modulates opioid-evoked changes in behavior and brain function
Undergraduate Institution and Major:

Graduate Advisor

Graduate Research
The nucleus accumbens is an important neural substrate of motivated behavior, and alterations in accumbens circuitry have been implicated in a host of human neuropsychiatric disorders ranging from addiction and drug abuse to obsessive compulsive disorder and autism spectrum disorders. I am working with Dr. Patrick Rothwell to investigate the role inhibitory synapses in controlling nucleus accumbens physiology and the behavioral effects of alterations to inhibitory signaling in this region. We are currently interested in the role of Neuroligin-3, a postsynaptic adhesion protein, in controlling structural plasticity at inhibitory synapses following exposure to drugs of abuse
