Faculty Advisor: Stephen Cowen

As a Graduate Student in Dr. Stephen Cowen's lab, I am exploring hippocampal frequencies and time cells during a skilled, fine-motor task. This project investigates the pro-cognitive effects of ketamine, and how it may enhance the neural substrates of hippocampal learning and episodic memory in rats. I also assist on a project aiming to categorize various cell types in an anesthetized and behaving Parkinsonian zebra finch model.

I earned a bachelor's degree from California State University San Marcos (CSUSM) where I studied the effects of the neuropeptide, hypocretin, on maternal depressive-like behavior in mice. I then obtained a master's degree specializing in stress response and neuropsychological test performance among young adults with and without a family history of Alzheimer's disease. I then worked as a psychological assistant administering neuropsychological batteries to patients who were experiencing memory impairment and cognitive decline. Meanwhile, I enjoyed teaching psychology courses at CSUSM and Palomar College. I am enjoying living in Tucson as I work toward my Ph.D. at the University of Arizona.
