Background: I graduated from Arizona State University in 2010 with a B.S. in Psychology. During my time at ASU, I worked in Dr. Heather Bimonte-Nelson’s memory and aging research laboratory studying the effects of estrogen and progesterone on cognitive and neurobiological endpoints using various rodent models of menopause. In summer 2010, I participated in the summer fellowship program at The Center for Neuroscience at the University of Pittsburgh (CNUP) and worked under the mentorship of Dr. Anthony Kline. Our research focused on optimizing rehabilitation treatment after traumatic brain injury. Specifically, we investigated the role of neurogenesis in environmental enrichment-mediated behavioral benefits in rats after experimental traumatic brain injury.

Current Research: I am currently a 3rd year graduate student in the Psychology department in the Behavioral Neuroscience area. I joined the Gore lab in the summer of 2011. Since joining the lab I have become interested in studying behavioral, molecular, and neuroanatomical components of social functioning. My main research focus is studying how timing and duration of estradiol (E2) treatment (relative to ovariectomy, as a model for hormone deprivation) affect social interaction and social memory. I look at the underlying molecular and cellular changes in the brain by using real-time PCR.  Tissues from the behaviorally characterized rats are used to determine effects of aging and E2 timing/duration on some of the neural circuits that underlie social behaviors. In the future I plan on using immunohistochemistry and stereological counting to assess protein expression and neuroanatomical localization. My choices of protein targets and brain regions will be determined by the most robust qPCR results. The implications of this work are relevant to all women undergoing menopause or surgical oophorectomy and may guide novel estrogen therapeutic strategies with respect to the timing and to identify the shortest possible duration to minimize risk.
