Welcome to CienciaPR, an expert and resource network for all who are interested in science and Puerto Rico.
I received my PhD in Psychology (Focus on Behavioral Neuroscience) from the University of Puerto Rico in Rio Piedras, where I worked with Dr. Gregory Quirk studying the neural circuits of fear and avoidance learning. I then completed my postdoctoral training with Dr. Garret Stuber at UNC Chapel Hill where I studied the neural circuits of arousal and motivation. I'm currently a principal investigator in the Department of Psychiatry, the Department of Cell Biology and Physiology, the Neuroscience Center, and the Carolina Institute for Developmental Disorders at UNC Chapel Hill. I also Co-Direct the Carolina Stress Initiative and I'm the Assistant Director of the Intellectual and Developmental Disorders Research Center.
Psychiatric disorders are often characterized by rapid and amplified arousal response to stimuli (hyperarousal), which is often followed by a motivational drive to avoid such stimuli. My lab uses animal models to shed light on the relationship between arousal and its underlying neural substrates.
