Dr. Porcelli was born and raised in New Jersey. He received his Ph.D. in Psychology from Rutgers University and Master’s degrees from Rutgers University and New York University. He most recently served as a postdoctoral fellow at the Social and Affective Neuroscience Lab at Rutgers University. His research addresses the neuroscience of stress, decision making, reward processing, and memory. His research has been supported by a Busch Biomedical Research Grant, and has received welcomed media attention in such publications as The Economist and the APA Observer.

Dr. Porcelli has taught a number of courses including Biopsychology, Research Methods, Advanced Graduate Statistics, Introductory Psychology, and the Psychology of Learning. As he extends his coursework at Marquette he intends to develop additional undergraduate and graduate level courses along his stated areas of interest (e.g., stress and decision-making).
Dr. Porcelli will not be accepting graduate students in the 2015-2016 or 2016-2017 academic cycles.
Dr. Porcelli’s research utilizes a combination of behavioral, psychophysiological, and neuroimaging methodologies to examine the influence of stress exposure on decision making, reward processing, and memory in humans. He will be extending this line of research at Marquette with a particular focus on the neural correlates stress-related modulation of risk-taking, the role of stress in the development and expression of habitual behaviors, the manner in which acutely stressful states transition into states of chronic stress over time (as in post-traumatic stress disorder), and how exposure to stress may be related to development of (or relapse in) drug addiction. His long-term objectives involve moving towards a solid scientific understanding of the foundations of the relationship between stress, physiology, and behavior while also developing techniques that can be used to intervene to mediate the negative effects of stress exposure (or promote its positive effects).
As a research assistant in the lab, your responsibilities would include: (a) working with human research participants and implementing experiments involving them (some of which involve stress exposure, requiring you to become very familiar with a set of important safety regulations), (b) becoming familiar with the use of skin conductance recording equipment and the scoring of skin conductance data, (c) learning to acquire salivary cortisol measurements, and (d) at more advanced levels analysis of behavioral data. Typically, working directly in the fMRI environment is restricted to graduate students. That said, I am willing to make exceptions on that is an undergraduate research assistant is with me long enough and demonstrates an interest in that area as well as the aptitude necessary for learning such advanced techniques.
