Co-Investigators

Dr. Jeffrey Spielberg is Assistant Professor in the Department of Psychological and Brain Sciences at the University of Delaware. His research seeks to identify and understand the manner in which brain connections become disturbed in pathological anxiety (e.g., PTSD, worry) and mood (e.g., depression, bipolar), with a particular focus on the circuitry supporting two processes central to pursuing goals – motivation and executive function. He examines these circuits in both healthy and at-risk adults and adolescents. The aim of his developmental work is to identify neuromaturational changes that give rise to the increased risk for psychopathology observed in adolescence. In this work, his is particularly interested in the contribution of pubertal factors (e.g., testosterone) and how related individual differences may place children at greater risk for pathology. He collaborates closely with the PD lab on our neuroimaging projects. Email: jmsp@udel.edu

Graduate Students

Rickie Miglin is a Clinical Science graduate student in the PD Lab. She received her B.S. in Psychology from Drexel University in 2015, where she conducted research in Dr. Nezu’s Stress and Coping Lab. Following graduation, she worked as a research assistant in the Center for Interdisciplinary Research on Nicotine Addiction at the University of Pennsylvania. She then received a post-bac Intramural Research Training Award and gained experience with fMRI research at the Neuroimaging Research Branch of NIDA’s Intramural Program. She is interested broadly in the factors that influence impulsive behavior (e.g., problematic substance use) including stress, neural mechanisms, and cognitive processes (such as decision-making). She was recently awarded a two-year National Research Service Award (F31) Fellowship from the National Institute of Drug Abuse.
