Postdoctoral Researchers

Jeremy Harper, PhD.

Jeremy is a postdoctoral fellow on the National Institute of Drug Abuse T32 in the University of Minnesota Department of Psychiatry. A native Floridian, he earned a Bachelor of Science with honors in psychology and minors in statistics and religion from Florida State University in 2012. In 2020, he completed his clinical internship at the University of Illinois at Chicago, and received his doctorate in Clinical Science and Psychopathology Research at the University of Minnesota while training at the Minnesota Center for Twin and Family Research.
The broad aim of his research involves testing how biobehavioral correlates of cognitive control, impulse regulation, and executive functioning reflect the risk for, and consequence of, substance misuse and other disinhibitory behaviors in adolescence through young adulthood. He approaches these research questions by applying his expertise in EEG-based cognitive neuroscience, behavioral genetics, and dimensional psychopathology.

Jonathan Schaefer, PhD.

Dr. Schaefer is a Postdoctoral Research Associate at the University of Minnesota’s Institute of Child Development. He graduated with Highest Honors in Psychology from Swarthmore College in 2011. Subsequently, he completed post-baccalaureate research training at the National Institute of Mental Health, graduate training in Clinical Psychology at Duke University, and clinical internship at the Minneapolis VA. Dr. Schaefer’s research centers on (1) understanding why some individuals develop mental health problems following exposure to stress or adversity whereas others remain resilient, as well as (2) identifying the mechanisms through which these experiences “get under the skin” and influence mental and physical health. His work is explicitly multi-modal and multidisciplinary, drawing on tools and approaches from developmental psychopathology, neuropsychology, psychiatric epidemiology, and behavioral genetics.
