Bonnie Nagel, Ph.D.

Headshot of Bonnie Nagel

Dr. Nagel is Professor of Psychiatry and Behavioral Neuroscience at Oregon Health & Science University, where she also serves as the Senior Associate Vice President for Research and Vice Chair for Research in the Department of Psychiatry. Dr. Nagel's Developmental Brain Imaging Laboratory focuses on studying adolescent brain and cognitive development in healthy and at-risk populations. Her work has primarily focused on understanding the development of executive, emotional, and reward-based networks in the brain using neuroimaging and how perturbations to these systems may result in a heightened vulnerability for mental illness during the adolescent years. More specifically, her lab has been conducting longitudinal neuroimaging studies of Portland-area youth for nearly two decades, with aims toward identifying neurobiological markers of risk and resilience for psychopathology, including addiction, depression, and suicidality, with hopes of ultimately informing more targeted intervention and prevention efforts. She is a Principal Investigator on several federally-funded National multi-site projects toward that end, including the National Consortium on Alcohol & Neurodevelopment in Adolescence (NCANDA) and the Adolescent Brain Cognitive Development Study (ABCD).

Scott Jones, Ph.D.

Scott Jones, PhD

Scott received his Bachelor’s degrees in Psychology and Biology from Kansas State University and his Ph.D. in Behavioral Neuroscience from OHSU. His work has largely focuses on modeling the trajectory of cognition and brain development in healthy and at-risk children, adolescents, and young adults. Scott’s primary interest is in developing and implementing advanced longitudinal techniques for explore neurobiological, behavioral and environmental predictors of onset and escalation of many facets of psychopathology, including substance use, mental illness and chronic pain.

Angie Morales, Ph.D.

Angie Morales, PhD

Angie is Assistant Professor in the Department of Psychiatry at Oregon Health & Science University. She obtained at B.A. in Human Biology from Stanford University and Ph.D. in Neuroscience from UCLA. After completing a postdoctoral fellowship at UCLA, Angie joined the Developmental Brain Imaging Lab in 2016. Her research career has focused on using multimodal neuroimaging techniques to identify structural, functional, and chemical biomarkers that are risk factors for future substance use or that reflect neurobiological consequences of chronic drug exposure. There is considerably variability in how individuals respond to different drugs, currently her laboratory is examining how different neurobiological responses to acute drug exposure are linked to substance use trajectories over the course of time.

Kiley Brevik

Hello! I graduated with a B.A in Psychology from Florida Atlantic University (FAU) and I am currently completing my master’s degree in Applied Psychological Sciences from Pacific University. I am interested in neuropsychology and enjoy studying and talking about the brain. My study interests circle around depression/anxiety and natural ways to reduce symptoms by targeting specific brain regions. I also have interests that include substance use, personality, and stress disorders as well as emerging therapies which utilize psychoactive chemicals. If I am not working (I work with kids) or going to school, you can find me playing outside and exploring all the nature that the PNW has to offer, with my dogs of course. I am looking forward to developing my knowledge of research and ways to overcome challenges.
