ResearchGate profile

I am a Ph.D. student in the Human Development Graduate Group. My research interests are broadly in adolescent risk behaviors and mental health, particularly substance use, and influence of peer factors (e.g., prosocial peers, acceptance/rejection) and neural function, using task-based functional magnetic resonance imaging (fMRI). I also have satellite interests in prosocial behavior and contextual factors. Before joining the TEEN Lab and HDGG, I earned a Master’s in Psychological Science from the University of North Florida (advisor Dr. Jennifer Wolff), and a B.S. in Psychology as a first-generation student. I also have some background in cognitive and evolutionary psychology, as well as work experience in university administration. I enjoy traveling, hiking, photography, and spending time with my partner and our pets.

I am a Ph.D. student in the Human Development Graduate Group. My research interests are broadly in the neural underpinnings of adolescent socio-emotional development. I am particularly interested in the neural correlates of risky decision-making in adolescence, and the influence of social contextual factors (e.g., peer and family relationships). I am mainly interested in task-based fMRI paradigms, and diffusion tensor imaging. In 2016, I graduated as a first-generation college student from the State University of New York (SUNY) at Geneseo with a Bachelor’s degree in Psychology. After graduation, I worked for two years as a research assistant in Dr. Eric Nelson’s Brain and Social Development lab at Nationwide Children’s Hospital in Columbus, Ohio. From there I knew that I wanted to continue expanding my research skills and pursue doctoral work conducting fMRI research with typically developing adolescents.

I am a Ph.D. student researching the impact of adverse social contexts on the neurobiological mechanisms that underlie sociocognitive and affective functioning to subserve prosocial behaviors. I am particularly interested in the impact of discrimination, peer rejection, and chronic financial stressors on adolescent development. My current research projects are aimed at exploring adolescent autonomic and neural functioning as predictors of prosocial and empathic behavior development. I graduated from University of California, Davis in 2016 with a B.S. in Neurobiology, Physiology, and Behavior. I then obtained an M.S. in Child Development here at UC Davis, and I am excited to continue on in the HDGG doctoral program. In my spare time, I enjoy hiking, cooking, and traveling.

My current research interests lie in understanding the developmental trajectories of substance abuse and the transdiagnostic factors underlying adolescent substance abuse, anxiety and depression. In particular, inspired by my own experiences growing up in an economically depressed region of Ohio, my work with adolescents and young adults in Uganda and Morocco, and my research with adults with substance use disorders, I aim to investigate the interplay of biological and environmental routes of intergenerational transmission of substance use disorders, depression and anxiety. Within this realm, I am interested in the effects of parental socialization on adolescent emotional regulation (e.g. how parents’ patterns of reward responding affects their children’s responses to and ability to self-regulate in the face of reward) and the role these effects might play in the intergenerational transmission of substance abuse disorders.

ResearchGate Profile

Dr. Yoon completed her undergraduate degree in Psychology and Philosophy at Korea University. She then specialized in Social Neuroscience and was awarded her PhD in Psychology from Korea University. During her PhD, she led studies which implicate healthy socioemotional functioning. Specifically, with behavioral and neural measurement, she conducted projects on development of self-projective behavior provoked by social feedback, prejudice towards homosexuals, and impression management under social observation. She wants to academically help youth to reach their full potential by investigating healthy socioemotional development. Her main area of interest is the development of emotional resilience and social competency during childhood, adolescence and emerging adulthood. With multiple levels of analysis using genetic, neural, behavioral and social environmental measurement, she pursues a deeper understanding of the development of individual differences in socioemotional functioning and mental health outcomes. Dr. Yoon is a Postdoctoral Scholar and will work with data from the IDEA study with Dr. Johnna Swartz to examine patterns of brain activity associated with risk for depression in adolescents from Porto Alegre, Brazil. She will also work with the TEEN Lab on data from the Pittsburgh Girls Study.
