G. John Geldhof, Ph.D.

Faculty page

Dr. Geldhof’s research focuses on the development of self-regulation across the lifespan and the relationship between intentional self-regulation and positive developmental outcomes (especially Positive Youth Development). Because of the contextualized nature of human development, he is also interested in the diverse ways thriving manifests in diverse cultural contexts.

Dr. Geldhof received his Ph.D. in Developmental and Quantitative Psychology from the University of Kansas and completed a postdoctoral fellowship in the Institute for Applied Research in Youth Development at Tufts University.

His current research program includes an emphasis on quantitative methodology, both as a tool for optimizing empirical work and as a research domain in and of itself. As a substantive topic, his quantitative research focuses on latent variable and multilevel modeling techniques.

 

Dr. Geldhof’s Current Students

Asia Thogmartin, M.S.

Asia’s research centers on the impact of contextual factors on development across the lifespan. Her experiences growing up in South Africa and working as a criminal defense investigator shape her interest in multicultural, marginalized communities. Her current work focuses on the development of critical consciousness of multicultural youth living in poverty across the U.S.

Asia earned a B.S. in Psychology with a minor in Art from Southern Oregon University and an M.S. in Human Development and Family Studies from Oregon State University. She will graduate with a Ph.D. in Human Development and Family Studies from Oregon State University in June 2021.

Whether in her academic work, her art practice, or her family life, Asia finds inspiration in the intersection of diversity, creativity, and unconventional thinking—which are critical to effective learning.

 

Yue Ni, M.A.

Yue’s research interests focus on how different levels and settings in youth’s ecological contexts, like families, youth programs, and culture, can integrate to promote positive developmental outcomes among youth. She is particularly interested in the social and emotional development of youth who might be experiencing an adjustment in a new environment, like immigrant youth in the U.S. and migrant youth in urban China.

Yue graduated from East China University of Science and Technology with a B.A. in English and received her M.A. in Applied Developmental and Educational Psychology from Boston College.

Before starting her program at OSU, she worked as a researcher at an educational technology company in Shanghai, where she developed mobile applications for family education. Prior to that, she worked with a peer-mentoring program for recent Asian immigrant youth in Quincy, MA.

Svea Olsen, Ph.D.

Svea’s interests focus on immigrant and refugee youth in the United States. Specifically, she seeks to understand how language brokering (serving as an interpreter or translator for family members or other adults) influences youth from diverse backgrounds in order to determine how schools and communities may best support them.

Svea earned her B.A. in Psychology from Lewis & Clark College with a focus on Spanish Language and Hispanic Studies. She received her M.S. in Human Development and Family Studies from Oregon State University.

Prior to coming to Oregon State, Svea worked at the Center for Emotional Intelligence at Yale University to develop, implement, and evaluate a program promoting social and emotional development among diverse learners in early childhood education settings.
