Research Interests
My research interest is situated at the intersection of interplay between individual and context, methodology, and prevention/intervention. I am passionate about applying innovative methods to investigate how the transactional dynamic processes between individuals and their developmental contexts foster positive development (e.g. individual strength and competence, relationship health, ​optimal well-being, upward developmental trajectory, and resilience), and how to apply such knowledge and advanced methods to inform intervention for promoting individual well-being in real life.
Substantively, I am interested in understanding individual positive development from a dynamic-focused, system-oriented, and strength-based perspective, by identifying positive assets and processes in interpersonal contexts (e.g., in family systems, friend and peer relationships, romantic relationships, and social interaction in general). My research focuses on how they may accumulate or change over time (e.g., momentarily, daily, yearly) and interact with broader ecological contexts (e.g., school, community, culture).
​
Methodologically, I am interested in 1) mixture modeling (e.g. LCA, LPA, LTA) from person-centered approach that acknowledges individual differences, 2) multilevel modeling (MLM) that accounts for factors from different levels of contexts, 3) time-varying effect modeling (TVEM) that enables the estimation of dynamic associations across time, and 4) structural equation modeling (SEM) and dynamic system modeling (DSM) that capture transactional process and system dynamics in complex data structure.

The Team

Lab Coordinator
Caleb Coates
Hello! My name is Caleb and I am the lab coordinator for the DREAMS Lab at ASU. I received my undergraduate degree in neurobiology from UC Irvine, and my research interests include sleep, language dominance and diversity, and cognitive aging over the lifetime. In my free time, I love playing with my dog, hiking and rock climbing, building Legos, and watching movies.

Postdoctoral Research Scholar
Yuan Zhang, Ph.D.
Yuan Zhang is a post-doctoral research scholar in the DREAMS Lab. She earned her Ph.D. in Human Development and Family Sciences from the University of Connecticut. Her research interests include parenting and parent-child relationships across cultural contexts, with a focus on how these dynamics shape the development of children and adolescents. Her work also extends to the well-being and mental health of historically minority populations, including ethnic and racial minority communities, immigrant families, and LGBTQ+ individuals. Yuan explores potential protective factors within various ecological systems—such as neighborhoods, families, peer groups, and individual characteristics—to understand how these influences can buffer against adverse outcomes and promote resilience. When she is free, Yuan loves
to bake and cook, as well as go hiking.
