Her research focuses on academic self-concept, motivation, STEM education, peer effects, and well-being. She has collaborated extensively with prominent scholars like Herbert W. Marsh and Philip D. Parker, producing influential work on topics such as the Big-Fish-Little-Pond Effect, gender disparities in STEM, and the psychological mechanisms underlying educational outcomes.

Her work bridges educational psychology, cross-cultural studies, and quantitative methodology. Notable contributions include analyzing reciprocal effects between self-concept and achievement, investigating gender equality paradoxes in STEM, and exploring how intercultural education impacts student well-being. She employs advanced statistical techniques like Bayesian modeling and structural equation modeling to address complex research questions.

Key areas of interest include understanding how school environments influence student outcomes, the role of parental aspirations, and the psychometric validation of scales like the Self-Compassion Scale. Her research often emphasizes longitudinal designs and cross-national comparisons, leveraging datasets such as PISA and TIMSS for global insights.

Professor Guo's work has implications for educational policy, school leadership, and bullying prevention. She advocates for evidence-based interventions to enhance student engagement and well-being while addressing systemic inequities in education.
