Thomas Hollenstein

Thomas Hollenstein is a Professor in the Department of Psychology at Queen's University, specializing in adolescent socioemotional development from dynamic systems and developmental psychopathology perspectives. His research examines emotion regulation dynamics, particularly shame and anxiety, using multimodal methods including psychophysiology, observational coding, and state space grid analysis.

Hollenstein investigates real-time emotion dynamics across nested time scales, emotion concordance across appraisal-expressive-physiological channels, and social influences on emotion regulation. He develops the State Space Grids software for analyzing behavioral processes and studies the impact of digital technologies on adolescent emotional development.

Recent publications address digital emotion regulation, mother-adolescent dyadic flexibility, and pandemic-related mental health changes. His work integrates developmental theory with computational methods to capture emotion system dynamics.
