Stefanos Mastrotheodoros

Stefanos Mastrotheodoros serves as Assistant Professor of Developmental Psychology at the University of Crete since 2022 and concurrently holds a Postdoctoral Researcher position at Utrecht University (Netherlands) from 2020 to present. His prior roles include Doctoral Researcher at Utrecht University (2015-2020) and Research/Teaching Assistant at the National Kapodistrian University of Athens (2010-2015).

His educational background includes:

• Psychology degree from National Kapodistrian University of Athens (NKUA)
• 3-year Master of Science in Clinical Psychology from NKUA
• Ph.D. in Psychology from NKUA (2015) focusing on adolescent identity development

Dr. Mastrotheodoros investigates psychosocial development and family relationship dynamics during adolescence, with emphasis on how parent-adolescent relationships evolve, marital conflict impacts parenting, and personal/ethnic/national identities form—particularly among immigrant youth. His work examines intra-family processes through longitudinal and daily diary methodologies to capture micro-level fluctuations.

Analysis of his 2017-2021 publications reveals consistent focus on family systems and identity development. Key patterns include conflict spillover mechanisms from marital to parent-adolescent relationships, identity formation in multicultural contexts, and methodological innovations in measuring adolescent perceptions. His research frequently employs multi-informant designs to dissect daily family interactions and cross-cultural identity processes.
