About Me

I am currently employed as a postdoc at the University of Twente to conduct research on the professional identity development of STEM students during their school-work transitions.

I completed my PhD at Cardiff University (UK) in 2015 under supervision of Tony Manstead. In my PhD I investigated how students’ socio-economic background affects their higher education choices and their social and academic adjustment at university. From 2015 to 2018 I worked as a Research Fellow at Sussex University (UK) to conduct a RCT at 29 secondary schools to examine the impact of a self-affirmation intervention on exam grades in pupils from low socio-economic backgrounds.

I am a social psychologist, who investigates how identity and identity change processes mediate the relationships between societal and educational contexts to well-being outcomes. In my research projects I focus on social identity and identity change in adolescents and young adults in education transitions. In addition, I examine how identity processes contribute to achievement gaps between social groups.
