Short bio

I studied Psychology at the National Kapodistrian University of Athens (NKUA), in Athens, Greece; then I completed the 3-year Master of Science degree in Clinical Psychology at the NKUA; I completed my Ph.D. at the Department of Psychology at the NKUA in 2015 studying the development of personal identity during adolescence. From 2015 to 2020 I worked as a doctoral researcher (doing a second Ph.D.) and thereafter as a postdoctoral researcher at the Department of Youth and Family, at Utrecht University, in Utrecht, the Netherlands. My research interests revolve around psychosocial development and family relationships during adolescence.

Research

My research interests revolve around psychosocial development and family relationships during adolescence. In my studies, I examine questions such as how do parent-adolescent relationships change during adolescence? How do marital relationships affect parent-child relationships during adolescence? What factors are implicated in the process of personal identity development?
