Marija Maric works as an Associate Professor at the Research Institute of Child Development and Education. She studies how and for whom interventions for youth internalizing problems work. In doing so, she bridges the gap between research questions emerging from the clinical practice, and within-subject research methods to study personalized treatment effects and personalized treatment mechanisms. Dr. Maric's interests lay in the area of single-case experimental designs, both with regard to the development of these methods to study youth treatment effects as well as for education of researchers and clinicians in using these methods.

Marija Maric received her MA (2003) and her PhD (2010) from Leiden University. She completed postdoctoral program for cognitive behavioral therapist at the Dutch Association for Behavioral and Cognitive therapies (VGCt). Throughout the years she combined research work, clinical work, and teaching at the university and in the postdoctoral courses for therapists. For her work on bridging the gap between research and clinical practice she received a Wim Truijsburg award from the Dutch Association for Psychotherapy (2015). She is in possesion of BKO, SKO and Strategic Leadership for Managers certificats.
