After obtaining an undergraduate degree in psychology (University Paris 5) and masters in cognitive science (Cogmaster), Katarina has defended her PhD in psychology at University Paris 8. She is currently a Research and Teaching Fellow and substitute lecturer at the University of Geneva.
Her research takes a cognitive and developmental perspective. Katarina's thesis is rooted in, and puts into dialogue, four complementary fields of research: conceptual development, distinction between declarative and procedural knowledge, content effects and teachers' pedagogical content knowledge. She uses experimental, quantitative methods to study the representations of teachers and students when solving arithmetic word problems in primary school. Her work articulates learning and development from the perspective of school interventions. Currently, she is pursuing parallel research on students' conceptions and teachers' conceptions.
