Members
Lenka Dědková, Ph.D., is a postdoc researcher and a department vice-head at IRTIS. She also serves as an assistant professor in the Department of Media Studies and Journalism (Faculty of Social Studies, Masaryk University), and fulfills the role of managing and associate editor for Cyberpsychology: Journal of Psychosocial Research on Cyberspace.
Lenka has extensive experience in conducting both quantitative and qualitative social science research. She recently led the nationwide longitudinal data collection on parent-child dyads and is currently heading a working group on the long-term impact of ICT on children and adolescents. Throughout her career, Lenka has contributed to various national and international research projects, including those funded, for instance, by Horizon 2020 Research & Innovation programs. She is an active participant in the EU Kids Online research network and regularly attends international meetings and conferences such as ECREA and EARA.
Lenka's interdisciplinary approach to research incorporates her expertise in psychology, communication, and informatics. Her primary research interests revolve around the role of parents in children's and adolescents' ICT usage patterns. For example, she examines parents' perceptions about their children's ICT use, including what they consider beneficial and what concerns them. She also studies parental mediation strategies and their effects on children's online behavior, as well as the impact of children's and adolescents' experiences with online interactions on their well-being, or usable security.
Lenka has had her research published in numerous peer-reviewed journals such as Information, Communication & Society, New Media & Society, or Journal of Family Issues. She has also written several book chapters, most notably in The Routledge International Handbook of Children, Adolescents and Media. In recognition of her contributions to the influential EU Kids Online 2020 report, she was honored with the MUNI Scientist Award in 2020.
