Dr. Kathleen Beullens (PhD, 2009) is associate professor and research director of the Leuven School for Mass Communication Research (KU Leuven, Belgium). Her research focuses on the (longitudinal) effects of different media uses (e.g., television, social media, video games, mobile phones) on children’s and adolescents’ psychosocial well-being. As a researcher in media psychology, she aims to unravel the processes through which various forms of (social)media use are associated with health and risk-related outcomes (including alcohol use, smoking). In addition, she examines the context of children's ubiquitous screen media use and its impact on peer and parental relations. Her work has so far resulted in more than 70 international peer-reviewed articles, book chapters, and conference presentations, and received multiple awards. On top of her research activities, Beullens teaches multiple courses in the bachelor and master of communication sciences and the master of business communication at KU Leuven.
