One of his recent papers on social media addiction entitled “Explicating problematic social network sites use: A review of concepts, theoretical frameworks, and future directions for communication theorizing” has been awarded the Best Published Article Award 2019 by the Children, Adolescents, and Media Division at the International Communication Association.
