This essay presents digital trauma studies, a novel and interdisciplinary approach to trauma research. Digital trauma studies scrutinize the impact of technological innovation on the transmission and processing of individual and collective trauma by examining trauma-related texts and gestures produced through the digital environments. The awareness of the growing interrelations between digital media and trauma is important for acknowledging the changing role of key concepts of trauma research in the digitally mediated context and for developing a new theoretical framework for trauma studies. The conceptualization of digital mediation of trauma is also crucial for recognizing possibilities and dangers related to the deployment of big data in the area of trauma-centred research. The essay concludes with the discussion of the application of digital trauma studies framework to three areas of trauma research: the transmission of individual trauma, the pluralization of trauma discourse, and the enhancement of trauma communication by research and educational institutions.
