Dhiraj Murthy is a Professor of Journalism and Media Studies (in the Moody College of Communication), Sociology (by courtesy), and School of Information (by courtesy) at the University of Texas at Austin. His research explores social media and: race/ethnicity, health, virtual organizations, and natural disasters. He employs qualitative/mixed methods and machine learning/computational methods. Dr. Murthy has edited 3 journal special issues and authored over 85 articles, book chapters, and papers; he wrote the first scholarly book about Twitter (second edition published by Polity Press, 2018). Dr. Murthy was named one of the World’s Top 2% of Scientists in Stanford University’s 2023 list for the fields of Communication & Media Studies and Sociology.

Dr. Murthy is currently funded by: the National Institutes of Health’s National Institute on Drug Abuse for a study entitled  Modified Use of e-cigarettes and Marketing on YouTube (Project Number: 1R01DA049878-01A1; $1,327,846); by the National Institute of Minority Health & Health Disparities for a study entitled Social Media, Acculturation and E-cigarette Use among Mexican American College Students in South Texas (Project Number: R01MD017280; $3,758,038), and by Good Systems at the University of Texas at Austin for a study entitled Designing Responsible AI Technologies to Curb Disinformation ($750,000). He was recently funded by the National Science Foundation’s Civil, Mechanical and Manufacturing Innovation (CMMI) Division for pioneering work on using the social media networks of journalists for  damage reconnaissance during Hurricane Florence (CMMI grant #1902460). Dr. Murthy’s work also uniquely explores the potential role of social technologies in diversity and community inclusion.

Dr. Murthy founded and directs the Computational Media Lab (Twitter feed) at UT Austin, a large lab with over 20 graduate and undergraduate students (and several high school interns). He is co-editor of the high impact journal Big Data & Society (IF=8.731). Dr. Murthy has chaired and co-chaired international social media conferences and serves on the advisory board of MediaWell, an initiative by the Social Science Research Council (SSRC).
