Samer Al-khateeb is an Assistant Professor at the Department of Journalism, Media and Computing, College of Arts and Sciences, at Creighton University and a former Postdoctorate Research Fellow at the Collaboratorium for Social Media and Online Behavioral Studies (COSMOS) at the University of Arkansas at Little Rock (UA-Little Rock). He obtained his Ph.D. in Computer and Information Sciences, a master’s degree in Applied Science, and a bachelor’s degree in Computer Science form UA-Little Rock. He studies deviant acts (e.g., deviant cyber flash mobs and cyber propaganda campaigns) on social media that are conducted by deviant groups (e.g., Daesh, Black-hat hackers, and Propagandist) which aim to influence individual’s behaviors and provoke hysteria among citizens. He also studies the type of actors these deviant groups use to perform their acts, i.e., are they human (e.g., Internet trolls) or automated actors (e.g., social bots) by leveraging social science theories (e.g., thetheory of collective action), social network analysis (e.g., centralities and community detection algorithms), and social cyber forensics (e.g., metadata collection to uncover the hidden relations among these actors across platforms). He has many publications including book chapters, journal papers (e.g., Journal of Defence Strategic Communications; Journal of Digital Forensics, Security, and Law; Journal of Baltic Security; and the IARIA International Journal on Advances in Internet Technology), conferences proceedings, and conferences presentations. He won various awards such as the Staff Achievement Award for Educational Achievements, Excellence in Research Award, Outstanding Graduating Student Award (Master's Level), Who’s Who Among Students in American Universities and Colleges, the Best Paper Award, 2nd Place Most Innovative Award, and 2nd Place Societal Impact Award, among others.Dr. Nitin Agarwal is the Jerry L. Maulden-Entergy Endowed Chair and Distinguished Professor of Information Science at University of Arkansas at Little Rock. He is the founding director of the Collaboratorium for Social Media and Online Behavioral Studies (COSMOS) at UA Little Rock. His research aims to push the boundaries of our understanding of cyber social behaviors that emerge and evolve constantly in the modern information and communication platforms with applications in defense and security, health, business and marketing, finance, and education. At COSMOS, he is leading projects funded by over $10 million from an array of federal agencies including U.S. National Science Foundation, Office of Naval Research, Army Research Office, Air Force Research Lab, Defense Advanced Research Projects Agency, Department of State, and plays a significant role in the long-term partnership between UA Little Rock and the Department of Homeland Security. He developed publicly available social media mining tools, viz., Blogtrackers, YouTubeTracker,and Focal Structure Analysis used by NATO Strategic Communications and public affairs, among others. Dr. Agarwal participates in the national Tech Innovation Hub launched by the U.S. Department of State to defeat foreign based propaganda.Dr. Agarwal’s research contributions lie at the intersection of social computing, behavior-cultural modeling, collective action, social-cyber forensics, AI, data mining, and machine learning. From Saudi Arabian women's right to drive cyber campaigns to Autism awareness campaigns to ISIS' and anti-West/anti-NATO disinformation campaigns, at COSMOS, he is directing several projects that have made foundational and applicational contributions to social and computational sciences. He has published 8 books and over 150 articles in top-tier peer-reviewed forums with several best paper awards and nominations. Dr. Agarwal obtained Ph.D. from Arizona State University with outstanding dissertation recognition in 2009. He was recognized as one of 'The New Influentials: 20 In Their 20s' by Arkansas Business in 2012. He was recognized with the University-wide Faculty Excellence Award in Research and Creative Endeavors by UALR in 2015. Dr. Agarwal received the Social Media Educator of the Year Award at the 21st International Education and Technology Conference in 2015. In 2017 the Arkansas Times featured Dr. Agarwal in their special issue on "Visionary Arkansans: A Celebration of Arkansans with ideas and achievements of transformative power." Dr. Agarwal was nominated as International Academy, Research and Industry Association (IARIA) Fellow in 2017, Arkansas Academy of Computing (AAoC) Fellow in 2018, and Arkansas Research Alliance (ARA) Fellow in 2018.
