Dr. Ashwin Tudur Sadashiva is a Research Scientist at the Institute for Software Integrated Systems (ISIS) and an Adjunct Assistant Professor in the Department of Computer Science, College of Connected Computing, Vanderbilt University. His research develops human-centered AI that senses, models, and supports learning, combining computer vision, speech and language processing, and generative AI to study how students engage, regulate their learning, and collaborate. His work spans four areas: multimodal learning analytics and affective computing; responsible AI in education, including privacy-preserving de-identification and fairness auditing of emotion recognition models used in K-12 classrooms; AI for mixed-reality training and simulation; and the release of public multimodal datasets and open-source tools for the research community. Dr. Tudur Sadashiva is Co-Principal Investigator on a U.S. Department of Defense project evaluating teamwork in mixed-reality training environments, and contributes as senior personnel to the NSF AI Institute for an AI-Engaged Future of Learning (Engage AI) and the IES-funded GENIUS initiative. He has authored more than 100 peer-reviewed publications, received Best Paper Awards and multiple Best Paper Nominations at venues including AIED, ICCE, I/ITSEC and IEEE TALE, and holds a granted patent. He serves as an Associate Editor for the Cureus Journal of Computer Science, chairs the APSCE Special Interest Group on Learning Analytics and Educational Data Mining, has organized workshops at AIED, EDM and ICCE, and has served on National Science Foundation review panels.
