Donggil SongDonggil Song is Associate Professor of Engineering Technology & Industrial Distribution, College of Engineering, Texas A&M University. His research lab (Einbrain Lab, www.einbrain.com) focuses on artificial intelligence (AI) engineering for human leaning, human-centred AI, machine learning (ML)-based mixed-reality (MR) AI systems. His research interests are geared towards creating systems by utilising AI/ML and natural language processing while focusing on facilitating human learning. Currently, his primary research includes the applications of virtual human systems in MR environments. From a methodological standpoint, his research interest has been on the synergies and integrations between AI engineering and learning technologies research methods. He holds a Ph.D. in Instructional Systems Technology from Indiana University, an M.S. in Computer Science and Engineering, and a B.A. in Religious Studies from Seoul National University (SNU), and also completed a master's program in Cognitive Science at SNU. Presently, he serves as the Managing Editor of The International Journal of Multiple Research Approaches. Read More Read Less
