Dr. Xiang LI is an Associate Professor of Computer Science at the University of Aizu, Japan. He received his Ph.D. in Mechanical Engineering from Xi’an Jiaotong University, China, in 2015, and conducted postdoctoral research at the University of Aizu from 2016 to 2018. His research initially centered on signal processing and sensor networks, particularly in Structural Health Monitoring (SHM) and the Internet of Things (IoT). In recent years, his interests have expanded to artificial intelligence (AI) and cognitive science, with emphasis on sparse representation, large language models (LLMs), hand pose, facial expression, and character voice for interactive applications. He has published extensively in peer-reviewed journals and conferences, contributing to both theoretical advancements and practical system development. Dr. Li is a member of IEEE and has received multiple research grants for his interdisciplinary work bridging signal processing, AI, and engineering.
