**Hui Liu**

Hui Liu, Dr.-Ing. is a researcher at the Cognitive Systems Lab, University of Bremen (since 2016), focusing on biosignal processing, activity recognition, virtual reality, and information retrieval. He studied electrical engineering at the Technical University of Berlin (Dipl.-Ing., 2009) and information and communication systems at Shanghai Jiao Tong University (M. Sc., 2011). He received his Ph.D. from the University of Bremen (2021). He is co-responsible for the multi-partner projects Arthrokinemat (intelligent knee bandage, finished 2019), ETAP (AI-based movement monitoring for long-term care assistance), and IntEL4CoRo (interactive learning for cognitive robotics). He developed the first wearable-based system for knee bandage that recognizes users' activities in real-time (Best Paper Award (Student Author), BIODEVICES 2019). Meanwhile, he proposed Motion Units, an activity modeling method with interpretability, generalizability, and expandability, rationalizing knowledge from kinesiology and speech recognition into activity research (2021). A 19-channel, 22-activity, 20-subject human activity dataset CSL-SHARE was collected and shared by him, on which six-hour data of an 11.52-h recording are well segmented, annotated, and post-verified (2021). His two papers on high-level feature design (co-author) and music signal processing (first author), respectively, were the Best Paper Finalists (BIOSIGNALS 2022 and SIGMAP 2022). He received the YERUN Research Mobility Award and the CAMPUSiDEEN Public Choice Award for his advanced technology study of biosignal processing and activity recognition (2022).
