Hui Liu is a researcher for BME, HAR, VR, AI, MIR, and multidisciplinary application of AI at the Cognitive Systems Lab of the University of Bremen since 2016, where he received his Ph.D.. He is co-responsible for three multipartner Projects in Germany. He developed the first smart knee bandage that recognizes users' activities in real-time (Best Student Paper) and proposed Motion Units, an activity modeling method with interpretability, generalizability, and expandability, rationalizing kinesiology and speech recognition knowledge into HAR. His two papers on high-level feature design and music signal processing (first author) were the Best Paper Finalists by two European conferences. Four articles which he is the single first author or/and corresponding author were marked as "Highly Cited Papers" by WoS (top 1% of the academic field of Engineering or Biology & Biochemistry), among which one is "Hot paper" (top 0.1% of the academic field of Engineering). He published the 19-channel, 22-activity, 20-subject human activity dataset CSL-SHARE, and a dataset of ECG acquisition artifacts called sensORder was released under his guidance. He received the following third-party funding and awards: the Erasmus Teaching Mobility Award, the CAMPUSiDEEN Public Choice Award, and the YERUN Research Mobility Award. He served as a PC/TPC/AC/Pub. C. for various international conferences and an editorial member of several international journals. He was awarded Sensors 2023 Outstanding Reviewer.

He is the Principal Investigator in the European project AISYM4MED dedicated to the generation of clinical data.

Tanja Schultz was appointed Professor of Cognitive Systems at the University of Bremen in April 2015. She passed the state examination in mathematics and sports in 1989 before turning to computer science. Her diploma in 1995 was followed by a doctorate in computer science at the University of Karlsruhe in 2000. This was followed by six years as a research scientist and professor at Carnegie Mellon in Pittsburgh, PA, USA. From 2007 to 2015, she was a professor at the Karlsruhe Institute of Technology. In 2007, she founded the Cognitive Systems Lab (CSL). Her research focuses on cognitive technical systems for human–machine interaction based on language and non-verbal communication signals. To do this, she combines machine learning methods with innovations in biosignal processing, such as in “silent speech communication” and “airwriting”. In 2012, she received the Alcatel-Lucent Research Prize for her overall work in the field of “Humans and Technology in Communication Systems.” At the University of Bremen, she is a computer scientist and set up the Biosignals Laboratory.
