I 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). Since 2016, I have been a researcher for biosignal processing, human activity recognition, virtual reality, music information retrieval, and multidisciplinary application of AI at the Cognitive Systems Lab of the University of Bremen, where I received my Ph.D. (2021). I am co-responsible for three multipartner projects: Arthrokinemat (intelligent knee bandage), IntEL4CoRo (interactive learning for cognitive robotics), and NF-BWB (young talent development). I developed the first smart knee bandage that recognizes users' activities in real-time (Best Student Paper, BIODEVICES 2019) and proposed Motion Units, an activity modeling method with interpretability, generalizability, and expandability, rationalizing kinesiology and speech recognition knowledge into human activity research (2021). Two papers on high-level feature design (co-author) and music signal processing (first author) were the Best Paper Finalists by BIOSIGNALS 2022 and SIGMAP 2022, respectively. Seven articles for which I am the single first or/and corresponding author were marked as "Highly Cited Paper" (top 1%) and "Hot paper" (top 0.1%) by World of Science. I collected and released the 19-channel, 22-activity, 20-subject human activity dataset CSL-SHARE (2021). A dataset of ECG acquisition artifacts called sensORder was published under my guidance (2024). I received the following third-party funding and awards: the Erasmus Teaching Mobility Award (2018), the CAMPUSiDEEN Public Choice Award for advanced sensing and recognition technology (2022), and the YERUN Research Mobility Award (2022/2023). I served as a PC for 17^th BIOSIGNALS, and will be a TPC for 2^nd ArtInHCI, Pub.C. for 2^nd AIGC, as well as an AC for 33^rd ICANN and 7^th CEII. I am an editorial member of several international journals, and was awarded Sensors 2023 Outstanding Reviewer.

Recently, my international collaboration has expanded to AI for energy, assistance tool for amateur singers and exoskeletons, among others, for which a considerable number of topics are carried out in parallel. I always eagerly await new interdisciplinary and cross-border cooperation in various fields!
