Senior🎓
Top SchoolJohan Pauwels is a Lecturer in Audio Signal Processing based in London with 15 years of experience bridging music information retrieval, musical signal processing and machine learning. He combines academic leadership and teaching with hands-on research and software development, having held roles from postdoc to visiting researcher at institutions including Queen Mary and Imperial College. Johan is a practical open-source contributor: he improved cross-platform training workflow in CXXNet/MXNet, enhanced audio I/O and edge-case handling in madmom, and modernized UX for the webMUSHRA listening test. His background in AI and electrical engineering underpins a knack for making audio research reproducible and production-ready across platforms. He often tackles gritty compatibility and usability problems that others overlook, such as non-streamable MP4 audio handling and Likert-scale visualization improvements. Johan holds a PhD in engineering from Ghent and a postgraduate certificate in academic practice, combining rigorous research with effective teaching.
