My research interests are in the fields of music informatics (music information retrieval), computer music, music signal processing, digital audio, artificial intelligence and music cognition. In recent years I have mainly worked on the extraction of musical content from audio signals, with a focus on rhythm, harmony and intonation. For example, I have worked on beat tracking, audio alignment, chord and note transcription, and singing intonation, using signal processing approaches, probabilistic models, and deep learning.
