I am a research fellow applying machine learning to sound. I develop new techniques in structured "machine listening", using both machine learning and signal processing to analyse soundscapes with multiple birds. I have also worked on voice, music, birdsong and environmental soundscapes. More detail on my personal research page.

Are you interested in a PhD opportunity using machine learning / signal processing / data mining to understand natural sound? Contact me to discuss informally!
