about
I am a passionate researcher based in Shanghai, working at audio signal processing, bioacoustics, machine learning and computer music. I graduated from Queen Mary University of London (QMUL) in 2023. As co-founder of the Mountaineering Acoustics Network (MAN) nonprofit initiative, I develop AI-driven solutions for acoustic analysis and environmental sound understanding.
My work spans from developing neural audio codecs for geophone recordings to creating experimental electroacoustic compositions. I have conducted field recording expeditions across China, the UK, France, and Switzerland since 2023, capturing the acoustic ecology of high-altitude environments.
research interests
- Audio Signal Processing & ML/AI: Digital signal processing, spectral analysis, audio feature extraction, neural audio synthesis
- Computational Bioacoustics: Soundscapes study, sound event detection
- Computer Music Research: Philosophy of sound
research
Captured ecological soundscapes using equipment from interharmonics Wien. Built annotation workflow for soundscape corpus. Trained EnCodec-based neural audio codec with Transformer for ultra-low bitrate compression.
Developed two-stage anonymisation system combining McAdams coefficient DSP and VAE-GAN timbre transfer. Trained on Flickr 8k Audio Caption Corpus. Integrated into ZEBRA framework with improved EER and voice distinctiveness metrics.
