I'm a CS/ML PhD student at C4DM, where I specialize in Deep Learning for Audio. I'm also a research lead at EleutherAI. Prior to my PhD, I studied Mathematics (Algebraic Geometry) at Imperial College London (BSc, MSc). My current research interests are varied and include:

Deep Learning for Music. I've led research projects in several core areas of generative music and information retrieval including: musical foundation models (see the Aria project), self-supervised representation learning, audio transcription, and datasets. My current PhD research explores post-training techniques for pre-trained music models, aiming to improve quality control, enhance guidance and conditioning methods, and enabling applications to MIR via transfer learning.

Hybrid Audio/Language Models. I've developed a growing research interest in models that integrate audio with text or other token-based symbolic information. This includes areas such as neural audio codecs, automatic speech recognition, and audio-language models. I'm particularly interested in improving conversational speech foundation models (e.g., Moshi) through both architectural and data-centric approaches.

I'm also extremely interested in the engineering problems surrounding ML/DL. In my non-research time, I currently dedicate a portion to studying C++/CUDA. Outside of research, I have a deep love for mathematics, music production, and reading. The best part of doing a PhD is getting to learn from all kinds of people.

Aria Project

I currently lead a research project on building and scaling a transformer-based foundation model for symbolic music. The project gets its codename, Aria, from the Goldberg Variations, and has attracted generous and ongoing compute support from EleutherAI & StabilityAI. Although this project hasn't been publicly released due to publication review requirements, we are very excited to share our work in May! In the meantime, here are some early samples showcasing what it can do:

Conditioned on the initial theme
Jazz ballade interpretation of Misty
Jazz in the style of Bill Evans

These essays [1, 2] and these books [3, 4, 5] had a big influence on me.
