Mostly applied maths.

I’m a Senior Data Scientist at Spotify. I build tools with probabilistic machine learning on sequences and graphs.

Personal, Miscellany


I did a PhD in Theoretical Physics at Durham. My research in Quantum Optics and Quantum Information led to the first observation of the simulton, a quasiparticle of light, in an atomic vapour. Before that, a BSc in Maths and Physics at Warwick and an MSc in Computational Physics at Stockholm.

Apart from my work I enjoy time with family, running, music and books. I also enjoy mountaineering and kayaking when I get chance.
