Bio
I'm a Senior Research Engineer at Featurespace, where we build real-time AI/ML systems for combating financial crime - a rising epidemic with links to organised crime, human trafficking, and even terrorism.
Before moving to industry, I was a research fellow at the University of St Andrews in geometric measure theory, funded by an early career fellowship from the London Mathematical Society and the Heilbronn Institute for Mathematical Research.

Teaching
I enjoy teaching and received Associate Fellowship of the Higher Education Academy (AFHEA). At the University of St Andrews, three students kindly nominated me for the 'Best Postgraduate Tutor' teaching award. I have also designed courses for and worked with The Brilliant Club and First Chances Fife to promote wider access to higher education in the UK.
