John joined APR in September 2015, after obtaining a BA in Mathematics from Trinity College, Oxford. His work has taken him through Ireland, Hitchin, Telford, and Birmingham. He specialises largely in model development, but has spent some time in project management; in particular, he is very comfortable with VBA, R and SQL. John lost any skill he once had at racquet sports during lockdown, and in his spare time can be found making elaborate excuses not to go to the gym. His creativity extends to the tennis court, on which he considers himself one in a million when it comes to shanking backhands.
