About me

Before joining the CDT I was an electronics engineer working for Arm for over a decade. I led some big teams building Neural network Processing Units and I’ve come back to academia to explore how ML technology can be applied in agriculture. There’s a crunch coming up in the next couple of decades between population, climate change and biodiversity and I believe improving agricultural efficiency is a big part of how we can get through that. I’ve also had various placements and consultancy roles including keeping BBC Alba on air in Glasgow, working for Hitachi in Japan, designing control electronics for a telecoms start up and developing a drug delivery device for arthritis patients. I’ll be studying my PhD in the plant sciences department in Cambridge in cooperation with Defra. I also enjoy running, climbing and cooking.

MSc Project

Improved Control of Invasive Plant Disease Epidemics Using Partially Observable Markov Decision Processes

Invasive plant diseases cause damage to agricultural crops and ecosystems. However, growers and policy makers have limited resources for control of any given epidemic and collecting information about epidemic status can be expensive. Partially Observable MDPs (POMDPs) are used to model sequential decision making problems where the agent has only partial information about the situation. This project will explore application of POMDP techniques to plant disease epidemics by building a compartment based epidemic model and measuring the effectiveness of epidemic control against a simple, heuristic-based agent.
