Hi, I'm Josh!

This website is a record of the projects I've worked on, some of my thoughts on things I find interesting, and what I've learned along the way.

My interests include music, good quality loose-leaf tea, free software, and space.

I graduated from the University of Oxford in 2021 with a Masters' in Computer Science. I wrote my bachelor's thesis on the security of the "CPDLC" air traffic control system; this work has since been adapted into a publication presented at AsiaCCS. My master's thesis investigated the resilience of network routing protocols in a satellite constellation when under denial-of-service attacks. Since then, I've remained at Oxford to study for my PhD, continuing my research on cybersecurity in the context of space systems.

During my time in Oxford I've been involved with a number of hackathons, travelling around the UK and beyond with Team Brewlabs. In 2019 I became Technical Director for Oxford Hack, and in 2020 I helped launch Hack Quarantine, a hackathon aimed at solving problems in the context of the COVID-19 pandemic.

I like to play the piano and clarinet — I've been playing with the Turl Street Orchestra since 2020. I've also been involved with the Oxford Computer Society for several years as well as the Christian Union — in 2018-2019 I led the St Catz Christian Union and have frequently helped to run tech behind the scenes.

If you'd like to contact me, I'm available at me@jsmailes.co.uk.
