Hi, I'm Josh! I'm a postdoctoral researcher at the University of Oxford, working with the Systems Security Lab on research in cyber-physical systems security, with a particular focus on authentication and security in satellite communication. I'm also a Career Development Research Fellow at St John's College, Oxford, where I teach undergraduate students.

This website serves as a record of papers I've published, past projects I've worked on, and a few blog posts on things I find interesting.

My research interests lie in the field of cyber-physical system security, with a particular focus on improving the security of satellite communication. My current research is in the following areas: using transmitter fingerprints to detect and mitigate attacks at the physical layer, using network simulation to improve the security of protocols in large-scale satellite networks, and monitoring satellite communication at the physical layer. More details on my research can be found at my department page.

My personal interests include music, quality loose-leaf tea, good coffee, free software, and space. During my time as a student I was involved in a number of hackathons, travelling around the UK and beyond; some of the projects we created are described on my projects page. In 2019 I helped to organise the Oxford Hack event as Technical Director, and in 2020 I was involved in launching Hack Quarantine, a hackathon aimed at solving problems in the context of the COVID-19 pandemic, attended by over 3,500 people.
