About me
I am a PhD student at the University of Oxford, supervised by Prof. Wes Armour and Prof. Rodrigo Bruno. My research interests include cloud computing, high-performance computing, and distributed systems. Before joining Oxford, I obtained an MPhil in Advanced Computer Science from the University of Cambridge and an MEng in Computing Science from the University of Aberdeen.
