Jules Drean's Mugshot

I am a 6th year PhD student at at MIT CSAIL, co-advised by Srini Devadas. and Mengjia Yan. Simply put, I build computers and systems that have interesting security properties.

More specifically, my research intersects trusted hardware, applied cryptography and micro-architectural side channels.

These days, I've been working on combining secure hardware and multi-party computation for private data processing, building trusted execution environments secure against transient executions attacks, devising isolation mechanisms for confidentially training large language models in machine clusters, and developing embedded devices that can create virtual objects with a property of authenticity. You can find a more detailed description of some of my current projects here.

For a less technical description of my work: I build big computers that can do machine learning tasks for you privately, normal sized computers that can secure sensitive computation from their own operating system, and little computers that can prove the work they did to each others.

Before coming at MIT, I was an undergrad and a master student at Télécom Paris where I obtained my "Diplome d'Ingenieur" while studying embedded systems and theoretical computer science. In order to prepare for the national exam to French engineering schools, I spent two years in Classes Préparatoires at Lycee Henri IV where I mainly studied mathematics and physics.

I am originally from Brittany, in the French countryside. I grew up in Lorient where I was a ballet dancer at the Regional Conservatory for more eleven years. On my free time, I enjoy practicing digital photography that I picked up after following a few excellent classes online. I also cook and bake almost everyday. I love swimming and running and this semester I've started training in Muay Thai and Brazilian Jui-Juitsu.
