    Who am I?

    My name is Pablo Rauzy, but I also go by p4bl0, mostly when I'm not away from keyboard. I'm an associate professor of computer science at Université Paris 8 – Vincennes à Saint-Denis, where I'm teaching many different topics to computer science and geopolitics students. I'm also the head of our computer science licence degree. In addition to technical skills, I try my best to give our students a critical perspective on technologies and raise their awareness about their social role as future developers. My research takes place in the PASTIS team and focuses on emancipatory security and privacy. That is, security that serves the people rather than companies or states. I'm one of the founder of the Upsilon project. I'm also taking part in the Géode project and the GdR CIS. These days my most of my research activity concerns the limits of blockchains. Apart from my life as an associate professor, I also handle sounds and lights for La Corde sensible, an awesome theater company. This is me with a giant ladle on my head, and here is a more recent picture.

    Academic background

    Before my current position at Paris 8, in 2015–2016, I spent a year as a post-doctoral researcher in the Privatics research team of Inria, at the CITI lab in Lyon, France. There I was working with Daniel Le Métayer on formal model for privacy as control.

    Before my post-doc, from 2012 to 2015, I was a PhD student in the SEN research group of the COMELEC department at Telecom ParisTech. My advisor was Sylvain Guilley. I was working on formal software methods for cryptosystems implementation security, against side channel and fault injection attacks. I was also teaching at Polytech'UPMC.

    Before starting my PhD, from 2009 to 2012, I was studying at the Computer Science department of the École normale supérieure de la rue d'Ulm, where I graduated from the Parisian Master of Research in Computer Science.

    Before studying at the ENS, from 2007 to 2009, I was a Mathematics and Computer Science student for two years at Luminy's Faculty for Sciences, which is a part of the University of the Mediterranean.

    More about me

    I am an activist. The political movement which best fits my views and ideals is anarcho-communism, as I see both freedom and equality as fundamental and inseparable. The UCL manifesto (in French) is a good read to learn more about this movement. I firmly believe in revolutionary syndicalism as the way to transform society. The Charter of Amiens is a nice read on the subject.

    I'm a strong supporter of free software and free culture (“free” as in “freedom”), and of the open access movement in particular.

    I like pirate's culture a lot. Pirates crews were among the first anti-authoritarian, egalitarian, anti-statist, internationalist, and self-organized societies.

    I also value hip hop culture, as I love words, language, figures of speech, and constrained writing. I think that many of the best poets and language technicians call themselves MCs or deejays nowadays.

    I maintain a list of books on the miscellaneous page, and I believe this list captures me quite accurately.

    Shining sun for the smile
    Some music for the vibe
    Loads of love for my tribe
    A hammock for lifestyle


    The best way to contact me is by email at either “r at uzy.me” (personal) or “pr at up8.edu” (work). You can also send me paper emails using the following non RFC 3696 compliant address: “Pablo Rauzy, UFR STN / Dpt PIF, 2 rue de la Liberté, 93526 Saint-Denis Cedex, France”, if you are this kind of hipster. At this address I live in office A184 in the building A of the Paris 8 campus. Oh and by the way, I more or less look like this.
