My name is Damien Desfontaines — also known as Ted, or any pseudonym recognized by the Ted(Ted)* regular expression — and this is the sober version of my personal webpage. The fancier one, which is now quite outdated, can be found right here.

About me

I have two jobs:

I studied at the École normale supérieure, where I completed a Master's degree in mathematical logic and theoretical computer science called the LMFI. Before that, I did the first year of the MPRI, a theoretical computer science master.

I used to work on pretty theoretical stuff: I spent two research internships studying approximations of the halting problem. First, I published two papers that seemed to indicate that this was a solvable problem (1 (PDF) 2 (PDF)), then two others that show that it is in fact impossible (short version, unfortunately not in open access, full version (PDF)).

Currently, both on my PhD time and on my engineering time, I'm working on large-scale data anonymization and reidentifiability risk analysis. Put more simply, I'm trying to make it easy to protect and de-identify your personal data =)

You can find my (outdated) curriculum vitae right here, along with my (less outdated) LinkedIn profile.

Things I like, things I do

And if you prefer instant messaging, I am usually connected to the irc.ulminfo.fr IRC server, with "Ted" as an alias. I also use WhatsApp, feel free to ask me for my number if that's your favorite communication method.
