A picture of me, smiling, looking to the right.


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 The fancier one, which is now quite outdated, can be found here.

About me

I'm a staff scientist at Tumult Labs, a startup focusing on differential privacy. Before that, I was leading the anonymization consulting team at Google. My job is to make it easy to safely anonymize data.

In December 2020, I defended my PhD thesis at ETH Zürich, which I worked on part-time in the Information Security Group, under the supervision of David Basin.

Previously, 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.

You can find more information on my LinkedIn profile. I'm also @TedOnPrivacy on Twitter, and on Mastodon.


When I was studying for my Master's degree, I did research in theoretical computer science, and more specifically computability theory.

Since then, I've been working on data anonymization, and more specifically differential privacy.

I also serve as a program committee member for PETS (since 2020), PEPR (since 2022), and PPAI (since 2023). If you'd like to invite me to volunteer for another scientific conference or journal, please consult this blog post first.

Other publications, talks, interviews, etc.


To get in touch with me, you can send an e-mail to se.niatnofsed@neimad (beware when copying it). I also use WhatsApp and Signal, feel free to ask me for my number if that's your favorite communication method.

I also love to send and receive postcards. If that's also your thing, don't hesitate to ask me for my mailing address ♥
