About

I am a Chargée de Recherches (equivalent to a tenured facutly position) at CNRS since October 2017. I am currently hosted in the Inria CEDAR team at Laboratoire d'Informatique de l'École Polytechnique. Before September 2022, I was hoste in the Laboratoire d'Informatique de Grenoble. Prior to this I was a postdoc at the Max Planck Institute for Software Systems working with Krishna Gummadi. I obtained my Ph.D. in 2014 from the Pierre et Marie Curie University in Paris under the supervision of Renata Teixeira.

To audit and study risks with online platforms, we need data! If you want to help our research, please consider donating data about the content you see online by installing CheckMyNews (version Française).


My research is supported by an ERC Starting Grant (2022-2027).

I am looking for motivated interns, Ph.D. students, and postdocs. If you are interested in working in security and privacy problems related to social computing and online advertising, drop me an email with a brief statement of interest and a CV.

Research Interests

I work on problems related to AI and Society. As a security and privacy researcher, I spend a lot of time thinking about how social media systems and online advertising can be used to negatively impact humans and society and what can we do against it.

In practice, we design measurement methodologies and experiments to understand problems in AI-based systems. We collect and work with data from real systems and real humans.

This topic is interdisciplinary by nature. We work with economists and cognitive scientists to better understand humans and work with legal scholars to find appropriate protective solutions.

For a quick glimpse over some of my latest research, here are a few articles I co-authored, and that explain our work for a general audience:

Personal

(sometime before 2016) Patrick Loiseau is my wonderful husband. It is rather cool be able to work together and do science over a glass of wine.
Update 1 (sometime in 2017): ... after our son goes to bed .
Update 2 (sometime in 2018-2019): This statement is no longer true after the birth of our second son... we are just walking zombies, amazed another day passed, and we are still alive!
Update 3 (april 2020): Life continues to be crazy with these guys.
Update 4 (dec 2022): There is light at the other end of the tunnel! :) Life with a 4-year-old and a 6-year-old is surprisingly easy (most of the time)! And here is a photo to prove it.:)
