Bio

Gaël Varoquaux is a research director working on data science at Inria (French computer science national research) where he leads the Soda team. He is also co-founder and scientific advisor of Probabl.
Varoquaux's research covers fundamentals of artificial intelligence, statistical learning, natural language processing, causal inference, as well as applications to health, with a current focus on public health and epidemiology. He also creates technology: he co-founded scikit-learn, one of the reference machine-learning toolboxes, and helped build various central tools for data analysis in Python.
Varoquaux has worked at UC Berkeley, McGill, and university of Florence. He did a PhD in quantum physics supervised by Alain Aspect and is a graduate from Ecole Normale Superieure, Paris.

Contact

email

firstname.lastname@inria.fr

I get a lot of email, and fail to answer all of it. My apologies.

Seeking advice: Do not write to me to ask me about some software, even if I am the maintainer. Write to the relevant mailing list or open a ticket. If you ask me advice on data processing, please be aware that I might not reply, or I might post my reply on a public mailing list or social network, in an attempt to have more people benefit from it.

Job seeking: If you are looking for an internship, write me a concise email, telling me why you are interested in working with me, and with a CV (even if it is only for a preliminary enquiry). Also, check our group's job offer page. I am more likely to reply to people from under-represented groups, because diversity is important to me.

Invitations: I enjoy giving talks and am flattered by invitations. But I am trying to fly no more than once a year, to reduce my carbon footprint. I more likely to give remote talks, or consider traveling if not too far by train from Paris.
