Claire is a Research Scientist at DeepMind in London UK. She received her PhD from Telecom ParisTech in October 2017, under the guidance of Prof. Olivier Cappé. From January 2018-October 2018, she worked part-time as an Applied Scientist at Amazon in Berlin, while doing a post-doc with Alexandra Carpentier at the University of Magdeburg in Germany.
Her research is on sequential decision making. It mostly spans bandit problems, but Claire's interest also extends to Reinforcement Learning and Learning Theory. While keeping in mind concrete problems -- often inspired by interactions with product teams -- she focuses on theoretical approaches, aiming for provably optimal algorithms.
I will be leaving Deepmind in December 2022 and joining the University of Tuebingen, Germany as a Group Leader in January 2022. My group is supported by an Emmy Noether award for the project "Foundations for Lifelong Reinforcement Learning" within the AI Initiative.
I am hiring PhD students within the IMPRS-IS program, the deadline is on November 1st 2022. Please reach out if you have questions.
I will be attending NeurIPS 2022 in New Orleans, please reach out if you would like to meet :)

Service and Community
I am a reviewer or senior PC for all major conferences: NeurIPS, ICML, AISTATS, COLT, ALT, ICLR. I have been an Area Chair for ICLR 2021 and NeurIPS 2021. I am a Program Chair for the ICLR Blogpost track.
I strongly support community groups, in particular towards better diversity in our extended field (Computer Science and Stats). I have volunteered and area chaired for the WiML workshop many times and I am co-leading with Ruth Urner the WiML-T effort for Women in Learning Theory .
