I am a Senior Machine Learning Researcher at Secondmind.ai (ex Prowler.io) since February 2018. Beginning in November 2020, I will join Arno Solin’s group at Aalto University as a postdoctoral researcher on a part-time basis. My research interests lie broadly within probabilistic machine learning and reinforcement learning.

I completed a PhD under the supervision of Maneesh Sahani at the Gatsby Computational neuroscience Unit, UK. In my thesis work, I focused on auditory perception and explored how Bayesian theories of perception could account for various perceptual phenomena revealed in controlled psychophysical experiments. I also developped non-parametric methods for statistical data analysis. My undergraduate studies were in electrical engineering (Ecole Centrale de Nantes, France) and cognitive science (Ecole Normale Superieure, France).

Projects and other activities

I participated in the development of the scientific application Daydreaming, with financial help from the city of Paris through Science en poche. I started a scientific blog that I plan to revive soon. With the Gatsby Unit we participated in a Kaggle hosted seizure detection challenge and ranked 9/200 and we presented our work at a seizure focused conference. I’ve been involved in consultancy work with the company Swhere applying machine learning techniques to solve business problems.
