machine learning scientist
I am the head of machine learning Research at Sonos, focusing on privacy-first speech recognition for voice experiences. I was previously the director of machine learning research at Snips (acquired by Sonos in November 2019) that I joined in February 2017.
Prior to joining Snips, I was a PhD student at the theoretical physics lab of the École Normale Supérieure (Paris). I focused on high-dimensional inference with graphical models in the context of protein structure prediction.

At Sonos (and previously Snips), we consider the problem of spoken language understanding on small devices typical of IoT applications. We work on designing embedded, private-by-design SLU systems with performance on par with cloud-based commercial solutions. I filed 3 patents currently under review. I have worked on several topics in automatic speech recognition: keyword spotting in the context of wake word detectors, natural language understanding, sentence generation, etc.

I pursued my PhD under the supervision of Rémi Monasson and Martin Weigt at the lab of theoretical physics of the École Normale Supérieure (Paris). I focused on maximum entropy graphical model inference and its application to genomic data, especially protein structure prediction. I discussed the extension of these approaches to other challenging fields, such as sequence folding prediction and homology detection. Through an extensive study on both artificial and biological data, I provided a better interpretation of the central inferred parameters, up to now poorly understood. I presented a new and more precise procedure for the inference of generative models, which lead to further improvements on real, finitely sampled data.

In January 2018, I took part in the DAT-ICU datathon for intensive care, aiming at presenting a clinical project using the MIMIC database (data about 50 000 intensive care unit patients). We proposed to associate a clinical print to each patient stay, allowing for instance to identify clusters of similar patients in a non supervised approach. We presented an algorithm of clinical data (textual and numerical) dimensionality reduction based on deep learning techniques.
My team won the first prize.

During my master 2, I worked at the "Physico-Chimie" lab of the Institut Curie under the supervision of Jean-François Joanny. I developed a theoretical model based on active gel theory and performed numerical simulations to study the effect of cell migration on morphogenesis in biological tissues.

I enjoy giving talks and discussing new ideas with people. I am very much interested in finding ways to present and apprehend complicated theories. I could not agree more with the great physicist Richard Feynman who said "If you cannot explain something in simple terms, you don't understand it".
On another topic, I am worried about the gender balance issue in machine learning, and I try to raise awareness on that specific subject.

- Designing small, fast, and accurate models to extract the intent and relevant informations from a phonetic representation of a spoken query given by an Acoustic Model and conducting research to improve the end-to-end, speech-to-meaning accuracy of these models.
- Designing small, fast, and accurate models to detect a predefined keyword in a continuous audio stream and conducting research to improve the accuracy and computational efficiency of these models.
- Leading the effort in publishing scientific papers (2 at ICASSP 2019, 1 at a workshop at ICML 2018, see Research section) and contributing to the community by open-sourcing code.
