About Me

I'm Mohamed Maouche a Research Scientist (permanent position - ISFP) at Inria (Privatics Team). Previously, I was working in the DSVD Chaire in partnership with Renault Group. I also worked on private machine learning for speech processing at Inria in the Magnet Team (MAchine learninG in information NETworks). Before that I receivied my PhD in computer science from INSA-Lyon France in 2019 (working on location privacy).

My main interest is to build machine learning systems that manages a good trade-off between privacy and utility. I explore anonymization techniques and re-identification threats on different data types and applications.
