-  * Background: I arrived at Polytechnique Montreal in September 2016 for a double degree with [[https://www.utc.fr|Université de Technologie de Compiègne]] in France. I began in January 2017 a research Master's in mechanical engineering in the [[http://lava.polymtl.ca/|LAVA]] turbomachinery lab. I was really interested by the black box optimization course I attended and I wanted to combine both mathematical and mechanical aspects in a Ph.D. project. I had the opportunity to follow a Master’s-to-Ph.D. fast track program and I began my Ph.D in January 2018.

-  *  Project: My works focuses on the **development of a methodology for the design of aircraft engine blades, which involves time-consuming simulations and discontinuous functions**. As a consequence, I develop a **new MADS algorithm revealing and escaping discontinuous areas of the space of variables**.
