I am a motivated mathematics researcher with a demonstrated history of working in the higher education sector. I am skilled in mathematics and programming, with a strong academic background that includes a B.S. in Mathematics and an M.S. in Applied and Computational Mathematics from the Lebanese American University, as well as a Ph.D. in Mathematics from Université Claude Bernard Lyon 1.

Currently, I am a researcher in mathematical modeling and scientific computing at the Institute for Mathematical Research of Rennes (IRMAR), and a lecturer at the University of Rennes 1, where I teach various undergraduate and graduate mathematics courses.
