Welcome To My Homepage
Since September 2025, I have been teaching in the Department of Engineering at the University of Limoges.
I defended my thesis in July 2024 at the Institute of Mathematics of Bordeaux (IMB) under the supervision of Karim Kellay and Philippe Jaming.
Manuscript available at: https://hal.science/tel-04646599v1.
My research is centered around harmonic and non-harmonic trigonometric polynomials.
Keywords: Littlewood conjecture, Ingham’s type inequalities, non-harmonic Fourier series.
