Welcome To My Homepage

Since September 2024, I have held a temporary teaching and research assistant (ATER) position at the University of Bordeaux.

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.
