Khalid Souilah

Khalid Souilah began his academic career at the Faculty of sciences of Oujda, Mohammed First University Morocco, where he had his master's degree in 2013, and he defended his PhD thesis in mathematics in 2016. In 2018, he joined the mathematics department of the Faculty of science of Oujda as an assistant professor of the higher education.

Souilah's research thematic system is divided between the bounded operators theory on Banach spaces, and the spectral theory in the Banach algebras. His research contributions are focused on the following subjects:

- Linear preservers problem: it consists of characterizing all linear, or additive, transformations on algebras that leave invariant certain subsets, functions, or relations.

- Perturbation classes problem: The aim is to completely determine the perturbations class, or the commuting perturbations class, of certain subsets of bounded operators or of certain parts of spectrum.
