## Welcome!

I am a Lecturer-Researcher in Mathematics since June 22,2020. At the Mathematics Department of the Higher Teacher Training College of the University of Yaoundé I (Cameroon). I work on general algebra, more particulary on algebraic hyperstrucutres , algebras from multivaluated logics, fuzzy sets and algebraic coding.

Since March 2020, I have been doing a PostDoc at the SCHOOL OF THREE GORGES ARTIFICIAL INTELLIGENCE, Chongqing Three Gorges University (China).

Within the Research Team in Algebra and Logic (ERAL) of the University of Yaounde I, I am an assistant in chaege of the organization.

## My skills

**E-LEARNING RESOURCE DEVELOPER**

By development software such as the OPALE editorial chain, we design resources for E-learning that we distribute on platforms such as Moodle.

**PROGRAMMING**

Our research has often led us to use the following software:

Maple

Sage

Gap

Pari/Gp

**MATHEMATICS TEACHING**

Algebra

Geometry (Bachelor)

Data Analysis (SPSS, R)

## Research teams
