While at AIMS, Hervé studied the functioning principle and the convergence of the Gauss-Seidel method. Furthermore, using the fork-join paradigm of the programming language Java, he implemented an efficient version for sparse matrices following the idea of Yueqiang Shang developed in his publication entitled A distributed memory parallel Gauss–Seidel algorithm for linear algebraic systems.

Hervé is currently a DevOps Engineer at Connect Technology, Yaounde, Cameroon.
