While at AIMS, Thierry focused on a simulation study of the apriori algorithm that is widely used in the mining of frequent patterns from transactions databases. His work involved the design of appropriate data structures such as arrays of linked lists used to implement the algorithm as computer software, and the running of simulations using market basket data to determine the performance characteristics of the algorithm on a relatively small computer equipped with 4 GB of RAM.

Thierry obtained his PhD in Applied Artificial intelligence from the University of Abomey-Calavi | IMSP (Benin) and is currently the vice dean of the institute of Applied Statistics at the University of Burundi.
