Pierrick Legrand received his PhD in applied mathematics (multifractal analysis, signal processing) from "Ecole centrale de Nantes" and from Nantes university in december 2004.

During his thesis, under the supervision of Jacques Levy-Vehel, he developed interpolation and denoising methods based on Hölderian regularity and wavelets. He also proved that these methods reach an optimal rate of convergence. During his thesis he was in charge of the development of FracLab, a free matlab toolbox. Website.

In 2005 he received a post-doctoral position shared between the Evovision group at CICESE research center (Ensenada, México) and INRIA COMPLEX Team (Rocquencourt, France). At that time, under the supervision of Gustavo Olague and Evelyne Lutton, his main research goals concerned the combination of genetic algorithms and multifractal analysis methods in order to solve applied image processing problems.

In 2006, a second post-doctoral position allowed Pierrick Legrand to develop the first genetic algorithm running on a pocket PC. The aim of this project was to provide new methods used to parameterize cochlear implants and to make the implant more adaptable to the environment. This work proved the efficiency of interactive evolution for this purpose.

On september 2006, he became associate professor at the university of Bordeaux2 (UFR sciences and Modelisation) and researcher at the IMB (Institut de Mathématiques de Bordeaux, UMR CNRS 5251), both of which are positions he currently holds. He was also researcher in the INRIA ALEA team and he is actually in the CQFD Inria team.
