Current position

Associate professor at Ecole Centrale de Nantes

Supervisor of the specialization "Product design and Industrial Systems developments"

Research activities

Main theme: Improve product design by taking into account the subjective response of customers

Issues: - How to capture the subjectivity of human assessment ?

How to integrate the subjective response into the design process ?

How to transform the subjective response into requirements ?

How to prescribe useful requirements for the engineer ?

How to manage simultaneously subjective and objective requirements ?

How to use the "optimal design" concept with the subjective response ?

To do this, we have to determine which existing methods and new propositions can be used to accomplish the following steps:

Understand and express need

Specify in a relevant manner requirements of a new product

Assess performance of new solutions

Find "optimal" solutions

Characterization of this research area:

It’s an important challenge for the optimization of products,

It needs a multidisciplinary approach : engineering, industrial design, psychometry, sensorial analysis, sensorial metrology, marketing.

It’s a way to establish a link between various research areas: engineering sciences, marketing or human sciences,

It’s an attempt to put together convergent (scientific) and divergent (creative) thinking.

Tools and methods used:

Multidimensional scaling

Semantic differential method

Preference mapping

Factorial analysis

Property fitting.

Theme n°1: Musical Acoustics

Collaboration with the Laboratoire d'Acoustique de l'Universite du Maine (LAUM) UMR CNRS 6613, team "ondes guidées, auto-oscillations" : Joël GILBERT

In order to understand the behaviour of playing brass instruments, we have developed an "artificial mouth" that permits to make objective tests on instruments (trumpet or trombone), overlooking the natural adaptation faculty of the musician. Moreover, the artificial mouth is a useful set-up to improve physical modelling and could assist the manufacture of musical instruments. The System is operational. The device has belongs to the top hundred facts of the CNRS for 1998.
