Research interests 

My research interests focus on theoretical, experimental and numerical contributions in the field of mechanical systems and structural dynamics. 

My contributions include work based on highly efficient experimental and computational methods for physics and engineering, aiming to improve the understanding of the dynamic behavior of mechanical systems in various technology fields including automotive systems and aero-engines.

My research topics fall into the following broad categories:

Noise and friction-induced vibration :



Structural health monitoring:



Rotordynamics :



Applications :

Experimental bench FIVE@ECL

Since 2015, design of a new experimental test bench, called Friction-Induced Vibration and noisE at Ecole Centrale Lyon (FIVE@ECL),  has been developped by the research group  "Nonlinear Dynamics, Uncertainties, Mechanical Systems with Interfaces".

Financial supports from Institut Universitaire de France (IUF) and Institut Carnot Ingénierie@Lyon.

To be noted for the scientific community in the field of friction-induced noise and vibration : free experimental databases are available.

Research group "Nonlinear Dynamics, Uncertainties, Mechanical Systems with Interfaces"

Overview

The research group "Nonlinear Dynamics, Uncertainties, Mechanical Systems with Interfaces" (Laboratory of Tribology and Dynamics of Systems UMR CNRS 5513) is focused broadly on mechanical science and technology in order to conduct specific research and investigations into vibration problems for industry as well as the public sector. Research interests focus on theoretical, experimental as well as numerical contributions.

We are committed to realizing our research program through studies currently focused on five major areas:


People - permanent researchers and faculty members

 The research group   "Nonlinear Dynamics, Uncertainties, Mechanical Systems with Interfaces" includes a number of permanent researchers and faculty members and often involves PhD-students and post-doctoral researchers.
