Research

My research activities are centered on the monitoring of engineered systems.
It is a multidisciplinary field, from sensor design to decision-making.
I'm particularly interested in contributing to

Structural Health Monitoring with acoustic emission (details),
Formalisms for uncertainty representation, quantification and propagation (details),
Prognostics and Health Management (details),
Image and video analysis (details).

My research topics are

Deep learning for Structural Health Monitoring,
Acoustic emission streaming interpretation by unevenly spaced in time events clustering,
Cost-sensitive early classification of time-series using deep reinforcement learning,
Remaining useful prediction with low amount of data using belief functions.

In the past, i also worked on computer vision and image understanding.

My results are available on scholar and on scopus (publications), as well on github (some source codes).

I'm a member of the department of applied mechanics of FEMTO-ST institute.

HDR

My Habilitation à Diriger des Recherches (HDR, written in French) presents my contributions from 2008 to 2016 on the monitoring of engineered systems.

PhD thesis

My PhD thesis (written in French) between 2004-2007 at GIPSA-lab (Genoble), was about recognizing human motions in videos with moving camera. I had a strong connection with Costas Panagiotakis during this period who helped me a lot on human tracking for better feature extraction.

Master thesis

My Master thesis (written in French), earned in 2004 at LISTIC lab (Annecy), was about 3D tomographic image analysis of composite materials.
