About me (briefly):

I am a former research associate of the Belgian National Fund for Scientific Research (F.N.R.S.) and presently professor of stochastic methods in the
Department of Electrical Engineering and Computer Science, at the University of Liège.

I do research in machine learning, stochastic simulation, and optimization, with applications in electric power systems, industrial process control, bioinformatics and computational systems biology. I am teaching courses on information theory and coding, stochastic processes, machine learning and data mining.

Since a few years, I have been strongly involved in the bioinformatics and systems biology research of the GIGA-R centre of the University of Liège (Systems Biology and Chemical Biology @ GIGA-R, Bioinformatics and Modeling @ GIGA-R, Alma-in-Silico project @ GIGA-R).

My research interests :

Back to top of this page Automatic learning, in particular tree based models, graphical models, reinforcement learning, with a focus on complex and large scale systems analysis and control,

Bioinformatics and computational systems biology, in particular biological systems and structures modeling, exploitation of proteomics, genomics, clinical and biomedical imaging data

Electric power transmission, generation and distribution systems, security and risk assessment, sequential decision making, optimization and long-term planning

Development of methods and applications of automatic learning, in particular in data mining, image and time-series classification, as well as for optimization
