About me (briefly):

I am a former research associate of the Belgian National Fund for Scientific Research (F.N.R.S.) and, since 1998, 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 probability and statistics, information theory and coding, stochastic processes, machine learning and data mining.

My research interests :

Back to top of this page Machine learning, in particular tree based models, graphical models, and reinforcement learning, with a focus on complex and large scale systems analysis, optimization 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 systems reliability management and optimal decision making under uncertainties (system operation, asset management, grid development)

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