Education and Training

I received the degree of Industrial Engineer in Biotechnology from the Institut Supérieur Industriel de la Province de Liège, Belgium, and my B.S. and Ph.D. in Applied Natural Sciences from the Université Catholique de Louvain, Belgium. I was a postdoctoral fellow and a faculty member at the Institute for Genomic Research (TIGR) / J. Craig Venter Institute (JCVI) in Rockville, MD from 1997 to 2007. I am currently a tenured Professor at the  Institute for Genome Sciences (IGS).

Biosketch

I have been in the genomics field for over 30 years, developing an extensive expertise in microbial genomics, functional genomics, comparative genomics, and bioinformatics. I have led the genome sequencing and analysis of many organisms, starting with eukaryotic chromosomes then shifting towards bacterial pathogens. I was the lead author on the first published genomes of  Neisseria meningitidis,  Streptococcus pneumoniae, and  Streptococcus agalactiae. In collaboration with the group of Dr. Rino Rappuoli (former GlaxoSmithKline Vaccines, Novartis Vaccines and Diagnostics, and Chiron Vaccines), I pioneered the fields of reverse vaccinology and pangenomics. The former makes use of genomics and bioinformatics to identify novel protein candidates for vaccine development. The latter is the characterization of the genome content of an entire species, showing that it often far exceeds the genome content of any individual isolate

I have supervised the development of bioinformatics tools to study bacterial genomes and transcriptomes, and conducted many studies of bacterial diversity, transcriptional profiling, and functional genomics analyses to identify host and bacterial genes involved in host-pathogen interactions, virulence, and adaptation.

Research/Clinical Keywords

Bacterial pathogens, comparative genomics, functional genomics, RNA-seq, Tn-seq, bioinformatics.
