Martijn Bekker (1979) was born in Amstelveen (The Netherlands). He started his studies in biology in 1997 at the University of Amsterdam, and graduated in 2003 with specializations in molecular microbiology and in immunology. The internships during his undergraduate studies were carried out in the labs of Prof. dr. B. Oudega (VU, Amsterdam, The Netherlands) and Prof. dr. F. Heffron (OHSU, Portland, Oregon, USA). He continued with his graduate studies in 2003 in the Laboratory for Molecular Microbial ...
SysMO is a European transnational funding and research initiative on "Systems Biology of Microorganisms".
The goal pursued by SysMO was to record and describe the dynamic molecular processes going on in unicellular microorganisms in a comprehensive way and to present these processes in the form of computerized mathematical models.
Systems biology will raise biomedical and biotechnological research to a new quality level and contribute markedly to progress in understanding. Pooling European research ...

Challenge: Comparative analyses, as demonstrated by comparative genomics and bioinformatics, are extremely powerful for (i) transfer of information from (experimentally) well-studied organisms to the other organisms, and (ii) when coupled to functional and phenotypic information, insight in the relative importance of components to the observed differences and simalities. The central principle of this proposal is that important aspects of the functional differences between organisms derive not ...
