Since August 2008 I am professor in Systems Biology at the VU University Amsterdam. My Systems Bioinformatics group focusses on systems biology with a special focus on integrative bioinformatics. It aims at forming bridges between the classical bottom-up approaches in systems biology and the more data-driven approaches in classical bioinformatics. We combine experimental, modeling and theoretical approaches to study cellular physiology, with an emphasis on metabolic networks.
I am working on a kinetic model of the central metabolism as well as on a genome wide model of Streptococcus pyogenes.
Tools: gel-based and gel-free proteomics, 2-D Gel Electrophoresis, bacterial chemostat culture, Mutant and Strain Construction, qRT-PCR, molecular biological techniques (RNA/DNA techniques, Chromatography
Professor in biotechnology at the Dept. Chemistry, Biotechnology and Food Science. I am heading "Laboratory of microbial gene technology and food microbiology" that consists of approximately 20 members (staff members, technicians,and students). During the last 20 years my research has been focused on lactica acid bacteria with a focus on bacteriocins of lactic acid bacteria.These studies have included purification and chemical and genetic characterization of such peptides followed by biosynthesis
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
