Research interest

Since my third year of studies in Chile I was amazed by the environmental power of bacteria. Especially with the fact that such a small organisms are able to cope with tremendous persistent and hazardous contaminants. The fascination increased when I started to learn the complexity of bacterial metabolism during degradation of these compounds, and I have to say that until today degradation of contaminant by microorganims is a world of surprises for me. As a very general area of research I have used several molecular tools to try to understand the response of bacteria and its metabolism to different environmental conditions, which could constitute a stress or not. My current research, corresponding to my PhD thesis, is to study the effect of oxygen variations on catabolic gene expression of toluene degraders as they could occur in the rhizosphere (AXIOM). In parallel, I contribute to the research topic of anaerobic degradation of monochlorobenzene in groundwater (Dr. Ivonne Nijenhuis), where we try to detect microbial communities involved in the degradation of this chlorinated solvent. In the next starting project (BACSIN) we would like to investigate the effect of different abiotic stress conditions on bacterial catabolic pathway and its interactions with plant systems; and of course continue a never ending surprising story.
