The main interests of the group are a) to analyze gene expression and regulation from high throughput sequencing datasets and b) to assemble, annotate and compare newly sequenced genomes whith a special focus on insects and human pathogenes. Other interests include the development of databases and bioinformatics tools using ontologies and other sematics approaches to promote interoperability between different but related datasets.
