The combinatorial pattern-matching group develops combinatorial algorithms for pattern search and synthesis problems for sequential and higher-dimensional data. The group is interested in the basic research of the theoretical aspects of the area as well as in various applications, mostly in bioinformatics and information retrieval.
Recently we have focused in developing algorithms for assembling genomes from short read data. We have proposed new algorithms for correcting sequencing errors in the data. We have also developed new methods for the scaffolding phase where contiguous sequences assembled from the short read data are arranged into a linear order.
Another recent research focus is regulatory regions in genomes. We have developed new models based high throughput data for describing regulatory elements and we have proposed new algorithms for recognizing such elements in genomic sequences.
