Our scientific interests concentrate on cancer genetics and the genetics of the senses. We use various techniques in our routine practice, from molecular biology and cytogenetics (microarrays, NGS, pyrosequencing, FISH and FICTION) supplemented by functional analyses. The aim of the research is the identification of genomic and epigenomic alterations that contribute to the development of neoplasms and diseases of the sensory organs. To that end, we work closely with renowned Polish and foreign scientific groups.
