Telomeres and genome stability

Research focus

Chromosome integrity and the proper partitioning of the genome to daughter cells are essential prerequisites for the stable inheritance of genetic information over multiple cell divisions. Our two main research interests are the molecular mechanisms that govern the stability of chromosome ends and the regulation of chromosome behavior during meiosis.
