Intérêts de recherche

Our research interest focusses on the molecular events surrounding the chromatin remodeling in spermatids. The process involves the formation of transient DNA strand breaks. As this could represent an important source of genetic instability, will are investigating their distribution and the mechanisms by which they are created and repaired.
