Specialised lectures to residents in oncology, breast surgery and radiotherapy since 1998 in several Specialised Schools and Institutes such as the Centre René Huguenin, the Institut Curie, the European School of Oncology (ESO) and European School of Surgey (EEC), including live surgery.


I was first trained and graduated as a gynaecologist surgeon. In 1996, I was recruited at the Institut Curie and I progressively focussed my activities on breast cancer surgery, acquiring specialist skills in reconstructive breast surgery, which became an important part of my professional activity. After a few years, I concentrated on sentinel node biopsy and issued numerous related publications. At the moment, I am in the process of experimenting a new technique named Axillary Reverse Mapping for which I am the principal investigator through a National Multicentric Study “Sentibras” .
In close association with Dr K. B. Clough (Chief of the Department of Breast and General Surgery in Institut Curie from 1996 to 2004), I have also focused my research on the extension of the surgical techniques for breast cancer patients and have contributed to the development of an « oncoplastic » approach for tumors that would not be suitable for standard conservative surgery. These oncoplastic procedures extend the scope of breast surgery, traditionally limited to wide local excision or mastectomy.
In 2005 I left the Institut Curie to assist Dr K. Clough in the establishment of the Paris Breast Centre, France’s first Breast Center. The Paris Breast Center treats more than 500 new breast cancer cases per year and is one of the leading private institutions in France for treatment and education. In parallel, I remained in the Public Health Sector at the Hospital Europeen George Pompidou ( Service of the Prof F LECURU) with a view, inter alia, to pursue my research work, in particular the above mentioned “Sentibras” Protocol.
