Josiane Geffroy-Cillard, PhD

Josiane Cillard is Emeritus Professor at the University of Rennes 1, France. She has been Professor in Cellular and Molecular Biology at the Faculty of Pharmacy, Rennes. She was graduated  as Pharmacist and received her PhD in Pharmaceutical Sciences from Rennes University. 

She is Doctor Honoris Causa of the University of Buenos Aires. She was a member of the SFRR-Europe committee from 1996 to 2000 and will be the next President Elect of SFRR-Europe. She has been President of SFRR-France from 2003 to 2014. She was distinguished by the Oxygen Club of California as Life Time Honorary member and received the Science and Education Award. She organized five International Symposium on « Nutrition, Oxygen Biology & Medicine » in Paris. 

 Her research interests are focused on the modulation of cellular oxidative stress by antioxidants and exercice. She reported early (1976-1981) that α-tocopherol at high concentrations in micelles caused a prooxidant effect which was suppressed by vitamin C. In 1986 she showed that flavonoids are good scavengers of hydroxyl and peroxyl radicals and that they protect cells from iron toxicity by their ability to form complexes with intracellular free iron. These complexes are then released from the cells. She highlighted that myricetin was able to induce DNA-enzyme repair and to decrease oxidative DNA-base damage. Another research focus of Dr Cillard was to investigate the protective role of NO in iron and ethanol toxicity. Presently, Dr Cillard pursues her research on adaptation to oxidative stress by exercise in obesity and diabetes. 

In France she was awarded the Montgolfier Prize and the Chaptal Prize and she has been decorated by the French Republic as Chevalier de la Légion d’Honneur and Chevalier de l’Ordre National du Mérite.
