Renée de Cremoux obtained her veterinary degree in 1991 (University of Toulouse) and a postgraduate degree in biology and agronomy (University of Rennes, France) in 1994. She joined the Dairy Products and Animal Health department of the French National Livestock Institute (Idele) as a project manager in 1993. She leads a Joint Technological Unit on ruminant health and welfare in partnership with the National Veterinary School of Toulouse, INRAE ​​(National Research Institute for Agriculture, Food and Environment), and ANSES (French Agency for Food, Environmental and Occupational Health & Safety; PBER Unit of the Ploufragan-Plouzané-Niort Laboratory). This collaborative initiative aims to design, evaluate, and promote the adoption of integrated ruminant health and welfare management measures to address the various dimensions and evolving constraints of livestock farming systems. Since 2012, she has contributed to the French animal health surveillance platform, and in particular to the development of an observatory for ruminant abortion diseases (since 2017). Within her animal health activities, she conducts applied studies requiring multidisciplinary approaches and investigates abortive diseases in small ruminants, milk quality, and udder infections. More recently, she has contributed to defining welfare indicators for small ruminants to be integrated into operational assessment tools. She is currently working on biosecurity approaches applied at territorial scales, as well as vector-borne diseases.
