Catherine grew up in France and obtained her doctoral veterinary degree from the School of Veterinary Medicine in Lyon. After working in private practice in France for several years, she completed a residency program in Equine Reproduction at UC Davis, California. Catherine then joined on and off the Theriogenology department team at UC Davis as a clinician. She is now the Chief of Service. 

She has a special research interest in ultrasonography of the pregnant mare. During her residency, she began studying the ultrasonographic appearance of the placenta and created an index called CTUP (for combined thickness of the uterus and placenta), which is now used in routine to diagnose placentitis. She later focused on the fetus, establishing growth charts, studying parameters of the biophysical profile, and demonstrating that fetal sexing could be performed during mid-gestation. Her latest research involves in utero assessment of fetal bone development.
