Mathieu is an Associate Professor of Diagnostic Imaging at the School of Veterinary Medicine at the University of California, Davis, where he has been a faculty member since 2007. He earned his DVM degree from the National Veterinary School of Lyon in France in 2002 and a Master's degree from the University of Montreal in Canada in 2004.

After completing his radiology residency at the University of Pennsylvania, Mathieu became a diplomate of both the American College of Veterinary Radiology and the European College of Veterinary Diagnostic Imaging in 2007.

Mathieu's research focuses on musculoskeletal imaging in horses, with over 50 publications in peer-reviewed journals. He has been a pioneer in the use of positron emission tomography (PET) in horses, contributing to the development of both research and clinical applications.

Sarah Puchalski is a native of Roberts Creek, British Columbia, Canada, and grew up riding horses in the BC countryside, competing actively in 3-day eventing.  She obtained a B.S. in Biology from Simon Fraser University in Burnaby, BC and went to veterinary school in Saskatoon, Saskatchewan, where she graduated with distinction in 1999.  From Saskatoon, she moved to Pennsylvania as an intern/resident in field service sports medicine at the University of Pennsylvania’s New Bolton Center from 1999-2001.  From New Bolton Center, Dr. Puchalski entered a four-year residency in diagnostic imaging at the University of California, Davis.  She obtained board certification in the American College of Veterinary Radiology in 2004, passing the grueling examination on her first attempt. 

In 2005, Dr. Puchalski joined the faculty in diagnostic imaging in the Department of Surgical and Radiological Sciences, UC Davis School of Veterinary Medicine, as an Assistant Professor.  During this time, she divided her focus between didactic and clinical teaching, research, service to the school and clinical radiology.  In the classroom, she led the general large animal radiology course and was a co-instructor in the equine lameness and radiology course.  Her research interests predominantly surround the use of novel imaging techniques for the diagnosis of lameness conditions in equine athletes.   As she has gained experience in this field, she has developed an international reputation for her expertise.  Dr. Puchalski was awarded tenure at the University in 2012 and promoted to Associate Professor, and has authored scientific, educational and lay articles as well as contributed to numerous textbooks. 

Dr. Puchalski left the University in late 2013 to open her own practice as a diagnostic imaging consultant.  In the winter months she is based in Wellington, Florida at Palm Beach Equine Clinic and during the remainder of the year in Petaluma, California at Circle Oak Equine.  As a show jumper, competing actively in Wellington, Florida at the Winter Equestrian Festival and in Northern California, she understands the challenges of equine ownership and what may be needed to keep these athletes sound.

Vanessa graduated in 2011 from the University of Bern and subsequently undertook internships at Rossdales and at a large equine hospital in Florida, USA before returning to Rossdales as an orthopaedic assistant in 2013. She has a keen interest in all diagnostic imaging modalities and is passionate about their use in the diagnosis of musculoskeletal disorders in particular.

Vanessa successfully completed a residency in Veterinary Diagnostic Imaging with the European College (ECVDI) under the guidance of veterinary specialists at Rossdales Equine Diagnostic Centre and Dick White Specialist Referrals. She became a Diplomate of ECVDI in February 2020 and was awarded RCVS recognised specialist status in March 2020.
