Keith Baar
Keith Baar, PhD
Dr Baar's research is focused on determining the molecular mechanisms underlying the physiological and functional adaptations of muscle to exercise. To delve deeper into the molecular mechanisms underlying the effects of exercise, Keith's lab is currently engineering muscle tissue outside the body with a particular interest in applying this model towards understanding muscle physiology and function. His recent work has used this model to show that the physiologic differences between fast and slow muscles can be retained in muscles engineered in vitro and has also used machines to alter muscle phenotype using different patterns of electrical stimulation. He is now using these techniques to study the effect of genetic manipulation on muscle function in an attempt to identify genes that could be targeted to improve performance or treat obesity, diabetes, and frailty.

Chris Murphy
Chris Murphy, DVM, PhD
Dr. Murphy has appointments as a professor of comparative ophthalmology in the School of Medicine's Department of Ophthalmology and Vision Sciences, and in the School of Veterinary Medicine's Department of Surgical and Radiological Sciences. Dr. Murphy is investigating: 1) modulation of cell behaviors by biophysical cues, with relevance to the design of improved cell culture ware, surgical implants and understanding disease processes; 2) development of improved organ preservation media, by which to markedly extend the length of time an intact organ can be stored; 3) engineering-inspired approaches to "engineer" a wound bed to promote healing; 4) optical performance in animals that evolved in response to challenging environmental conditions

Sean Owens
Sean Owens, DVM, Diplomate ACVP, Assistant Professor
Following an internship in small animal medicine and surgery, he completed a fellowship in small animal transfusion medicine at the University of Pennslyvania's Penn Animal Blood Bank. Dr. Owens completed his residency training in clinical pathology at UC Davis in 2004, and worked as a clinical pathologist with IDEXX Reference Laboratories, Inc., for two years prior to coming back to UC Davis. His research interests include red cell compatibility issues, blood banking, and transfusion medicine.

Sarah Puchalski
Sarah Puchalski, DVM, Diplomate ACVR
Dr. Puchalski attended veterinary school at the University of Saskatchewan and completed her residency training at the University of California, Davis. She is currently an assistant professor of diagnostic imaging, and her interests include cross-sectional imaging of the equine distal limb, and imaging of musculoskeletal disease. Dr. Puchalski has clinical expertise in cross-sectional imaging (CT and MRI) with an emphasis on equine lameness diagnosis. Research focus on the implementation of novel cross-sectional imaging techniques in equine orthopedics.

Susan Stover
Susan Stover, DVM, PhD, Diplomate ACVS
Dr. Stover focuses her research on the prevention of musculoskeletal injuries in equine athletes. Key contributions to the safety and welfare of the horse include development of joint fluid sampling techniques, discovery and characterization of lesions that predispose racehorses to catastrophic injuries, and elucidation of risk factors for injuries in racehorses. Current efforts emphasize the understanding of how training and injury affect fracture mechanics and fracture propagation in bones, as well as the effects of race surface materials and shoes on hoof and fetlock biomechanics and thus propensity for injury. She received the 2007 Pfizer Animal Health Award for Research Excellence, which recognizes research innovation and productivity of national significance. Her work has led to new recommendations for training methods, horseshoe types and, most recently, racetrack surfaces. Stover earned her veterinary degree from Washington State University and completed an equine surgery internship and residency at UC Davis, where she teaches veterinary students, residents and graduate students about equine musculoskeletal biomechanics, anatomy, and pathology.

Clare Yellowley
Clare Yellowley, PhD
Dr. Yellowley is an Associate Professor in the Department of Anatomy, Physiology and Cell Biology at UC Davis School of Veterinary Medicine. Recently, she has begun to study Mesenchymal stem cells, which are believed to represent a store of potential progenitors for tissue repair and regeneration. The focus of her research is to understand the role of stem cell recruitment and differentiation in bone development, maintenance and repair, including fracture repair. Dr. Yellowley is investigating whether the hypoxic environment at a fracture site stimulates the release of chemotactic factors from bone cells and subsequent migration of MSCs to that site to aid fracture repair. In addition, she is interested in the effects of decreased oxygen on the subsequent differentiation of stem cells down the osteogenic lineage.
