Faculty and Research Interests

​Dr. Avery is an Associate Professor in the Department of Microbiology, Immunology and Pathology. Her laboratory studies immune responses to malaria and the pathogenesis of malaria-induced anemia. She also is interested in understanding prognostic factors in canine lymphoma and oversees a clinical diagnostic laboratory that provides flow cytometry and lymphoma molecular diagnostic service for veterinarians across the United States.

​Dr. Bradley is a Post-Doctoral Researcher in the Department of Clinical Sciences. She is investigating the pathogenesis of chronic liver disease in Standard Poodle dogs, as well as the use of novel immune suppressants for treatment of chronic liver disease in dogs. She is also helping to spearhead efforts to develop stem cell therapy as a new approach to the treatment of acute and chronic liver disease in dogs.

Dr. Dow is the Director of Center for Immune and Regenerative Medicine at CSU. He is a Professor in the Department of Clinical Sciences and in the Department of Microbiology, Immunology and Pathology. His laboratory studies immune responses, specifically as they relate to vaccines and immunotherapies. Members of his research group are investigating new vaccines for cancer and infectious diseases as well as immune mechanisms regulating stem cell therapy. The Dow lab is currently conducting clinical trials on the use of stem cell therapy for treatment of chronic kidney disease in cats and chronic hepatitis in dogs. His lab is also developing new vaccine approaches to treat and prevent cancer, as well as new immunotherapy approaches to treatment of chronic infections.

​Dr. Ehrhart is a Professor in the Animal Cancer Center in the Department of Clinical Sciences. Her laboratory investigates new approaches to improve bone healing for application to radiation therapy and bone cancer treatment. Current projects include the use of local or systemic administration of mesenchymal stem cells to stimulate healing of allogeneic bone grafts following bone cancer surgery.

​Dr. Gonzalez-Juarrero is an Associate Professor in the Department of Microbiology, Immunology and Pathology. Her laboratory studies immune responses in TB infection, using mouse and goat models of infection. She is currently investigating the use of siRNA inhibition of specific cytokines such as IL-10 as a novel immune therapeutic approach to treatment of chronic TB infection.

​Dr. Goodrich is an Associate Professor in the Department of Clinical Sciences. Her laboratory studies new approaches to bone and joint healing in equine atheletes, including gene therapy and stem cell therapy. Her laboratory currently is investigating the use of gene-modified mesenchymal stem cells to suppress joint inflammation in equine joint disease.

​Dr. Guth is a Research Scientist in the Animal Cancer Center and Department of Clinical Sciences. She currently is investigating immunotherapeutic approaches to cancer treatment. Among her projects is a studying investigating the use of cancer stem cell vaccines as a new approach to cancer immunotherapy.

​Dr. Kisiday is an Associate Professor in the Department of Clinical Sciences. His laboratory studies factors that regulate the maturation of mesenchymal stem cells into functional cartilage and bone tissues. His studies investigate the influence of substrates and specific growth factors on the mechanical properties of the regenerating mesenchymal stem cells.

​Dr. Lappin is a Professor in the Department of Clinical Sciences. His laboratory studies immune responses to vaccination against respiratory viruses in cats, as well as immune responses to feline vaccines. He also oversees a large diagnostic service for feline infectious agents, including Toxoplasma gondii, Bartonella, Ehrlichia and others.

​Dr. Orton is a Professor in the Department of Clinical Sciences and the Director of the Animal Heart Center. His group studies the pathogenesis of valvular heart disease in dogs and humans. His laboratory also uses new approaches to inhibit immune responses against xenogeneic heart valves.

​Dr. Quimby is a Clinical Instructor in the Department of Clinical Sciences. She studies the role of mesenchymal stem cell therapy for feline chronic kidney disease and the impact of therapy on intra-renal inflammation, as assessed by urinary cytokine responses.

​Dr. Ryan is an Assistant Professor in the Department of Environmental & Radiological Health Sciences. Her laboratory studies the role of phytonutrients in stimulating intestinal mucosal immunity and protection against infectious agents and cancer.

​Dr. Schenkel is an Associate Professor in the Department of Microbiology, Immunology and Pathology. His laboratory studies the immune pathogenesis of chronic interstitial lung disease and fibrosis, using a mouse model. He also investigates the signals that regulate recruitment of white blood cells into tissues during inflammatory responses.

​Dr. Twedt is a professor of small animal medicine in the Dept of Clinical Sciences. He is a pioneer in the study of liver diseases of dogs and cats and has developed several new approaches to managing chronic liver disease. Currently, he is involved in developing new stem cell therapy based approaches to treatment of chronic liver disease in dogs.

Craig Webb

Dr. Webb is an Associate Professor in the Department of Clinical Sciences. His particular interests are in gastroenterology (liver disease, inflammatory bowel disease), including the effects of diabetes mellitus on oxidative injury in cats and dogs. He is also investigating the effectiveness of mesenchymal stem cell therapy for treatment of inflammatory bowel disease in cats.

​Dr. Webb is a Research Scientist in the Department of Clinical Sciences. She investigates the use of mesenchymal stem cells for suppressing airway inflammation in mouse asthma models. In addition, she investigates the mechanisms by which mesenchymal stem cells suppress T-cell responses in mice and cats.

​Dr. Zabel is an Associate Professor in the Department of Microbiology, Immunology and Pathology. His laboratory investigates the immune pathogenesis of prion diseases, specifically chronic wasting disease, and how complement proteins and white blood cells facilitate the spread of the organism. In addition, his laboratory investigates novel immune therapeutic approaches to controlling prion infection in the brain, using mouse models of infection.
