Farewell to five retiring faculty

June 13, 2013

The School of Veterinary Medicine community offers farewell and thanks to five faculty members who retire this year. These individuals have embodied excellence in teaching, dedication to academic veterinary medicine and scholarly research accomplishments that are hallmarks of the school.

Bradd Barr

Bradd BarrDr. Bradd Barr earned his D.V.M. from Washington State University in 1975 and spent four years in veterinary practice before coming to UC Davis for a Ph.D. in pathology, which he received in 1983. He joined the faculty in 1985 as one of two pathologists at what is now known as the California Animal Health and Food Safety Laboratory System (CAHFS). 

Barr’s diagnostic acumen and thoroughness are a testament to the many original findings he contributed to the clinical research and diagnostic communities. In particular, his clinical research-related studies in protozoal diseases of the horse, bovine, marine mammals, and birds have been widely used as references; and his interdisciplinary research collaborations with a number of investigators inside and outside of UC Davis resulted in published manuscripts that provided new information for diagnosticians, protozoologists and practicing veterinarians. His discovery of new apicocomplexan protozoa, particularly in the genera Neospora and Sarcocystis, earned him international recognition. 

During his 28 years of service at CAHFS, Barr spearheaded the investigation of several disease outbreaks, developed and employed diagnostics for prion diseases, and enhanced the electromicroscopy and histology diagnostic capabilities of the lab. Barr was responsible for providing outstanding service to livestock and poultry producers, commodity groups in California and to the California Department of Food and Agriculture regulatory veterinarians. He helped respond to a devastating outbreak of avian exotic Newcastle Disease in California and bovine tuberculosis in the Central Valley. He also participated in extensive planning and surveillance exercises for bovine spongiform encephalothapy (BSE), West Nile virus and avian influenza, in preparation for containing any outbreaks that may occur in the state.

Barr provided instruction in comparative avian anatomy and clinical instruction in diagnostic pathology to residents and professional students. His weekly contributions to surgical pathology rounds were highly appreciated as he shared case studies that added to the experiential training of residents and department graduate students. He also served for more than a decade as an editorial advisor for the Journal of Comparative Pathology and continues to be active in providing continuing education regionally and nationally. 


Stephen Barthold

Stephen Barthold

Dr. Stephen Barthold earned his D.V.M. from UC Davis School of Veterinary Medicine in 1969 and his M.S. and Ph.D. in comparative pathology from the University of Wisconsin in 1973 and 1974. He is also a diplomat of the American College of Veterinary Pathologists. He returned to UC Davis in 1997 to direct the campus's new Center for Comparative Medicine, a joint venture between the School of Veterinary Medicine and the School of Medicine that investigates diseases afflicting both humans and animals. That same year, he was appointed to direct the UC Davis Mouse Biology Program, a campus wide program formed to invigorate and coordinate biomedical research that relies on the mouse as a research model.

As a veterinary pathologist, Barthold studies the interaction between infectious-disease agents and their hosts. While on the faculty of Yale University from 1974 to 1997, he played a major role in coordinating a team of researchers that investigated Lyme disease and developed a human vaccine for it. The vaccine was approved in 1998 by the Federal Drug Administration for use in humans. 

Barthold also is an internationally recognized authority on the diseases and biology of the laboratory mouse, the species in which he specializes as a veterinarian. He played a key role in nurturing a collaborative relationship between UC Davis and The Jackson Laboratory of Bar Harbor, Maine—the world's leading private research institution focusing on mouse-based biomedical research. 

In addition to Lyme disease, Barthold studied the mechanisms of another tick-borne disease known as granulocytic erlichiosis, and Heliobacter infections in the mouse, a common and serious disease that complicates biomedical research.

Barthold has received research funding from the National Institutes of Health for more than 30 years and has authored nearly 300 scholarly articles, chapters and books. Among many professional awards, he received the UC Davis School of Veterinary Medicine's Alumni Achievement Award in 1998 and the Nathan R. Brewer Award for Career Excellence in Research from the American Association for Laboratory Animal Science in 1996. 


V. Michael Lane

V. Michael Lane

Dr. Michael Lane worked for several years as an engineer before attending the University of Florida where he received his D.V.M. degree in 1980. He served as associate professor at the University of Idaho, with an emphasis in dairy cattle production and ran a private clinical and consulting practice for four years in Idaho with a special emphasis on dairy cattle reproduction and nutrition. Lane joined the school’s Department of Population Health and Reproduction in 1999 and later became the Service Chief for Food Animal Reproduction and Herd Health in the William R. Pritchard Veterinary Medical Teaching Hospital. 

Lane is a diplomate of both the American Board of Veterinary Practitioners in specialty food animal practice and the American College of Theriogenology. He is also a certified nutritionist. As a clinician scientist, Lane brought clinical, epidemiologic and economic perspectives to each case, and in doing so, prepared students and residents to meet the challenges inherent in providing relevant veterinary services to modern food animal production enterprises. He also provided certification in artificial insemination in cattle to increase market appeal for the school’s DVM graduates and offered instruction in new breeding approaches in sheep. 

During his tenure at the University of Idaho and UC Davis, Lane has spent 30 years publishing work in the most reputable journals in his discipline. His papers were emblematic of research from clinician-scientists in the application of modern scientific and analytic methods to solving real-world health problems. For example, he collaborated with a former UC Davis resident to address an important topic in dairy production medicine: what health effects occur, if any, following birth induction in cows that are past their due dates. Their findings impacted future recommendations of standard of care.

Lane’s service expanded to providing scientific and teaching materials to two American servicemen in Iraq and Burkina Faso on agricultural missions. The service member in Iraq, Robert Bonifacio, was a former VMTH resident and MPVM graduate of UC Davis. Lane was recognized by the U.S. Army for contributions to the success of these two missions. 

The Florida Veterinary Alumni Society honored Lane as Alumnus of the Year in 1986.


John Maas

John Maas

Dr. John Maas earned his D.V.M. from UC Davis in 1973 and spent a number of years in private large animal practice before obtaining his M.S. in veterinary microbiology from the University of Missouri in 1980. In subsequent years, Maas served as a faculty member at the University of Idaho and Oregon State University, becoming board certified in both Nutrition and Internal Medicine.

Maas returned to UC Davis in 1988 to join the faculty ranks and worked as a specialist in Veterinary Medicine Extension in beef cattle health and food safety. In this position, he provided statewide extension education and information related to beef cattle production and preventive medicine. Maas’ research included epizootic bovine abortion, anaplasmosis and trichomonosis. He was selected in 2003 as part of a USDA mission to France and the European Union to look at their procedures for dealing with BSE (bovine spongiform encephalopathy) and other animal health concerns.

For more than 20 years, Maas wrote a monthly column for California Cattlemen Magazine which helped keep industry advisors up-to-date and provide them with answers that frequently came from their clients. He was a founding member of the American College of Veterinary Nutrition, serving as president and board chairman; chair of CCA’s Cattle Health Committee; Chair of the National Cattlemen’s Beef Association Producer Education Committee; CCA Second Vice President; and board member for NCBA’s Beef Quality Assurance Advisory Board. 

In addition to his policy involvement in beef cattle organizations, Maas has testified before legislative bodies to protect cattle producers. He has written hundreds of scholarly articles and veterinary articles for beef publications and has been an integral part of California’s Beef Quality Assurance Program since its inception in the early 1990s. His work in coordinating state, regional and national Beef Quality Assurance curriculum for dairy, feed yard and cow/calf BQA programs garnered him the 2013 BQA Educator of the Year Award. As a longtime California beef industry supporter, educator and researcher, Maas was presented with the 2011 Gordon K. Van Vleck Memorial Award.


Peter Woolcock

Peter Woolcock

Dr. Peter Woolcock earned his M.S. in general virology at Birmingham University in the U.K. in 1967 and his Ph.D. in microbiology in 1974 from Leeds University. He served 22 years as an avian virologist with the California Animal Health and Food Safety Laboratory System (CAHFS). Most of his CAHFS career was spent at the Fresno laboratory until its closure in 2009 and relocation to the Davis location. Woolcock served as the section head of avian virology for all of CAHFS.

Woolcock is widely regarded as an authority on viral infections of waterfowl, in particular, duck hepatitis.  Trained as a classical virologist, Dr. Woolcock collaborated with colleagues around the world in developing techniques for the isolation and identification of many avian viruses.  He was responsible for establishing the virus isolation protocol during the exotic Newcastle disease outbreak in Southern California in 2002-2003, and contributed tirelessly to the successful eradication effort.

His field research has led to laboratory discovery of diseases that are of economic importance and consequence to the California poultry and pet bird industries. Examples of these diseases include infectious laryngotracheitis, avian influenza, infectious bursal disease, canary poxvirus, West Nile virus and reovirus. 

Woolcock has contributed numerous book chapters that contribute to avian diagnostic medicine. He was actively engaged in policy making with the California Department of Food and Agriculture and the USDA. He has served as a reviewer for numerous academic journals including Avian Diseases, Avian Pathology, Journal of Applied Poultry Research and many more. Woolcock’s presentations to members of the American Association of Avian Pathologists, CAHFS, the Center for Food Animal Health, and the California Poultry Federation help disseminate cutting-edge information to the state and the nation. 

As a faculty member in the Department of Population Health and Reproduction, Woolcock was actively engaged in mentoring residents, DVM students on CAHFS rotations, undergraduate students on externships and visiting scientists rotating through the CAHFS laboratories studying avian diagnostic sciences.
