About Us


PEER is a Youth STEM promotion program for rural middle schools and high schools using veterinary medicine and environmental issues to stimulate youths’ interest in learning about their own health (“One Health”).

In keeping with Vision 2020 outlining the goals of Texas A&M University, PEER has directed its overarching goals toward four of 12 main TAMU Vision 2020 Imperatives. PEER helps the Texas A&M College of Veterinary Medicine & Biomedical Sciences “Meet Our Commitment to Texas”,” Build Community and Metropolitan Connections”, “Increase Access to Knowledge Resources”, and “Diversify and Globalize the A&M Community”.

PEER has developed a website hosting standard-based science and agriculture sciences lessons (some of which are student-centered and others are integrated with English, social studies, and math). PEER offers videos of scientists’ and veterinarians’ presentations and their interviews, teacher professional development statewide, and near peer mentoring of K-12 students. These videos and those of veterinary students and undergraduate students presentations and interviews promoting STEM as they describe their own academic paths toward veterinary school or medical school also can be seen at PEER at TAMU YouTube. The PEER project has reached 20,250 teachers and 2,046,250 students in all 50 states (see maps below) over its 20-year existence and is currently reaching over 2,000 teachers and over 200,000 K-12 students (52% minority) yearly.

Funding for the PEER Program has been provided by the National Science Foundation, National Institute of Environmental Health Sciences, and National Institute of General Medical Sciences (SEPA) of the National Institutes of Health, the Emma Barnsley Foundation and the John Deere Foundation, and the Provost’s Office of Texas A&M University.

ABOUT Christine Budke

Dr. Christine Budke is a professor of epidemiology and associate department head at the Texas A&M College of Veterinary Medicine & Biomedical Sciences. She obtained her veterinary degree (DVM) from Purdue University and a PhD in epidemiology from the University of Basel. Her research focuses on the epidemiology and burden of Neglected Tropical Diseases and Neglected Zoonotic Diseases. These diseases are common in regions of poverty and are considered neglected in terms of research and intervention focus. Many of these conditions not only affect human health, but also affect livestock health, resulting in a secondary social and monetary impact on poor agricultural and pastoralist communities. Dr. Budke has acted as a resource advisor for the World Health Organization Foodborne Disease Burden Epidemiology Reference Group and has contributed to the Global Burden of Disease Study. She is a Deputy Editor of the journal PLOS Neglected Tropical Diseases and an Associate Editor of the journal Preventive Veterinary Medicine. Her research has resulted in authorship of more than 100 peer-reviewed publications. Dr. Budke teaches epidemiology and public health at the undergraduate, graduate, and professional student levels and is the recipient of the Bridges Teaching and Service Award and the Texas Veterinary Medical Association Teaching Award.


ABOUT William Klemm

Dr. Bill Klemm began his professional life as a veterinarian (a graduate and Distinguished Alumnus of Auburn University). He then served a stint in the U.S. Air Force and rose to the rank of Colonel in the USAF Reserves, which included Research and Development planning for Systems Command. He completed a Ph.D. in biology at the University of Notre Dame. He served three years teaching physiology and pharmacology at Iowa State University before transferring to the Department of Biology, specializing in neuroscience, before transferring to the College of Veterinary Medicine. His neuroscience research has spanned the field from membrane biology to human cognition. He has authored over 250 peer-reviewed publications, 55 book chapters, and 22 books (four of the books are on learning and memory). He has served on the official Editorial Boards of twelve scholarly journals, six of which are education journals. He leads a “Neuro-education” group on LinkedIn. He helped create PEER, has been a co-leader of the PEER program since its inception, and written much of the curricular material. He operates a Memory Medic blog at Psychology Today. His blog posts have over 3.5 million reader views. His web site is http://thankyoubrain.com.
