James Muir

Dr. James P. Muir
Regents Professor
Texas A&M AgriLife Research, Stephenville
Dr. Muir has focused his forage legume research career on the plant-animal interface. His interests encompass the broad picture (ecosystems, both natural and manipulated) and how to maintain systems stability while increasing productivity. Research topics have focused on plant response to herbivory, both in terms of survival as well as primary productivity. In some cases, animal (mostly ruminant) responses to plants and plant communities have been of primary interest. Within the topic of legumes, Dr. Muir has established an international presence that has resulted, in recent years, in invitations to speak and publish review articles in Europe, North America, Africa and South America in English, Portuguese and Spanish. Dr. Muir’s international research encompasses multi-purpose legumes as pulses, cover crops, green manures, revegetation, soil conservation, wildlife, forages, bioenergy, grassland restoration, environmental stability, and biodiversity. Before Dr. Muir came to the Texas A&M System 16 years ago, he had already had a 10-year career in international research and development in Africa. He brought those cross-cultural insights and contacts with him to Texas and continues to expand his international reach. In the last five years he has traveled and worked throughout the world undertaking research, training students and presenting his findings. In the last five years, his research has taken him to, among other countries, South Sudan, Mozambique, Ethiopia, Poland, Australia, Brazil, Argentina, Portugal and Ireland.


Wayne Smith

Dr. C. Wayne Smith
Associate Department Head and Professor
Soil and Crop Sciences
Texas A&M University
Dr. Smith has authored or co-authored 105 referred journal articles that deal with an array of scientific inquiries, from the use of the Bayesian approach for statistical mean separation to documentation of created germplasm/cultivars. He has completed research and published on uniform growth stage descriptions, production practices such as plant spacing with modified phenotypes of cotton, nitrogen rates, recovery from hail damage, double cropping, modified germination tests, impact of plant growth regulators, studies on host plant resistance in exotic germplasms, condensed tannin concentrations, field designs, yield components, root growth parameters, within-boll yield components, and fiber growth parameters. The majority of his energies have gone into the development of improved germplasm lines of upland cotton that were then transferred to the private sector for incorporation into adapted cultivars. He has released or co-released a total of 125 germplasm lines and 4 cultivars. Dr. Smith’s plant breeding ability and releases are recognized worldwide. Wayne was invited recently (October 2013) to present research and breeding results to the International Cotton Advisory Committee in Cartagena, Colombia. First, many if not all of the 125 germplasm lines and 4 cultivars have been used by other public breeders and private breeders in the potential development of new cotton cultivars. He has developed and released germplasm with fiber length and strength that is unparalleled in other upland public programs in the U.S. and continues to work in this area. Dr. Smith takes breeding research to completion as documented in over 100 peer reviewed publications and 129 genotype releases during his career. Dr. Smith’s research efforts would not be complete without noting his efforts to create research opportunities for Texas A&M AgriLife Research plant breeders. Wayne developed and guided through the approval process our distance plant breeding graduate program. This distance graduate program is the first distance delivered Ph.D. offered by Texas A&M University and the first in plant breeding offered in the United States. This program was initiated in January 2013 and promises to create collaboration between our plant breeding faculty and research scientists worldwide by co-mentoring distance graduate students. This program will give our plant breeding faculty



Thomas H. Welsh, Jr., Ph.D.Thomas H. Welsh, Jr., Ph.D.
Professor and Section Leader, Physiology of Reproduction
Department of Animal Science
College of Agriculture and Life Sciences
Dr. Thomas H. Welsh, Jr., is an internationally recognized endocrine physiologist whose major research focus is the investigation of how stress adversely affects the metabolism, immunity, and growth of animals. The central premise is that an appropriately functioning immune system boosts health and promotes efficient use of nutrients by animals, reducing veterinary costs and improving product quality. Dr. Welsh coordinates a team with members across colleges, agencies, and states to develop methods to assess temperament and stress responsiveness in beef cattle. Because of their findings, larger feedyards are incorporating methods for measuring temperament and disposition as they assess and manage incoming cattle. Dr. Welsh and his colleagues also investigate the influence of prenatal stress on postnatal health. Their work is not only relevant for production agriculture but also has implications for human health. The contributions of Dr. Welsh’s team play a key role in the worldwide One Health Initiative, which is based on the premise that animal and human health are inextricably linked. The team has laid the groundwork for epigenomic and translational biology approaches to meet societal challenges that Texas A&M AgriLife Research has a responsibility to address. Throughout his 29-year career in the Department of Animal Science, Dr. Welsh has excelled as a teacher at the undergraduate and graduate levels. He has served on numerous master’s and doctoral committees, including in advisory roles, and is a leader in recruiting underrepresented minorities. He currently holds adjunct appointments to the Department of Veterinary Integrative Biosciences at Texas A&M University and the Department of Animal and Wildlife Sciences at Texas A&M-Kingsville. He has extensively collaborated with Texas A&M University System scientists at Uvalde, Beeville, Kingsville, and Canyon, as well as with faculty at Texas Tech University. His scholarly and service-oriented approach to science brings distinction to AgriLife Research and to the College of Agriculture and Life Sciences.

Dr. Charles M. RushCharles M. Rush
Regents Professor and Research Faculty Fellow
Professor of Plant Pathology
Texas A&M AgriLife Research and Extension Center at Amarillo
Since joining the Texas A&M AgriLife Research and Extension Center at Amarillo in 1986, Dr. Rush has led an internationally respected plant pathology program that fights economically damaging crop diseases in the Texas Panhandle. He has gained international recognition for his program’s work on highly contagious crop diseases. To help control rhizomania of sugar beet, for example, Dr. Rush’s program showed how changes in irrigation could lessen the severity of the disease or even keep plants from becoming infected. These studies were among the first to investigate the relationship between irrigation and plant disease progression. The research helped Texas growers both retain high yields and save water. Dr. Rush’s lab gives tours, helps with school science projects, presents its research at field days, and helps growers diagnose plant diseases. He expanded these diagnostic services by establishing a plant disease diagnostic laboratory as part of the National Plant Diagnostic Network. Dr. Rush has provided diagnostic services to detect the fungus that causes Karnal bunt—a disease that attacks wheat and triticale—and provide Texas farmers with documentation that their crop was disease-free and could be sold. Dr. Rush has distinguished himself as a leader in the field of plant pathology. In the past five years alone, he helped to bring more than $16 million in grants for plant disease research, has served on many review panels in his field, and has contributed to 117 publications. He and members of his research staff are sought-after experts and speakers; his former students have become integral faculty in research facilities across the country. Since 2009, Dr. Rush has served as national program director for the Zebra Chip Specialty Crop Research Initiative, coordinating the efforts of 30 scientists in seven states to study zebra chip disease in potatoes. He and several other members of this team received the Integrated Pest Management Team Award from the Entomological Society of America in 2012. Dr. Rush was named a Texas A&M AgriLife Research Faculty Fellow in 2006 and a Texas A&M University System Regents Fellow in 2007.
