Multiple Mizzou faculty in National Academy of Sciences
The University of Missouri employs multiple faculty members who belong to the prestigious National Academy of Sciences and one who is a member of NAS's Canadian counterpart, the Royal Society of Canada.
Established in 1863 by Abraham Lincoln, the NAS is a private, nonprofit honor society of distinguished scholars engaged in scientific and engineering research, dedicated to furthering science and technology for the general welfare. The NAS includes the Institute of Medicine, which aims to help government and private-sector organizations make informed health decisions. NAS members are elected on the basis of their original scientific research. Past members include Albert Einstein, Orville Wright and Thomas Edison.
Meet the Mizzou professors who have joined their ranks.
Chemistry and Radiology
National Academy of Sciences member M. Frederick Hawthorne began his career in the chemistry of boron half a century ago. Little information existed on the topic, but Hawthorne envisioned that boron might become the basis of products including pharmaceuticals and nanomaterials. He set for himself the goal of using boron to cure common cancers in part through boron neutron capture therapy (BNCT). Results of Hawthorne’s early tests were positive years ago at the University of California, Los Angeles, but Hawthorne lacked access to a source of neutrons and could not conduct clinical trials.
That changed in 2006 when Hawthorne retired from a successful academic career at UCLA and moved his research laboratory to Mizzou (and Missouri, his childhood home), lured by a rare range of resources that could help him complete his life’s work. Mizzou has a medical school, a veterinary college and the nation’s largest academic research reactor with a neutron beam line dedicated to BNCT. At Mizzou Hawthorne serves director of the International Institute for Nano and Molecular Medicine.
In 2009 Hawthorne received the Priestley Medal from the American Chemical Society. In 2012 President Barack Obama awarded him a National Medal of Science, the highest honor bestowed by the United States to scientists.
Napoleon A. Chagnon was elected to the National Academy of Sciences in 2012 and joined the MU Department of Anthropology in 2013. He is known for his genealogical research, his contributions to evolutionary theory in cultural anthropology and his work in the study of warfare.
Chagnon became a controversial figure in the 1960s for his portrayal of the Yanomamö people of South America, whom he first encountered in the Amazon jungle in southern Venezuela in 1964. The cultural anthropologist’s long-term ethnographic field work with the Yanomamö led him to challenge the commonly held idea that indigenous peoples are fundamentally nonviolent prior to contact with modern societies and white imperialists. His studies documented homicide, infanticide and other violence among the Yanomamö, who were isolated from outside cultures. Chagnon’s 1968 book Yanomamö: The Fierce People is the bestselling anthropological text of all time. Teaming up with ethnographic filmmaker Tim Asch, he produced a series of more than 20 ethnographic films documenting the Yanomamö. Chagnon’s life’s work is documented in his 2013 scientific memoir Noble Savages: My Life Among Two Dangerous Tribes—the Yanomamö and the Anthropologists.
Before joining MU as a Distinguished Research Professor and Chancellor’s Chair of Excellence, Chagnon spent more than a decade outside academia. He retired from the University of California–Santa Barbara as a professor emeritus in 1999. In 2010, he received the Lifetime Achievement Award from the Human Behavior and Evolution Society.
Marilyn Rantz, a Curators Professor Emerita of Nursing, has spent more than 30 years working with seniors and conducting research in long-term care and chronic-illness management. A faculty member at the Sinclair School of Nursing since 1992, Rantz is a national leader in the field of senior health care. She was admitted to the Institute of Medicine, the health branch of the National Academies of Science, in 2012.
Rantz has helped implement the national model Aging in Place, which offers care coordination by nurses to enable seniors to receive health care in their residences, rather than being transferred to nursing homes or acute-care facilities. In 2004, she helped found TigerPlace, a Columbia independent-living center dedicated to creating a healthful quality of life for seniors and an environment of cutting-edge research to help seniors live fuller lives.
In 2012 Rantz earned a Nurse Leader in Aging award from the American Academy of Nursing and the John A. Hartford Foundation. The same year, a research team led by Rantz at the Sinclair School of Nursing received a grant of nearly $15 million for research in avoidable re-hospitalizations among nursing-home residents. She and her colleagues have received more than $35 million in funding for senior health care research.
James Birchler, a Curators Distinguished Professor of Biological Sciences, is among the world’s most highly regarded cytogeneticists — scientists who study the structure and function of cells, especially the chromosomes. Birchler created a technique that allows scientists to break down and engineer small parts of a chromosome. In the future, this technique could allow scientists to introduce multiple disease-resistant and agronomic traits to plants.
Birchler also developed a widely used technology to accurately visualize genes and chromosome features. He made major contributions toward understanding how plant and animal gene expression changes in response to the number of genes present. He was first to recognize that the dosage interaction of “gene regulators,” which control the expression of genes, is far more important than “structural genes” — the genes that make up a protein for the eventual expression pattern. Birchler co-founded the “gene balance hypothesis,” which predicts how genes behave during evolution. The hypothesis has the potential to impact future research in medicine, agriculture and biology.
Birchler joined the MU faculty in the Division of Biological Sciences in 1991. In 2002, he was named fellow of the American Association for the Advancement of Science. In 2007, Northeast Normal University of China gave Birchler the Award for Excellence in Academic Achievements. He became an National Academy of Sciences member in 2011.
In 1972, when Jack Colwill launched MU’s Department of Family and Community Medicine, it was a new specialty he hoped would help alleviate the shortage of primary care physicians. For 25 years Colwill led the department, elevating it to a ranking among the best in the nation. He began with a half dozen faculty members. Today there are over 70. Along the way, he recruited Gerald Perkoff, also an Institute of Medicine member, who died Dec. 25, 2011.
Throughout his career, Colwill has sought solutions to physician-workforce issues. The shortage is especially great in rural areas. Colwill is widely known for his decades-long efforts to expand the health care workforce. He realized that in order for family medicine to make its mark, departments such as his had to train physicians not only as clinicians but also as teachers and researchers. He built a department that is nationally known for performing all three tasks at a high level. In recognition of his work, Colwill was elected to the National Institute of Medicine in 1989.
Though he has retired from teaching, Colwill still practices medicine, and research remains a priority. In 2010-11, when he was 75, Colwill’s papers were published in the New England Journal of Medicine, in the Annals of Family Medicine and in Health Affairs, a general health-policy journal.
Michael LeFevre, a nationally known expert on health policy, was elected in to the prestigious Institute of Medicine in 2011. LeFevre is a lifelong Tiger. He earned a bachelor’s degree in engineering and a medical degree, as well as a subsequent master’s degree, from the University of Missouri before becoming an MU professor and physician. LeFevre heads the clinical activities of the Department of Family and Community Medicine at MU and has held many roles in the institution. As vice chair and director of clinical services for the Department of Family and Community Medicine, LeFevre oversees six practices with more than 110,000 patient visits annually. After caring for patients for nearly 30 years, LeFevre still looks forward to going to clinic, and he still delivers babies.
A national health-policy leader, LeFevre served as co-vice chair of the U.S. Preventive Services Task Force, whose members study medical problems that affect large parts of the population and make recommendations for preventive care. He has published widely on screening for diseases and events such as hepatitis B, aortic aneurysm, oral cancer, suicide risk, vitamin D deficiency and thyroid dysfunction. He also helped develop national guidelines for the treatment of hypertension.
R. Michael Roberts
Animal Sciences and Biochemistry
Curators Professor of Animal Sciences Michael Roberts is best known for his work on biochemical communication between embryo and mother in cattle and other livestock species. He is particularly interested in how the production of embryonic proteins leads to maintenance of pregnancy. Roberts and his colleagues have also developed a dependable and sensitive pregnancy test, which is now commercialized for use in the dairy industry. It’s based on a second embryonic protein that enters the mother’s bloodstream as the placenta first forms. Roberts’ current research uses stem cells to create functioning placental cell types of both livestock species and humans. In the human work, he focuses on the common disease of pregnancy known as preeclampsia, which includes a limited invasion of the placenta into the wall of the mother’s womb.
In 2005 Roberts was named to the Scientific American Top 50 list for accomplishments in research and technological leadership. He also earned the 2006 Carl G. Hartman Award from the Society for the Study of Reproduction in recognition of a research career and scholarly activities in the field of reproductive biology.
Linda Randall, Professor Emerita of Biochemistry, studies how cells know the destination of their thousands of proteins and how those proteins are put in their proper places. She isolates the “machinery” from the bacterium Escherichia coli, taking it apart and putting it back together to learn what each part does. The process involves special channels through membrane barriers, motor components that provide energy to move the proteins and “chaperones” to guide them. The knowledge gained from bacteria can be applied to all cells, including those in humans. Randall and her research group once performed an interpretive dance to illustrate this process. The performance featured black leotards, theatrical lighting and “molecular music” generated on a synthesizer.
In 1993 the National Institute of General Medical Sciences awarded Randall the Method to Extend Research in Time, or MERIT, Award, which aims to reward long-term investigators whose research competence and productivity are "distinctly superior" and to help them continue that work. She was elected to the National Academy of Sciences in 1997.
John Boyer was raised on a small beef cattle farm that he and his brother operated for six years and where he remains active. Because the farm is subject to severe drought on average every three years, he devoted his career to understanding how plants perform in these conditions and whether their performance can be improved.
His work focuses on crop growth, photosynthesis and grain production using tools of biochemistry, biophysics and molecular genetics. His particular discoveries are the biochemistry necessary to reverse grain losses during drought and the specific chemical reactions controlling plant growth rates.
Boyer was elected to the U.S. National Academy of Sciences in 1990 and to the Australian Academy of Sciences in 2005. He has conducted research at the University of Illinois, Texas A&M University and the University of Delaware.
Boyer is a distinguished research professor in the University of Missouri College of Agriculture, Food and Natural Resources and is a member of the internationally recognized Interdisciplinary Plant Group (IPG).
