2021

Excellence in Research Awards Program has recognized investigators who have attracted significant extramural funding and who have advanced science through their distinctive research programs. Medallion Awards are based on the total amount of qualifying extramural funding received by the investigator.

Dr. Robert Hester, Billy S. Guyton Distinguished Professor and professor of physiology and biophysics, will be the 2022 recipient of the American Physiological Society’s Claude Bernard Distinguished Lectureship Award. Hester, a member of the UMMC faculty since 1985, is the primary architect of HumMod, a computer and mathematics-based tool for modeling human physiology. In addition to its expansive research utility, Hester uses the simulation to teach students how to apply physiologic principles and enhance their understanding of acute and chronic conditions throughout the body. Hester also developed a related education package, “Just Physiology,” based on HumMod.

One of those researchers is Dr. Joshua Speed, assistant professor of physiology and biophysics, who received an R01 grant from the National Institutes of Health to study the role of endothelin-1 in obesity and insulin resistance.

Endothelin-1 is a “small peptide produced in blood vessels,” Speed said. “Its production is increased in obesity, and this increase leads to insulin resistance and dyslipidemia” but researchers are not certain why.

With the new grant, his laboratory will study how changes that happen in obesity “disrupt the cellular crosstalk, especially in liver tissue, where we also see an increase in fatty acids in obesity.”

Speed is also interested in the effects on muscle, where cell-signaling molecules called adipokines help manage sugar and fat metabolism.

Dr. Hester’s research has led to a greater understanding of human physiology.

He “has made outstanding contributions to the field of microcirculatory physiology,” said Dr. Joey Granger, dean of the School of Graduate Studies in the Health Sciences, professor of physiology, and director of the Cardiovascular-Renal Research Center.

Dr. Thomas G. Coleman, UMMC professor emeritus of physiology and biophysics who Dr. Richard L. Summers, UMMC associate vice chancellor for research, described as a “revolutionary thinker” in biomedical research, died Feb. 27. He was 80.

Summers said Coleman, who spent his entire career working and teaching at UMMC, was one of the first in the world to use computer models and simulations to perform physiologic systems analyses.

Hester,-Robert-2019-HR.jpg Dr. Robert Hester, professor

Dr. Robert Hester, professor of physiology and biophysics and interim chair of data science, has been inducted into the College of Fellows of the American Institute for Medical and Biological Engineering.

Comprised of the top two percent of medical and biological engineers, the AIMBE College of Fellows honors society members who have made outstanding contributions to engineering and medicine-related research, practice or education; are pioneers in new and developing fields of technology; or who have advanced traditional areas of biological engineering.

Hester was nominated and elected by his peers for his “significant contributions in renal and cardiovascular research, professional society leadership and physiological modeling environment development.”
