News and Kudos from the Department of Physiology and Biophysics
During a 60-minute celebration in the Sanderson Tower Community Room, Dr. Barbara Alexander, the professor of physiology and biophysics at UMMC learned she is the 2023 recipient of the Regions TEACH Prize. This award recognizes annually the "single educator who represents the very pinnacle of Medical Center teaching," said Dr. Rob Rockhold, professor emeritus of pharmacology/toxicology, who announced this year's winner of the five-figure prize.

Dr. Ana Omoto, instructor, recently received two awards.
The first award was presented to Dr. Omoto at the American Physiology Summit in April. She received the Martin Frank Diversity Travel Award. This award program is designed to broaden participation of those pursuing professional career in physiolocial sciences. The specific intent of this program is to increase active participation in and networking at scientific meetings among trainees and early career faculty who are from groups underrepresented in the physiological sciences.
Dr. Omoto is awarded the 2023 Postdoctoral Fellow Research Award from the School of Graduate Studies in the Health Sciences. This award is presented in recognition of an outstanding postdoctoral fellow. The award will be presented to Dr. Omoto at the award ceremony at the end of May.

Excellence in Research Awards
Several members of the department were recognized during a ceremony on Friday, December 9th. The ceremony is held to celebrate investigators most successful at securing extramurally funded original research during their careers at UMMC. Each researcher was presented a framed medallion and a financial award. Pictures below are from the ceremony. Award recipeints from our department are Dr. Erin Taylor, assistant professor; Dr. Alan Mouton, instructor; Dr. Josh Speed, assistant professor.

When Dr. Joey Granger
accepted the role of associate vice chancellor for research this summer, he was adding a seventh position to his current cache at the University of Mississippi Medical Center.
He's also Billy S. Guyton Distinguished Professor, the highest faculty rank at UMMC; dean of the School of Graduate Studies in the Health Sciences; professor of physiology and medicine; and director of three programs: Cardiovascular-Renal Research Center; Center for Clinical and Translational Research; and Hypertension and Cardiorenal Disease Training Program.
A 32-year faculty member at UMMC, Granger says the workload isn't as bad as it seems since there's a lot of overlap, he has a good team that helps run the multiple ships and he loves what he does.

National Postdoc Appreciation Week September 19-23
Dr. John Hall, the Arthur C. Guyton Professor and chair of the Department of Physiology and Biophysics, talked about his luck and life at the University of Mississippi Medical Center’s 2022 Last Lecture April 26 in the School of Medicine.
A preeminent scholar in cardiovascular disease, hypertension and obesity, Hall told students he wouldn’t give “another lecture on acid-base balance or renal physiology.” Instead, he discussed the basis for his success as a scientist and educator.
“Seek the best teachers and mentors throughout your life,” he said. “Lifelong learning should be an aspiration for everyone.”
In his 48 years at UMMC, Hall has taught hundreds of students in his laboratory and thousands in classrooms. He’s also taught countless others around the world. Besides the more than 600 papers he’s written or co-written now in the scientific literature, Hall is the editor of the Textbook of Medical Physiology, now in its 14th edition and translated into 22 languages.

Dr. Yingjie Chen, professor of physiology and biophysics, received a five-year, $2.87 million award from the National Institutes of Health for the project, “Mechanism of PD1 on cardiac inflammation resolution during heart failure development.”
Dr. John Hall, Arthur C. Guyton Professor and Chair of the Department of Physiology and Biophysics, received $387,364 from the NIH for the project, “Cardiorenal and Metabolic Diseases Research Center 2021-2022 supplement.”
Dr. Xuan Li, instructor in physiology and biophysics, received $73,458 from the American Heart Association for the project, “Role of sestrin2 in endoplasmic reticulum homeostasis and cardiac protection during ischemia/reperfusion injury.”
Dr. Erin Taylor, assistant professor of physiology and biophysics, received a two-year, $498,000 from the NIH for the project, “Immune system dysfunction and gut dysbiosis in the pathogenesis of vascular dysfunction in autoimmunity.”
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.
2022 Claude Bernard Distinguished Lectureship Award-American Physiology Society
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. Josh Speed, assistant professor
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. 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.
