The Scope Features UTGSM's Healing, Education and Discovery News

healingGrant Rigney, a University of Tennessee senior in biomolecular engineering and undergraduate volunteer in the UT Graduate School of Medicine Molecular Imaging and Translational Research Program (MITRP), has been named a Rhodes Scholar – the eighth in university history.

Rigney’s research, led by David Blevins, PhD, Assistant Professor of Radiology, and MITRP Director Dustin Osborne, PhD, focuses on the toxicity of PET imaging agents and is patent-pending. Rigney helped develop a test that detects and calculates the concentration of residual phase transfer catalysts in a final radiopharmaceutical product. These toxic elements must be below certain federal limits for use in patients. The current gold standard for testing relies on a subjective visual test. The device created by this research team, which also includes Michael Fang, Research Assistant, and Murthy Akula, PhD, Associate Professor of Radiology, provides quantitative results, allowing for more accurate and automated product testing that better meets stringent FDA requirements for production.

“Grant has been an excellent student in our lab willing to take on a range of projects to expand his own skillset and assist us with our radiochemistry efforts as he works towards his goal of pursuing a medical degree,” Dr. Osborne said.

While Rigney’s research efforts benefit his future career goals, Dr. Osborne said the new technique Rigney helped develop for testing these compounds may eventually have a wide impact on improving how quality control is performed in routine radiopharmaceutical production, benefitting patient care and safety for the nearly 2,000,000 people who receive PET scans every year.

Mitchell Goldman, MD, Assistant Dean for Research said, “Grant’s work is another example of the excellent biomedical research performed at The University of Tennessee Medical Center and the opportunities for UT undergraduates to be part of the exciting research performed by our faculty and advancing medical care for our patients.”

Rigney said conducting research at the medical center under Dr. Blevins and Dr. Osborne has been a formative experience in multiple ways, preparing him to conduct independent research in the future and helping him realize the type of research he hopes to pursue in the future. He said, “After studying for Masters degrees in Global Health Science and Epidemiology and Evidence-Based Social Intervention and Policy Evaluation, I will attend medical school. Ultimately, I hope to be a surgeon and public health researcher.”

“We congratulate Grant and wish him well as he pursues additional research at Oxford,” said Paul J. Hauptman, MD, Dean of UTGSM. “From the vantage point of the Dean’s Office, I’m also more confident than ever that with faculty members like Drs. Goldman and Osborne, the GSM is well positioned to fulfill its mandate to advance medical knowledge through research and discovery.”
