Aya Shiraki is currently an Endowed Professor in Department of Geriatric Cardiovascular Diseases, Saga University School of Medicine. She received her M.D. from Saga University in 2002 and her Ph.D. in 2012. Her doctoral dissertation focused on the anti-inflammatory and antioxidant stress as favorable effects of liraglutide, a GLP-1 analog, in human endothelial cells.
After her PhD, she continued her research in basic science related to cardiology, especially focusing on cardiac metabolism. In 2019, she published a paper showing that GLP-1 analogs alter the metabolic substrate (glucose/fat ratio) consumed by a failing heart, contributing to cardiac deterioration and improvement.
She has published 13 peer-reviewed papers and one commentary paper.
