Her research primarily focuses on the interplay between lifestyle factors—particularly diet and sleep—and cardiometabolic health.
She has been conducting clinical studies that explore how sleep duration, sleep timing, meal timing, and eating patterns influence energy balance and cardiovascular risk factors.
Dr. St-Onge’s work has significantly contributed to understanding the bidirectional relationship between sleep and diet. Her studies have demonstrated that sleep can affect dietary choices and that diet may, in turn, influence sleep quality.
Her scholarly impact is reflected in her extensive list of publications and citations, with a Google Scholar h-index of 73, indicating substantial contributions to the fields of obesity, nutrition, and sleep research.
