Biography

Dr. Tan's research focuses on applied physiology, nutrition, and metabolism in healthy individuals and in athletes. Specifically, her interest is in the influence of dietary interventions that manipulate nitric oxide bioavailability and the associated effects on human exercise performance and markers of health.

Dr. Tan has investigated the efficacy of dietary nitrate supplementation, administered by nitrate-rich beetroot juice, on the physiological responses during exercise and its ergogenic potential measuring from the cellular to whole-body level. She has also investigated other nutritional ergogenic aids, such as N-Acetylcysteine, on further elevating nitric oxide bioavailability.
