Research Areas:

Ageing is a process of life-long functional decline and is the major risk factor for many human diseases. Instead of treating diseases after they occur, modern gerontology research focuses on the common physiological basis of age-related diseases---the aging process itself, aiming to simultaneously delay the occurrence and progression of one or more age-related diseases, thereby extending an individual's healthspan and lifespan. This is considered as the direction of future medicine and the best measure to address the challenges of an aging population.

Nutritional intervention is the most effective way for healthy ageing. It extends healthspan and lifespan in almost all investigated organisms and improves various health parameters in humans. My laboratory investigates the three dimensions of nutritional intervention---how much to eat, what to eat, and when to eat, by studying dietary restriction, amino acid restriction, and intermittent fasting. We aim to elucidate the mechanisms by which nutritional intervention promotes healthy aging. Interestingly, different nutrient elements in the diet, such as proteins or their building blocks amino acids, fats, carbohydrates, etc., are not equal in producing beneficial effects of nutritional intervention. Amino acids are the most critical components. However, how they mediate the effects of nutritional intervention remains largely unknown.

My laboratory focuses on understanding the molecular mechanisms by which amino acids mediate healthy ageing during nutritional intervention. The research is built around the following specific aims:

1. Characterize individual amino acid effects in response to stress and ageing.

2. Study molecular mechanisms and key mediating nutrients in intermittent fasting.

3. Explore roles of amino acid translation, metabolism, and sensing in healthy ageing.

4. Investigate mechanisms to regulate amino acid sensor Sestrin and move towards its translational research.

These aims of our research are independent but well-interconnected, with an aim to develop novel nutritional interventions that can extend our healthspan and lifespan. Our work will ultimately benefit both healthy and diseased individuals, therefore ameliorating the challenges to the healthcare system posed by population ageing.
