Ageing is a process of life-long functional decline, and is the major risk factor for many human diseases. The world population is ageing dramatically, posing a great challenge for our healthcare system. Research from the ageing field has demonstrated that the ageing process can be ameliorated by various genetic and environmental interventions. Dietary restriction (DR), reduced food intake without malnutrition, is the most effective intervention to lengthen healthspan and lifespan in animals and most likely also in humans. Interestingly, different nutrient elements in the diet are not equal in producing the response to DR. Protein, or its building blocks amino acids, has been shown to be most crucial. Restriction of specific amino acids, e.g. methionine and the branched-chain amino acids (BCAA) leucine, isoleucine, and valine, induces health benefits and is itself sufficient to extend lifespan. However, the underlying molecular mechanisms are still largely unknown. Therefore, my lab focuses on understanding the underlying molecular mechanisms of amino acid-induced healthy ageing and developing new strategies to extend healthspan and lifespan.

Research Interests
Our lab combines chemical defined diet, genetic tools with metabolic and genomic analyses, using culture cells, fruit flies, and mice as models, to study mechanisms of healthy ageing and develop novel health-promoting interventions. The research is built around the following three specific aims:
1. Characterize individual amino acid effects in response to stress and ageing,
2. Explore novel mechanisms in amino acid translation, metabolism, and sensing,
3. Investigate mechanisms to regulate Sestrin activity and move towards Sestrin translational research.
These three aims of our research are independent but well-interconnected. We believe that our work will ultimately benefit both healthy and diseased individuals, therefore ameliorating the challenges to the healthcare system posed by population ageing.
