Research Area:

The Liu lab has broad interests in exploring the molecular mechanisms that govern the maintenance of cellular homeostasis. Currently, we focus on two major directions: mitochondrial stress response and nutrient sensing mechanisms.

 

Proper maintenance of mitochondrial function is crucial for the survival of organisms. Organisms evolved stress response pathways to survey mitochondrial function and activate repair programs upon mitochondrial stress. Failure to sense or repair damaged mitochondria has been implicated in aging and numerous diseases such as cardiac dysfunction and neurodegenerative disorders. The goal of our research program is to combine the power of worm genetics and biochemistry, to understand and manipulate mitochondrial stress response pathways to promote the healthy survival of organisms.

 

In addition, we are actively exploring molecular mechanisms that enable organisms to sense nutrient availability, which could greatly affects organisms’ reproduction, lifespan and survival.
