Research Interests

Autophagy is one of the most fundamental cell survival processes that executes numerous homeostatic programs of normal and stressed cells. Dysfunctional autophagy is linked to multiple diseases including cancer, infectious diseases and metabolic disorders. Our lab tries to understand the molecular mechanisms by which autophagy executes its functions in healthy and diseased cells.

The major contributor to acute inflammation is the innate immune systems that gets activated upon microbial invasion or sterile tissue damage. Our lab study the mechanisms of innate immune responses to bacteria, viruses and sterile tissue damages.

Also, we are interested in understanding the crosstalk between autophagy and innate immune responses in autoimmune diseases. In addition we are interested in understanding the mechanisms of cancer progression. Especially, we are interested in the immunological response (esp. type 1 interferons) to cancer.
