address: Room 329, Lui Che Woo Building, Peking University


Research Interests:

My research interest falls into the area of metabolism and developmental biology. In particular, I am interested in how the adipose and intestinal tissues respond to dietary and temperature interventions at the transcriptomic and lipidomic levels, and the cellular growth pattern and molecular mechanisms that drive and regulate formation of the intervertebral disc during embryonic development. The methods that will be employed to address these questions include, but not limited to single-cell/nucleus sequencing, spatial sequencing, liquid chromatography/mass spectrometry and genetic lineage tracing methods etc. Model organisms to be used include mouse, zebrafish, human and monkey samples etc.
