Current Projects

Proximity labeling MS of the Lysosome

Lysosomes are the terminal sites to break down and recycle cellular wastes through the autophagy pathway. We develop novel and improved proximity labeling mass spectrometry methods to study the highly dynamic microenvironment of the lysosomes in a high-throughput and quantitative fashion.


Dynamic Protein Turnover in Neurons

Dysregulated protein quality control is involved in aging and various diseases. We develop dynamic SILAC proteomic methods to quantify protein turnover rates in human iPSC-derived neurons and the changes of protein half-lives under genetic and cellular perturbations. 


Mitochondrial Proteomics and Metabolomics 

Mitochondria are the powerhouses and metabolic hubs of the cell. We develop untargeted and targeted LC-MS-based omics approaches to study the mitochondrial dysfunctions in neurodegenerative diseases.
