Research Interests

Our research interests span from subcellular metabolism to the mechanism of inherited metabolic disease. We aim to 1) discover how a defective lysosome or ER-resident protein contributes to the development of metabolic diseases such as Batten disease 2) Develop molecular tools that allow us to provide cutting-edge knowledge on the ER metabolic composition and better understand their metabolic homeostasis 3) demonstrate novel ER-lysosome contact sites and their functions in cellular homeostasis and 4) develop novel therapeutic strategies and biomarkers for these metabolic diseases. Our experiments are conducted in vivo and in cell culture using several subcellular omics, high-throughput functional genomics, and biochemical techniques.
