Our laboratory focuses on understanding the roles of mitochondrial quality control and metabolism in neurodegenerative diseases. We use unbiased proteomics and genomics, cellular and molecular biology, patient iPS cells-derived cell culture and diseased animals to investigate the fundamental mechanisms by which mitochondrial impairment contributes to cellular metabolism disturbance and neurodegeneration.
We also utilize rationally designed peptide inhibitors of protein-protein interactions and the high throughput screening approach to developing “mitochondrial medicine” as therapeutic strategies for treating neurodegenerative diseases.
