Qi Laboratory 

- Mitochondria in health and disease

Our laboratory studies the role of mitochondrial quality control and metabolism in neurodegenerative diseases. We combine proteomics and genomics, cell and molecular biology, patient-derived iPS cell culture and diseased animals to investigate the underlying mechanisms by which mitochondrial dysfunction contributes to impaired cellular metabolism, immune response and neurodegeneration.

We also use rationally designed peptide inhibitors of protein-protein interactions and high-throughput screening to develop "mitochondrial medicine" as a therapeutic strategy for the treatment of neurodegenerative diseases.
