Research Interests

We are interested in developing and applying cutting-edge ultra high-resolution mass spectrometry-based proteomics and metabolomics technology for biomedical research.
Specifically, my current research is focused on three major directions:

  1. Top-down disease proteomics of myofilaments - deciphering protein modifications for understanding and diagnosis of heart diseases.

  2. Label-free comparative proteomics and metabolomics for systems biology - discovery, characterization and validation of biomarkers associated with human disease.

  3. Characterization of complex post-translational modifications in large proteins (140 kDa) by high resolution tandem mass spectrometry with electron capture dissociation.
