Research Focus

Our mass spectrometry lab is equipped with state-of-the-art mass spectrometers. My research is focused on biomarker discovery relevant to cancers and other diseases from serum, tissue and body fluids, using advanced liquid chromatography coupled nano-electrospray tandem mass spectrometry technique. I also collaborate with other researchers to develop effective mass spectrometry methods for protein identification and post-translational modification characterization.

Current Projects

■ Protein painting identifies therapeutic targets at protein-protein interfaces. The goal is to use protein painting to discover and validate therapeutic target hotspots for cell surface receptors, cancer cell signaling, oncogene/suppressor genes, and immunotherapy targets.

■ Microparticles for directing immune cell trafficking: The goal is to develop a nanoparticle technology based on a hydrogel incorporating affinity baits capable of controlled binding and release of chemokines, providing a predictable manipulation of the lymph node cellular composition.

■ Novel biomarkers of lung cancer to guide prevention and early diagnosis: The goal is to develop a quantitative MS assay for previously identified risk markers that are functionally involved in inflammation, genetic instability, autophagy, oxidative stress and innate immunity.
