My laboratory focuses on mass spectrometry-based method development in the following specific areas of proteome research in order to study environmental diseases impacted by innate immunity.
1. Global and targeted discovery of protein-protein/protein-ligand interactions by antibody/affinity based enrichment methods in combination with novel mass spectrometry-supportive chemical cross-linking approaches.
2. Identification and quantitative characterization of protein posttranslational modifications (PTMs) by mass spectrometry- supportive chemical probes.
3. Elucidation of protein structures by mass spectrometry.
4. Quantitative proteomics studies for the discovery and validation of cellular protein targets (bio-signatures or bio-markers)
The focused biological application of my research is to understand the role of lipid rafts and Toll-like Receptors (TLRs) in inflammatory signaling pathways. We focus on studying several environmental diseases impacted by innate immunity, such as atherosclerosis, sepsis, asthma, etc. by mass spectrometry-based novel proteomics tools. In addition, the approaches we develop can be generally applied to any biological systems; hence we also welcome researchers to initiate collaborative research efforts with us.
