Our works focus on proteomics and peptidomics in various organisms to novel studies for application. Our research is working on expression proteomics (proteome, phosphoproteome and glycoproteome) and peptidomics; functional proteins and antimicrobial peptides studies in several biological subjects by molecular techniques.We are also focusing on the comparative proteome profiling of plants (eg. para rubber tree) to identify and characterize immune-responsive proteins, antimicrobial proteins and peptides in several tissues including rubber latex and skim latex (waste) during microbial infection especially fungal infection in many economic plants.In addition, besides plant and its waste, we are focusing on crustacean (shrimp and crab) innate immunity via each hemocytes (blood cells) cell type after pathogen infection. Gel-based proteomics and proteomics-based approach are utilized to understand the roles of immune-related proteins and peptides in host defense mechanism response. We aim to discover the effective and sustainable way to protect the shrimps from pathogen infection especially viral infection.
