Since Nov. of 2016, he joined to Center for Genomic Integrity (Institute for Basic Science, UNIST, Ulsan) as a Principal researcher and has investigated for MS-based proteomics (Orbitrap Fusion Lumos system) / metabolomics analysis for understanding about molecular mechanisms of DNA damage & repair system in organisms. He was also selected as an Early Career Researcher (ECR) of Rep. Korea in the 2018 Human Proteome Organization (HUPO). He has developed chemoproteomics with SILAC-CETSA approach to obtain On-target / Off-target profiles of interesting new molecule entities (NMEs) and investigated drug targets for various types of indications.
Orbitrap Fusion Lumos [Thermo Fisher Scientific ]
The Orbitrap Fusion Lumos Tribrid Mass Spectrometer is designed to expand performance in advanced proteomics, biopharma and metabolomics applications, including quantitation using isobaric tags, low level PTM analysis, data independent acquisition (DIA), and top down proteomics. The new instrument features enhanced sensitivity resulting in improved analyte detection, characterization and quantitation, enabling scientists to perform more comprehensive sample analyses faster and with better accuracy than ever before. The system is the research-leading high performance mass spectrometer with enhanced sensitivity facilitated by a new High Capacity Transfer Tube, Electrodynamic Ion Funnel, Advanced Quadrupole Technology, Advanced Vacuum Technology, and ETD HD.
