I am currently a Ph.D. candidate at Korea University, specializing in the migration and toxicological risk assessment of printing-origin substances in paper-based food contact materials (FCMs). My research focuses on hazardous substances with particular emphasis on their analytical detection using LC-MS/MS and HRMS and subsequent statistical evaluation. My academic background includes experience in food microbiology and antimicrobial resistance, and I have authored and co-authored several research articles across the fields of toxicology, food safety, and analytical chemistry. Currently, I am preparing multiple first-author SCI journal submissions related to chemical migration, and I am actively engaging in international scientific communication through poster presentations and peer reviewer activities. I am open to collaboration and review opportunities in the areas of toxicology, chemical migration, food packaging, risk assessment, and regulatory science.
