He came to Dr. Byung Mu Lee’s Lab upon finishing graduate courses in the College of Pharmacy, Sungkyunkwan University and spent five years in this lab during his Ph.D. courses. He observed the correlation between chemical carcinogenesis and DNA-adduct formation during his Ph.D. period. He did excellent work during his graduate research by applying his analytical expertise to the studies on the cancer chemopreventive effects of plant polysaccharides on biomarkers associated with multistage carcinogenesis. In addition, he was experienced in various techniques of molecular oncology. After being awarded Ph.D. degree, he went to Korea Food & Drug Administration, and has served as a Senior Researcher thereafter. He has been involved in the adverse effect of Reproductive and Developmental toxicants.
