He received his Ph.D.(Ohio State University, USA) working with Paula Sundstrom on the cAMP signaling pathway of a human fungal pathogen Candida albicans. In postdoctoral studies with Joseph Heitman (Duke University, USA), he investigated the molecular mechanisms of various stress sensing signal cascades that affect the virulence of another human fungal pathogen, Cryptococcus neoformans. He became an independent researcher as a faculty member at Soongsil University (South Korea) in 2006 and moved to his current position in Yonsei University in 2008. Stemming from his research background, his current focus is on genome-wide, comprehensive understanding of complex signaling cascades that govern growth, differentiation, stress response, and virulence of human fungal pathogens by using C. neoformans as a model system.
