Dr.Park received her Ph.D. Microbiology from Ewha Womans University (Seoul, Korea) in 2002, followed by postdoctoral training in mycology and molecular biology at the Division of Infectious Diseases, Harbor-UCLA Medical Center. Dr. Park joined the Department of Biological Sciences at Cal State LA in 2008.

研究领域

My research focuses on the molecular mechanisms of fungal pathogenesis using Candida albicans as a model system. Fungal infections have recently emerged as a consistently growing threat to human health, especially in persons whose immune systems are compromised in some way. As a pleomorphic fungus, Candida albicans changes morphologies from yeast, to pseudohyphae, and to hyphae in response to various environmental signals. The regulatory networks governing this process are, however, extremely complex and remain to be completely elucidated. I have dedicated my research efforts to identify key virulence factors governing C. albicans pathogenesis. Our recent research with my research students has discovered that Casein kinase I in C. albicans plays a crucial role in governing morphology transition, cellular integrity, stress response, and host cell interaction by gene deletion analysis. As part of the signaling cascade pathway detecting the environmental changes where C. albicans is placed, Casein Kinase I is believed to interact with various cellular components including transcription factors, which governs that gene expression of the responsive elements. My current research approaches are to elucidate the molecular mechanisms by which Casein Kinae I in C. albicans governs morphology transition and cellular integrity.
