BACKGROUND
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.
TEACHING INTERESTS
Dr. Park currently teaches lecture courses in General Microbiology, Molecular Genetics and Fungal pathogenesis. She also teaches lab courses in Cell biology, genearl Microbiology and Pathogenic Bacteria. In addition, she provides research training to the students in the Department of Biological Sciences.

RESEARCH
Our research focuses on host-pathogen interactions in infectious disease. In particular, we have focused on the pathogenic mechanisms of the opportunisitic human pathogenic fungus, Candida albicans. Candida albicans causes variety of infection with significant morbidity and mortality in a large, diverse population of immunocompromised patients. This suggests that C. albicans possesses unique characteristics that enable it to colonize in the host and cause disease when the host has immune deficiency. Interestingly, C. albicans interacts with oral epithelial cells during oropharyngeal candidiasis and with vascular endothelial cells when it disseminates hematogenously. Particularly, the ability of C. albicans to adhere, invade and injure human endothelial cells and oral epithelial cells is believed as a critical step to establish the infection. Our previous work has demonstrated that some C. albicans mutants with reduced ability to injure oral epithelial cells in vitro have also attenuated virulence in the mouse model of oropharyngeal candidiasis. Therefore, the in vitro epithelial cell interaction model is a great screening tool to identify mutants with virulence defects. Our research has focused on three different categories; (1) C. albicans virulence factors that play key role in host-pathogen interaction, (2) Key regulators (especially singaling cascaed) governing C. albicans virulence, (3) C. albicans response to antimicrobial peptides.
