  • Developed high speed chromatin remodeling assay [patent] 

   Assistant Professor: Niigata University School of Medicine/Japan, 2007-2010

      To identify susceptibility genes for endometriosis in Japanese women,                           performed gnenome-wide association (GWA) analysis using two case-                          control cohorts genotyped with Affimetrix Genome-Wide Humen SNP Array 6.0.     

   PHD: Molecular Cell Biology/Niigata University/Japan, 2003-2007                 

      Identified Receptor tyrosine kinase, discoidin domain receptor1(DDR1)                         as potential biomarker and molecular target for advanced ovarian cancer.

    MD: Medicine/Yanbian University School of Medicine/China, 1997—2002                 

       In the first 4 years, took foundational coursework in the practice of                                medicine, bodily systems and diseases. During the last year training program,              rotated through various hospital specialty departments and gained experience in        patient care under faculty supervision.
