Research Interests

My main research interests include functional characterization of tumor suppressors and oncogenes in both genetic and epigenetic fields and delineation of the related cellular signaling pathways associated with cancer cell biology. I have particularly focused in cancer cell metabolism and interactions between cancer cells and tumor microenvironment in tumorigenesis, chemoresistance and metastasis of ovarian cancers. These studies give a better insight into the molecular mechanisms of tumor development and tumor progression of ovarian cancers. Our laboratory has established omental conditioned media (OCM) which in addition to the use of next-generation sequencing (NGS) and other omics platforms to delineate the underlying mechanisms and to identify targets in association with clinical obstacles of ovarian cancers. These studies will provide a scientific basis for developing novel diagnostic tools and therapeutic interventions for improving treatment outcome of ovarian cancer patients.
