Research Interests

My laboratory focuses on elucidating the molecular mechanisms of drug resistance and metastasis in breast cancer using systems biology approaches. We have generated a unique resource of several chemotherapy and targeted therapy resistant breast cancer cell lines and/or animal models with genome-wide transcriptomic characterization that was validated in drug-resistant breast cancer patient datasets.

Combining our expertise in high-throughput functional transcriptomics/proteomics, cancer cell biology and translational research, we work on the mechanistic understanding of drug resistance development and metastasis aimed at potential translational impact.

Our current research interests include i) understanding the role of extracellular matrix re-organization in chemotherapy resistance in triple negative breast cancer (TNBC), ii) overcoming resistance to anti-microtubule agents by exploiting mitotic cell death and immune activation in breast cancer, iii) elucidating the role of specific Phosphodiesterases (PDEs) in endocrine resistance and metastasis, and iv) constructing and targeting mRNA-noncoding RNA interactome regulating organ-specific metastasis of TNBCs.
