My research focuses on breast cancer. My laboratory was the first to report constitutive activation of NF-kB in estrogen receptor negative breast cancer. The current focus is on genomic aspects of anti-estrogen resistance, mechanisms of organ-specific metastasis and biomarkers of breast cancer progression and therapeutic response. Results of these studies have been published in more than 80 manuscripts and several have been cited 250 - 630 times (~70 citations per manuscript, H factor=40). I have received funding from NIH (R01, R21, and R03), DOD, and Susan G. Komen for the Cure for these studies. Additionally, a drug identified from these studies is now in phase I clinical trial. I have co-founded a biotech company and licensed another patent to a diagnostic company for clinical use. Two other patent applications are currently pending including one on circulating microRNAs. These outcomes, achieved through extensive collaboration with clinical and basic scientists, demonstrate the translational nature of our research. Based on my scientific contribution to breast cancer, I am one among the 62 scientists selected from seven countries to serve in the inaugural Susan G. Komen for the Cure Scientific Advisory Council (renamed as Komen Scholars).
