My research focuses on understanding the roles of STATs and related transcription factors in breast and ovarian cancer and we use that knowledge to identify drugs to target the pathways associated with these transcription factors. In my lab, we use a 3D culturing system to mimic advanced stages of cancer. Moreover, we use a combination of wet lab experiments and bioinformatics to identify possible drugs for the treatment of breast and ovarian cancer.
