I am a board-certified medical oncologist with a practice devoted to treating patients with breast cancer. My laboratory and clinical research both focus on developing new treatment strategies against breast cancers that develop resistance to standard treatments. This involves studies designed to understand the molecular mechanisms underlying resistance and to identify new molecular targets that may inform novel therapeutic approaches.
