A major focus of my laboratory is the discovery of new drugs for the treatment of cancer, primarily breast cancer and solid pediatric cancers. Our historic focus has been on the identification of novel microtubule-targeting agents from natural products and synthetic chemistry efforts. This work continues and we are also evaluating diverse natural product extracts for activity against specific types of cancer, including the molecularly defined subtypes of triple negative breast cancer and pediatric solid tumors. We conduct the initial discovery in mechanism-based and mechanism blind screens, we use bioassay-guided fractionation, in collaboration with our chemistry collaborators to identify the active constituents, and then we conduct mechanistic studies on the pure compounds and on synthetic and natural analogs.

In addition to our drug discovery efforts, a second major initiative is identifying the molecular mechanisms of action of chemically diverse microtubule targeting agents. While microtubule targeting drugs have been used successfully for decades for breast and pediatric cancers, we still do not fully understand why these drugs are effective and which patients will respond best to the different drugs. We are investigating how these drugs differentially interfere with interphase signaling events important for oncogenesis. I was initially trained in cardiovascular pharmacology and then developed expertise in drug discovery, cell biology and molecular oncology. The long-term goal of our research is to develop more effective therapies for the treatment of cancer.
