Major Research Interests:  Regulation of the invasion and metastasis of cancer cells, and development of novel therapeutics to reduce or prevent tumor invasion and metastatic disease

The major project in my laboratory involves defining the molecular signaling pathways that regulate the invasion and metastasis of cancer cells. Our current primary focus is on breast and prostate cancer. Invasion and metastasis are complicated processes that are poorly understood, and they are the primary reasons many patients with cancer die. Therefore, a better understanding of these processes will lead to the development of more effective therapies. Our approaches range from 1) basic science to define the role of extracellular tumor environment in regulating changes in lysosome trafficking and cell motility, survival, invasion and metastasis, 2) preclinical testing of novel compounds to block these changes, 3) clinical trials to determine if these compounds actually work in patients with cancer and 4) commercialization of successful compounds.
