RESEARCH OVERVIEW

My laboratory focuses on trying to unravel the molecular mechanisms that lead to metastatic progression and therapy resistance. We are investigating the link between changes in the tumor microenvironment and melanoma progression, and further, how these changes may affect response to therapy. More recently, we have become very interested in how the aging microenvironment guides changes leading to increased metastasis and therapy resistance, as well as cell-autonomous aspects of therapy resistance, and have demonstrated that normal age-related changes in the microenvironment can contribute to multiple aspects of melanomagenesis and therapy resistance.
