Present Title & Affiliation

Primary Appointment

Assistant Professor, Department of Experimental Radiation Oncology, Division of Radiation Oncology, The University of Texas MD Anderson Cancer Center, Houston, TX

Research Interests

Our goal is to understand how deregulation of developmental signaling (Wnt pathway) contributes to tumorigenesis. Deregulated Wnt signaling leads to various human diseases including cancer. Thus, elucidating the regulatory mechanisms of Wnt signaling to allow for its targeted manipulation will provide a milestone in cancer research. With efforts by biotech producing only limited success to date, there is a critical need to develop novel approaches to block Wnt pathway. A complication is that Wnt signaling is indispensable to homeostasis of normal tissues Thus, the targeting of Wnt signaling regulators whose expression is specifically restricted to cancer provides an opportunity to minimize side effects (normal tissue damage). From unbiased screening and validation, we recently identified several Wnt signaling regulators specifically associated with colorectal cancer. Using genetically engineered mouse models, we are studying the tumorigenic roles of these Wnt signaling regulators in vivo.
