Research Profile

Research Program

Lab Overview

This lab uses cancer animal models, in particular prostate, head and neck, breast, lung, pancreatic, ovarian and other diseases for understanding pathogenesis and developing novel therapeutic approaches. The staff perform cancer treatment studies including radiotherapy, radio-dynamic therapy, gene therapy, chemotherapy, nanotherapy, and MR-guided high intensity focused ultrasound therapy.
