research summary
Despite major advances in cancer diagnostics and therapeutics, clinical outcomes for many patients remain suboptimal. A major challenge is the genetic and epigenetic heterogeneity of tumors, which drives highly variable responses to treatment across individuals. Addressing this complexity requires a more personalized approach.
Our group focuses on developing and leveraging Patient-Derived Organoid (PDO) models of different solid tumors to:
- • investigate cancer biology,
- • identify alternative actionable therapeutic targets, and
- • establish drug response profiling (DRP) platforms for personalized therapy.
We have already developed annotated living organoid biobanks for studying breast cancer and gallbladder diseases. Additionally, our state-of-the-art DROBAuT (Drug Response testing in Organoids using Bioprinting and Automation Technologies) facility enables us to perform high-throughput drug screening using tumor PDOs. Our long-term goal is to develop more personalized and effective, affordable treatment strategies for cancer patients.
We welcome collaborations and partnerships with academic and industry groups interested in translational cancer research.
