Research/Clinical Interest
Adeno-associated virus gene therapy
The major research interest of my lab is biology and experimental therapeutics of cancer and bone diseases. I have been working in cancer immunology, osteopenia and cancer bone metastasis for over 10 years and published several papers in these fields. With combined experience in these three inter-related fields, we are currently expanding our research efforts to understand the immune mechanisms of osteolytic cancer metastasis and develop novel treatment methods and test them first in preclinical animal models. Using gene transfer apporaches, our studies focus on anti-angiogenic gene therapy for solid tumors, dendritic cell-based vaccines for cancer immunotherapy, and genetically-engineered stem cell therapy for bone defects. In addition, the lab is also focused on basic biology of adeno-associated virus (AAV) and AAV vector modifications to achieve high-efficiency gene transfer and targeting.
