Active Mentor - currently hosting PULSe students for laboratory rotations and recruiting PULSe students into the laboratory; serves on preliminary exam committees

Current Research Interests:

Immunotherapy • bone metastatic tumors • repair of bone in tumor and arthritis models • mesenchymal stem cells

Our laboratory develops strategies that can leverage the immune system to simultaneously repair bone and control inflammation or cell viability. The overall therapy goals are to (a) treat tumors and repair bone in tumor models and (b) treat and repair cartilage/bone in arthritis models. We have several ongoing projects to achieve these goals, including: 1. Targeted therapies such as C-term targeted osteo-immune cytokine IL-27, for which we use gene delivery as a tool 2. Targeting of receptors such as the laminin receptor using small molecules discovered in our laboratory 3. Understanding the biology of mesenchymal stem cells and how to utilize them as therapies.
