Cancer Research Interest

• Research Interest Statement: My lab is focused on musculoskeletal regenerative medicine, with particularly emphasis on the appendicular skeleton (long bones and synovial joints). Within this general theme, there are multiple directions with relevance to cancer therapy. For example, we are interested in improving the management of skeletal defects that result from surgical tumor removal or radiation therapy. Some of this work involves the application of culture-expanded mesenchymal stem cells and their secreted extracellular vesicles for improving defect repair; for patients that have undergone cancer treatment, it will be critical to understand the potential of these exogenous biologics for promoting cancer recurrence. In addition to stem cell-based therapeutics, we are also developing drug delivery strategies that target cartilage; such strategies have the potential to improve drug targeting of skeletal cancers (e.g., chondrosarcoma, osteosarcoma).
