Our lab studies wound healing and skin cancer. In the case of wound healing, we are interested in how the extracellular matrix, a sort of scaffold in the body, can regulate inflammation and scarring in healing wounds. We aim to develop new treatments for poorly healing skin wounds such as leg ulcers. For skin cancer, we are trying to improve a technique called photodynamic therapy (PDT), in which a sensitizing drug (usually a cream) is applied on the skin, and then a laser or other strong light source is used to activate the drug to kill cancer cells. Our laboratory has discovered that when a skin cancer is pre-treated with certain drugs, it becomes much more sensitive to PDT. We hope to make PDT work for thicker and more serious skin cancers.

Our research program involves two thematic areas: (1) wound healing, and (2) skin cancer. For wound healing, we are interested in the role of the extracellular matrix in wound repair. A large carbohydrate molecule called hyaluronan is an abundant component of the matrix and also of the pericellular coats of fibroblasts, epithelial cells, and blood vessels; the addition of certain proteins to hyaluronan after injury appears to be critical for regulating inflammation and fibrosis in healing wounds. Understanding this regulation may provide new ideas for therapy of poorly healing wounds in diabetes.
For skin cancer, we are working to improve a skin cancer treatment called photodynamic therapy (PDT). PDT has two components: a porphyrin precursor that is selectively taken up into malignant cells and converted to porphyrin, and a strong light source that activates the porphyrin inside the cancer cells, producing oxygen free radicals and causing cell death. Under the proper conditions, PDT can also stimulate anti-tumor immunity. We have found that pretreatment with certain drugs and hormones (including methotrexate and Vitamin D) can lead to more porphyrin accumulation, more efficient cell killing upon exposure to light, and improved stimulation of anti-tumor immune mechanisms.
