==Research interests==

  1. Metastatic Mechanisms of Osteosarcoma: We are investigating integrin mediated and matrix metalloproteinase (MMP) dependent mechanisms of osteosarcoma metastasis.
  2. Sarcoma Biomarker Identification: We are performing proteomic analysis by mass spectroscopy of sarcoma tumor samples using laser capture microscopy and tissue microarrays.
  3. Polymer Scaffolds for Cellular Attachment: We are evaluating cellular attachment to various nano- and micro-scale topologies made with the polymer parylene C.
