Research Summary 

Our lab is currently working on Neuroblastoma, a pediatric cancer, and breast cancer.  The long-term goal of our lab is to identify novel biomarkers and potential drug targets for treatment of cancer. We utilize a wide range of methods including mass spectrometry, gene array, Western Blots, qRT-PCR, microscopy, and migration and invasion assays. A collaborative project with Dr. Fornaro and Dr. Gasiorowski labs involves using genomics and proteomics to study genes and proteins involved in enhanced peripheral nerve regeneration on topographical surfaces.
