Katie DeCicco-Skinner

Associate Professor Department of Biology

Dr. DeCicco-Skinner's research interests include cancer biology, cell biology, and immunology. Specifically, her research is focused on studying two of the major inflammatory pathways in the cell, MAPK and NF-kB, to identify how these pathways become inappropriately regulated as a normal cell transitions into a cancerous state. Her research uses a variety of immunological and molecular biology techniques in two separate cancer model systems, squamous cell carcinoma and multiple myeloma.
