Biography

Research Interest: Tumor Fibrosis

My research interest focuses on understanding the biology of the fibrotic tumor stroma in pancreatic cancer. Pancreatic cancer is a rapidly progressing, incurable disease that has demonstrated unusual resistance to standard therapies including chemotherapy, immunotherapy and radiation. The current understanding is that the dense tumor stroma fosters tumor cell growth and survival by creating an immunosuppressive microenvironment, and it protects tumor cells by acting as barrier to therapeutic drug delivery. Understanding the relationship between the fibrotic tumor stroma, tumor cell growth, and the inhibition of drug delivery is essential for the development of novel treatment therapies. Specifically, my research is dedicated to investigating the use of immunotherapy to facilitate the degradation of key components of the tumor stroma. My goal is determine which tumor stroma proteins contribute to this therapeutic barrier and to develop therapies that specifically degrade those proteins, allowing for more effective therapeutic delivery. My interest in the fibrotic tumor stroma stems from my graduate work on the pathogenesis of skin fibrosis, and I am contining my work on fibrosis as an investigator at Mansfield University.
