Patient prognosis worsens as cancer becomes invasive, spreading beyond the tissue where it has developed and moving into surrounding, healthy tissues. My research focuses on understanding the biological features and molecular mechanisms of cancers that make them invasive. Specifically, I am interested in esophageal squamous cell carcinoma (ESCC), a very deadly type of esophageal cancer that often invades into nearby organs such as the lungs and respiratory tract. Dysregulated tumor suppressors and oncogenes have been shown to play a role in ESCC. My research involves using molecular biology and innovative cell biology techniques to understand how tumor suppressors and oncogenes cooperate to drive ESCC cells to become more aggressive and invasive.
