Understanding and Targeting Cancer Cell Invasion and Metastasis

Research Description

Research in Dr. Diaz’s laboratory focuses on understanding the cellular mechanisms that mediate the malignant behavior of cancer cells with the goal of utilizing this knowledge to uncover novel therapeutic targets to restrain metastasis. Dr. Diaz has investigated how the tumor microenvironmental conditions, including reactive oxygen species (ROS) and hypoxia promote cancer cell invasiveness. She has a deep understanding of the signaling mechanisms that regulate cancer biology, in particular those that mediate cell-cell communication and redox signaling in cancer cells.
