HEAPHY LAB MISSION
We employ a multidisciplinary approach encompassing tissue-based, cell-based, and molecular methodologies to investigate the role of telomere alterations in the onset and progression of human diseases, with a particular focus on cancer (e.g., prostate cancer, pancreatic neuroendocrine tumors, breast cancer, sarcomas, and gliomas).
Our overarching goal is to advance the translation of molecular findings from tumors and the tumor microenvironment into clinical tools capable of accurately predicting cancer risk, prognosis, and responses to targeted therapies.
Central to our mission is cultivating a collaborative laboratory environment that supports professional growth and scientific exploration. We are dedicated to promoting diversity and inclusion within academia and medicine, and valuing the development of every member of our team, both personally and professionally.
