HEAPHY LAB MISSION
The Heaphy Lab applies an integrated, multidisciplinary approach, which combines tissue-level analysis, cell-based modeling, and molecular and spatial profiling technologies, to define how telomere dysfunction drives the initiation and progression of cancer. Our work spans pancreatic neuroendocrine tumors, prostate cancer, breast cancer, sarcomas, and gliomas.
We aim to translate fundamental discoveries in tumor and tumor microenvironment (TME) biology into clinically actionable biomarkers and strategies that improve cancer risk stratification, prognostication, and therapeutic decision-making.
Equally central to our mission is fostering a rigorous, collaborative, and inclusive laboratory culture. We are deeply committed to mentoring and supporting the professional and personal development of every lab member, empowering the pursuit of impactful, independent, and team-driven research.
