RESEARCH SUMMARY

Dr. Madigan is a staff scientist in the laboratory of Samira Sadowski, within the Surgical Oncology Program. He is currently working on uncovering novel driver events and signaling pathways of neuroendocrine tumors (NETs). His research is focussed on expanding our knowledge base regarding the role of abberent epigenetic changes in NETs, which appear to be particularly important for their pathogenesis and progression. Dr. Madigan is also using gene loss-of-function and small molecule inhibitory screens to better inform on focused targeted therapy for NET patients.
