Sandro is an Associate Professor in the Department of Pathology at Brigham and Women’s Hospital, at Harvard Medical School. He practices neuropathology with a focus on diagnosing and characterizing adult and pediatric brain tumors. He is a member of the Ludwig Center at Harvard, the Harvard Program in Therapeutic Science, and the HMS Laboratory of Systems Pharmacology. His research laboratory develops and implements methodologies to image tissues resected from cancer patients, extracting molecular information that sheds light on how cancers form and then develop their most aggressive features. With these tools, his group explores the biological properties of cancer tissues, the molecular systems tumor cells use to evade immune surveillance, and the ways that cancer and immune cells assemble into dynamic ecosystems. This rich imaging data is being made available in the form of interactive tumor atlases as part of the National Cancer Institute’s Human Tumor Atlas Network (HTAN), a consortium which is assembling 2D and 3D maps of human precancers and cancers which can be browsed and analyzed by users in research and clinical practice to advance our understanding of cancer and to find new treatments.
