Miriam Merad, MD, PhD

Dr. Merad, MD, PhD, is an expert in DC biology and has been studying the role of DCs in tissue for more than ten years. As Director of the Precision Immunology Institute at Mount Sinai and Professor of Oncological Sciences, Dr. Merad made key contributions to our understanding of the regulation of DC development and function and has identified the origin and functional diversity of the phagocyte pool in the intestine, with implications in cancer immunotherapy. Dr. Merad is also the Director of the Human Immune Monitoring Center at Mount Sinai School of Medicine (MSSM) which goal is to identify novel immune biomarkers of disease and response to therapy in patients with cancer, allergic disease, or viral infection. She is the recipient of numerous NIH awards for consortium-based efforts related to immune monitoring of vaccines, including in cancer, and for developing sample-sparing immune monitoring techniques. As part of the MS-CIMAC leadership team, Dr. Merad will be responsible for the design of the experiments planned for each trial, data review, and the overall coordination of the project design.

Sacha Gnjatic, PhD

Dr. Sacha Gnjatic, PhD is a Professor and the Associate Director of the Human Immune Monitoring Center at the Icahn School of Medicine at Mount Sinai. Dr. Gnjatic’s lab focuses on human immune responses to cancer in an antigen-specific manner, in the periphery and at the tumor site, to define new targets for the development of cancer immunotherapies, how they work and why they may fail. Dr. Gnjatic’s work on tumor antigens has established the immunological basis for testing cancer vaccines in over 40 clinical trials, opening a new field of cancer immunology based on clinical discovery, with the goal to achieve protective integrated immune responses in the fight against cancer. Dr. Gnjatic’s laboratory has pioneered novel high-dimensional techniques and served as reference for harmonized immunomonitoring of humoral, cellular, and tissue-based immune correlates, which has led to the adoption of new standards by other labs.
