Dr Jair Bar is an active physician, head of the Thoracic Oncology service at the Sheba Institute of Oncology. He is also the Deputy Director of the Insitute and the Head of the Israel Lung Cancer Group. Dr Bar heads a basic research lab, focusing on models of lung cancer, studying the tumor-immune system-host interactions and how these can be manipulated to eradiacate lung cancer. He is also a clinical investigator, leading a large number of clinical trials for lung cancer patients, using Immunotherapy and other tools.
