The Tumor Immunology Program investigates the immune system. It also coordinates the UCLA-wide basic and translational immunology curriculum and related research training efforts of its members. 


Understand the immune system in its

  • Basic biology
  • Molecular targeting in lymphoma/leukemogenesis
  • Role in the host response to malignancy
  • Uses in cancer therapy

Meetings and Events

  • Weekly seminars
  • Quarterly Program Group meetings
  • Lectures (UCLA and other institutions)
  • Career development trainee workshop
  • Annual Retreat
  • Symposium on inflammation and cancer
  • Biweekly working group of Tumor Immunology and Thoracic Oncology Program investigators in lung inflammation
  • Biweekly working group of immunoregulatory investigators and clinical investigators in chronic hepatitis, Barrett’s esophagitis and inflammatory bowel disease


Director Dr. Antoni Ribas is a professor of Medicine, professor of Surgery, and professor of Molecular and Medical Pharmacology, Vice-President of the Society for Melanoma Research (SMR) and the Chair of the Melanoma Committee at SWOG. He trained at the University of Barcelona, Spain, with postdoctoral research and clinical fellowship at UCLA. Dr. Ribas is an elected member of the American Society of Clinical Investigation (ASCI). He has published over 200 manuscripts on laboratory and clinical research in malignant melanoma. As a physician-scientist, Dr. Ribas has a NIH and California State-funded laboratory where he conducts research focusing on adoptive cell transfer with T cell receptor (TCR) engineered lymphocytes, anti-CTLA4 antibodies, anti-PD-1 antibodies, BRAF-targeted therapies and nanoparticle-siRNA therapeutics.

Co-Director Dr. Jonathan Braun is a professor and the chair of the Department of Pathology and Laboratory Medicine. His research program is devoted to mucosal host-microbial interaction, using multi’omic and bioinformatics strategies to uncover mechanisms that link human genetic disease variants, and microbiome composition and function in mucosal immune regulation and microbiome-mediated cancer pathogenesis. A leader of interdisciplinary initiatives in immunologic diseases, his current activities include the interplay of host genetics and enteric microbiota composition in inflammatory bowel disease (IBD) with the NIDDK IBD Genetics Consortium, NIH Human Microbiome Project 2, and the Crohn’s and Colitis Foundation Association Microbiome Consortium. At UCLA, Dr. Braun previously directed the UCLA CTSA, and as chair of the Department of Pathology and Laboratory Medicine, is responsible for the integration of clinical care with systemic research services in support of biospecimen-based translational research. This broad scientific expertise and management experience is key to the diverse program-building, operational and educational activities of this program.
