Associate Prof. Alexander Marson, University of California, San Francisco, US

The goal of Marson’s lab is to understand genetic circuits that control human immune cell function in health and disease. They employ genomic techniques to map epigenetic circuits that establish highly specialized cell identities. Marson’s team have begun to identify autoimmunity risk variants that disrupt immune cell circuits, and how pathogenic circuits may be targeted with novel therapeutics. His lab has developed new tools for CRISPR genome engineering in primary human T cells and they are now pursuing a comprehensive strategy to test how coding and non-coding genetic variation controls functional programs in the immune system. Genome engineered human T cells hold great potential for the next generation of cell-based therapies for cancer, autoimmunity, and infectious diseases.
