About the role
Job Description
Job Description
ai3Bio’s name nods to the three disciplines it brings to that problem: advanced immunology, autoimmunity, and artificial intelligence. Using its AI platform to analyze diseased tissue, the team found a marker shared by disease-causing Th17 cells across many conditions, giving it a precise way to target them in diseases that have long been treated as unrelated. By resetting the immune system at its root, ai3Bio aims to move autoimmune care from a lifetime of management toward lasting remission for millions of patients. Rather than suppressing immunity broadly or neutralizing one cytokine at a time, ai3Bio is building platforms that eliminate disease-causing Th17 cells, and other classes of inflammatory T cells, in vivo and in a single step
