The Chief of Staff works as the right hand to the Vice President who leads CHAI's HIV, Hepatitis, and TB cluster, a growing portfolio of three disease programs working with governments, suppliers, communities, partners, and donors. Our work has also expanded into cancer, diabetes, hypertension, and other non-communicable diseases, and we work to accelerate the rollout of lifesaving vaccines, reduce maternal and child mortality, combat chronic malnutrition, and increase access to assistive technology.
