https://orcid.org/0000-0001-9886-8104Biography
Alexandra Richards is a Research Associate based in the Department of Public Health. She completed her PhD at London School of Hygiene and Tropical Medicine, where she focussed on understanding the natural history of tuberculosis (TB) to create a new model structure for TB transmission models and to understand the impact of asymptomatic disease case finding outputs. After finishing her PhD, she continued working at LSHTM with the LIGHT consortium, understanding the impact of addressing disparities in treatment coverage and risk of disease in men.
