Katherine's research interests focus on understanding tuberculosis (TB) burden and identifying opportunities to improve access to quality TB prevention and care. She is the LSHTM principal investigator and modelling lead for the LIGHT Consortium, a cross-disciplinary global health research programme which aims to support policy and practice in transforming gendered pathways to health for people with TB in urban settings, and she chairs the Union’s Gender Equity in TB working group. She also contributes to studies of the spectrum of TB disease, with a particular focus on the contribution of early and subclinical TB to disease burden and transmission, and of diagnostic and treatment pathways, particularly through community-wide screening.

Prior to joining LSHTM, Katherine designed and managed research and surveillance on vector-borne and zoonotic infections, acute respiratory infections, and sexually-transmitted infections with the U.S. Centers for Disease Control and Prevention, and she supported HIV voluntary counselling and testing, cohort studies, and clinical trials with Emory University. She has also consulted for the World Health Organization Regional Office for the Western Pacific on pandemic preparedness and rapid response.
