As an epidemiologist and mathematical modeller, Katherine aims to generate quantitative evidence to inform tuberculosis (TB) policy and practice. Her current research interests include gender and other structural determinants, strategies to interrupt transmission, systematic screening, the spectrum of disease, and vaccine trial design.

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