The PhD thesis of Kathrin Zürcher covers research studies on tuberculosis that are based on extensive field work and specific data collection within a global research network of HIV cohorts (IeDEA, www.iedea.org). Kathrin studied different aspects of the epidemiology of tuberculosis, especially drug-resistant tuberculosis in HIV-positive and HIV-negative people seeking care in low-and middle-income countries. She examined tuberculosis transmission, the management of tuberculosis from diagnosis to treatment and clinical outcomes, and the evolution of drug-resistant tuberculosis and the clinical consequences. At present Kathrin Zürcher works as a postdoc at ISPM, preparing a Post-Doc Mobility fellowship application to the Swiss National Science Foundation.
