The Helmholtz Graduate School for Infection Research at the Helmholtz Centre for Infection Research is designed for PhD students at the HZI and their partner institutes. This new school has started in 2009. Under its roof the Helmholtz International Research School (HIRSIB) is located which has already started in 2007. Both schools are supported by the Helmholtz Presedent´s Initiative and Networking Funds and offer a platform for excellent structured training for PhD students containing lectures on main topics in infection, labcourses, symposia, summer schools and thesis committees, supported by a network of supervisors located at different institutes. We are looking for highly-motivated candidates who have an active interest in the complex interactions between host and pathogens.
