Project Title: Modeling the immunological host-pathogen interaction of Johne’s disease to understand its pathology and treatment
Gesham Magombedze (Ph.D. Applied Mathematics, National University of Science and Technology, Zimbabwe, 2009) develops mathematical models to understand the major factors involved in Mycobacterium avium subspecies paratuberculosis (MAP) infection and host interaction in order to enhance understanding of resistance and susceptibility patterns between pathogens and persistence of infection.
Upon completing his fellowship at NIMBioS, Dr. Magombedze accepted a Research Associate position in the Department of Infectious Disease Epidemiology, School of Public Health, Imperial College, London.
