Oliver Kaltz (Directeur de Recherche, CNRS) is member of the ISEM team Experimental Evolution of Communities. Using experimental approaches, he investigates the evolutionary ecology of host-parasite interactions, namely the epidemiology and dynamics of coevolution and coinfection, local adaptation, and the evolution of parasite life history and virulence. He has further been involved in projects on bacterial antibiotic resistance evolution, bacteria-phage coevolution and phage therapy. Recent work has been addressing the role of dispersal, genetic factors and fluctuating environments for epidemics and coevolution in spatially explicit metapopulation settings. He investigates these questions in experimental microcosm populations of microbial model systems, mainly Paramecium caudatum and bacterial parasites of the genus Holospora. Currently, Oliver is coordinating a collaborative French project (ANR 'FEEDME') on eco-evolutionary dynamics in host-parasite metapopulations, combining both theoretical and experimental approaches.
