• I am interested in studying the factors that determine the persistence and evolution of host-parasite systems, with emphasis on the ecological determinants that influence the evolution of infectious diseases. In particular, my research focuses on the study of the ecological, historical and geographical factors that influence the wild transmission of Trypanosoma cruzi in Chile, and its potential applied consequences. To this end, I use field, experimental, and molecular procedures.
