Anna Carratalà, PhD

Dr. Anna Carratalà is a research scientist in LCE (EPFL), working on characterizing the effects of environmental factors on the ecology and evolution of viral pathogens. The ultimate goal of her research is to anticipate the dynamics of viral pathogens over time and space combining environmental, epidemiological and genetic data. During the last 10 years, Dr. Carratalà has investigated the environmental occurrence and fate of enteric pathogens. She has also developed tools for the source tracking of viral pollution in a wide diversity of environmental samples such as feces, biosolids, surface water, sewage and food, among other. In addition, she has investigated the fundamental basis of virus adaptation to disinfectants (UV radiation) and climatic variables (temperature and sunlight) combining lab experiments, metagenomics and population genetics analyses. More recently, Dr. Carratalà, has been working on applying niche modeling to understand the biogeography of human pathogens. In addition, she has characterized the experimental evolution of human viruses under combined environmental factors showing that viruses readily adapt to temperature but not to sunlight or microbial proteolytic activity. Overall the research conducted by Anna Carratalà, contributes to expand the knowledge on the ecology of infectious diseases interact and (hopefully!) will be useful to anticipate the effect of environmental variations (including climatic changes) on the dynamics of enteric viral diseases.

Stéphane Joost, PhD

Dr. Stéphane Joost is a research and teaching associate at LASIG (EPFL) and leads of a landscape genetics subunit. He pioneered the field of landscape genomics and over the years contributed to the development of statistical methods for performing this kind of studies that later were adopted by researchers all over the world. His expertise in this research field is consolidated by the substantial number of featured works that described adaptation in numerous different organisms, for instance cattle, goat, sheep and plants. Moreover, he contributed to the characterization of the good practices for studies of this kind, for example he investigated the role of resolution in environmental data or identified rules to employ geographic information in an ecological study. Since 2014, Dr. Joost also developed research activities in spatial epidemiology in collaboration with the University Hospitals of Geneva and Lausanne. In particular, he applied spatial statistics to precisely georeferenced health data, investigating the spatial dependence of cardio-vascular risk factors in two urban populations, and analyzing the interaction between genetic susceptibility to high body mass index and the environment.
