Marcel Salathé is generally interested in how human social dynamics affect disease dynamics (and vice versa). After receiving his PhD from the ETH in Zürich, Switzerland, he spent two years as a postdoctoral research fellow at Stanford University where he studied the effect of human contact network structure on infectious disease spread. His research group currently uses complex systems models, wireless sensor network technology and large-scale data sets from online social media sites to analyze the spread of disease and health behaviors on social networks.
