Marcel Salathé is interested in how human social dynamics affect disease dynamics (and vice versa). He has a PHD from ETH in Zurich, Switzerland, and did a postdoc at Stanford University. His research group at Penn State University 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.
In 2013, he lead the development of the MOOC "Epidemics - the Dynamics of Infectious Diseases", which is still ranked the Nr. 1 Science MOOC by learner vote on the MOOC review website coursetalk.org.
