Bruno Gonçalves

Is a tenured faculty member at Aix-Marseille Université with a strong expertise in using large scale datasets for the analysis of human behaviour. After completing his joint PhD in Physics, MSc in C.S. at Emory University in Atlanta, GA in 2008 he joined the Center for Complex Networks and Systems Research at Indiana University as a Research Associate. From September 2011 until August 2012 he was an Associate Research Scientist at the Laboratory for the Modeling of Biological and Technical Systems at Northeastern University. Since 2008 he has been pursuing the use of Data Science and Machine Learning to study human behavior. By processing and analyzing large datasets from Twitter, Wikipedia, web access logs, and Yahoo! Meme he studied how we can observe both large scale and individual human behavior in an obtrusive and widespread manner. The main applications have been to the study of Information Diffusion, Behavioral Change and Epidemic Spreading. He is the author of almost 50 publications with over 2700 Google Scholar citations and the editor of the forthcoming book Social Phenomena: From Data Analysis To Models (Springer, 2015).
