I am an Assistant Professor (Senior Lecturer) at the department of Software & Information Systems Engineering (SISE) at Ben Gurion University where I'm heading the NLP and Social dynamics lab (NAS-LAB). I'm also serving as the director of the newly founded interdisciplinary Center for the Study of Digital Politics and Strategy (DPS@BGU) My research mainly involves modeling and analysis of Social Network Dynamics based on various social signals ranging from language use to patterns of online activity. I use Random Graphs, Complex Networks Analysis, Machine Learning and Natural Language Processing in the context of social interaction. I'm interested in large scale-data driven modeling of the processes in which language is shaping and shaped-by social dynamics. In particular, I'm interested in modeling social coordination, influence and contagion in social networks and in the political domain.
