- Senior Lecturer
I am anAssistant 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). 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.
I was a postdoc and a research fellow at Harvard's SEAS & IQSS jointly with the Lazer Lab at the Network Science Institute of Northeastern University.
In my graduate studies I was working with Prof. Ari Rappoport at the CS department in the Hebrew University, mainly on Content Analysis of Social Networks. I studied various aspects of user generated content, such as Amazon product reviews and Twitter tweets, trying to predict the helpfulness/quality of reviews, predict the popularity of memes and extract indirect emotions such as sarcasm to allow more accurate sentiment analysis.
