Short Bio

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). 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.

Prospective students: email me if you are interested in what I do (browse around and also check out my (research statement) and looking for an advisor/lab/project. Support is available for excellent candidates.

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.

I was also working on computational aspects of natural language semantics and its application to non-native speakers and on Language modelling of product reviews, books in particular.

In the industry I was working as a SW engineer at the Intel corp. Jerusalem, doing R&D in the ICGJ center, as a product manager at NST (a VoIP startup company), as a scientific intern at Yahoo! Research, and in the Machine Learning and Data Mining group at IBM research (I was working on that).

My 15 minutes of fame:
Our sarcasm detection algorithm was selected by Time Magazine as one of the
50 Best Inventions of 2010. (Here is pop sci talk [HEB])
