About me

I study how information environments shape who takes part in online public discussion and how they engage. The question draws on communication, information systems, education, and economics, and I work across these fields with computational tools.

I am a statistician in the Statistical Methodology Department at the Israel Central Bureau of Statistics. This year I am also a visiting researcher at the Federmann Center for the Study of Rationality at the Hebrew University of Jerusalem, where I work with Prof. Ori Heffetz. I hold a PhD in Information and Knowledge Management from the University of Haifa, supervised by Prof. Sheizaf Rafaeli.

My current work examines how the way evidence is presented in a news article shapes the discussion that follows. Information-rich reporting draws comments that are more reasoned, but it also changes who chooses to comment, and that shift in who takes part matters more for the structure of the discussion than how the same people engage. I combine natural language processing, network analysis, and large language models used as measurement instruments, applied to millions of online news comments.

Related projects ask when open data can be communicated faithfully, how the public adopts and keeps explanations for inflation, and how generative AI can guide readers’ interpretation of data.
