Amir Feder

I'm a postdoctoral fellow at Columbia University, working with David Blei. I'm currently also a visiting faculty researcher at Google. In 2025 I'll be joining the Hebrew University as an assistant professor of Computer Science.

I work on language models and causal inference, often for applications in computational social science. My research develops methods that integrate causality into language models, and facilitate scientific inquiry with text data.

I received my PhD from the Technion, where I worked with Roi Reichart and Uri Shalit. Previously, I was an history, economics and statistics student at Tel Aviv University, the Hebrew University and Northwestern University. I was a co-organizer of the First workshop on NLP and Causal Inference (CI+NLP) at EMNLP 2021, and the tutorial on Causality for NLP at EMNLP 2022.
