I’m a first-year PhD candidate in the Schwartslab of Huji-NLP at the Hebrew University. I’m currently on a full-year research visit at DILL Lab with Swabha Swayamdipta.
I'm broadly interested in how language models form and organize meaning internally: how they encode words, facts, and concepts into structured internal representations. My research investigates this hidden architecture to understand what models know, how they know it, and how leveraging that structure can make them more faithful, efficient, and interpretable.
When I’m not delving into cutting-edge NLP challenges, I’m a passionate Tel Aviv fan, a devoted cat parent, a sea lover, and arguably the most enthusiastic reader around.
