Abhilasha Ravichander

I am a PhD student in the Language Technologies Institute at Carnegie Mellon University. I am very fortunate to be advised by Eduard Hovy and Norman Sadeh.

My research interests lie broadly in robustly representing semantic meaning in text. I think a lot about how to estimate and improve model generalization in real-world scenarios, by ensuring models are capable of the kinds of reasoning necessary to understand natural language. This is also concerned with designing better NLP methodology- how to build high-quality datasets and evaluations that reflect meaningful progress towards language understanding.

Additionally, I am interested in the application of these NLP/NLU techniques for social good- essentially, trying to use technology to mitigate some problems created by technology. Through the Usable Privacy Policy Project, I'm engaged in a multi-disciplinary effort to empower internet users to take back control of their privacy.

For more about my work, please see my publications list.

Outside my research interests, I care a lot about helping women interested in getting started with, or furthering, research in natural language processing—feel free to email me! I would be particularly happy to be able to help students from marginalized groups, or less-privileged institutions.
