Nathaniel Weir
I am a final-year PhD student at the Center for Language and Speech Processing at Johns Hopkins University, where I research natural language processing and artificial intelligence. I am advised by Benjamin Van Durme. I am supported by an NSF Graduate Research Fellowship.
I am on the job market! I am looking for both postdoc and industry opportunities. Please reach me at nweir@jhu.edu.
I recently interned with the Aristo reasoning team at The Allen Institute for Artificial Intelligence under Peter Clark. I also interned with Microsoft Semantic Machines under Harsh Jhamtani and with the Deep Learning & Language group at Microsoft Research under Marc-Alexandre Cote and Eric Yuan.
As an undergraduate at Brown University, I worked with Ugur Cetintemel and Carsten Binnig in the Database Group, where we built of the first neural approaches to parsing natural language into SQL.
My research interests include:
- Neuro-symbolic reasoning: combining neural and classical symbolic reasoning to build interpretable, logical, and trustworthy systems
- Natural language generation: creating methods for generating diverse, coherent, and contextually appropriate text according to complex constraints
- Question answering: building systems that can answer complex questions about the world by reasoning carefully over large amounts of text
- Semantic parsing: developing methods for translating natural language into logical forms that can be executed by a computer
