About myself
I am on the job market for an academic or industry position in 2024
Here's the syllabus for a Computational Linguistics course I'm teaching at the University of Washington, Winter 2024: https://uw-ling575-wi24.github.io
I study cognitive semantic approaches to the modeling of causal structure in language for AI interpretability and reasoning. One focus of my work is creating and curating natural language resources for model evaluation across a variety of AI and NLP tasks including causal story induction, physical commonsense reasoning, LLM semantic hallucination detection, and multilingual QA. Graphs are everywhere, and a key question in my research is whether semantic structures (e.g., causal graphs or other symbolic meaning representations) help increase the interpretability of AI systems. My approach to language study adopts perspectives from functional and cognitive linguistics, where a central hypothesis is that participant force-dynamic interactions in the physical world (e.g., an event like 'I dropped the ball') shape both human cognition (something akin to an intuitive physics or other abstract knowledge representation) and also linguistic constructions (grammatical categories associated with complex syntactic form). As such, we can study grammatical form associated with causal meaning and, ultimately, gain insight into human and machine reasoning processes. I was a postdoc at the University of Washington working with Yejin Choi, I have a PhD in Linguistics for research on causal structure discovery, an MSc in Computer Science with emphasis on machine learning and experimental methods, and did internships at Amazon (Seattle and Boston) and Sandia National Laboratories.
