I’m currently working in the area of natural language understanding at Amazon in Seattle, WA. If you have any questions, please feel free to reach me at hayley.uiuc@gmail.com

I did my PhD in Computational Linguistics at the University of Illinois at Urbana-Champaign dissertation. I worked on developing computational methods for low-resource languages with my advisor Prof. Lane Schwartz. My projects also included multilingual language modeling (TACL 2021) and language modeling and dependency parsing for low-resource languages.

In Summer 2021, I worked on long document classification using Transformers as an Applied Scientist Intern at AWS. I worked as a graduate researcher at the 2019 Sixth Frederick Jelinek Memorial Summer School & Workshop on Speech and Language Technology (JSALT 2019) as a member of the Neural Polysynthetic Language Modeling team in Summer 2019.

During my PhD study, I also completed my MS degree in Statistics (Aug 2021). Prior to that, I earned a master’s degree in Teaching English as a Second Language and published research papers in language assessment with Prof. Xun Yan.
