Yale Grammatical Diversity Project: A project that explores the syntactic diversity of North American varieties of English. I have contributed webpages about two syntactic phenomena to this project:

• All the further. Example: Our car broke down, and Croton was all the further we got.
• Subject contact relatives. Example: There was a farmer had a dog.

CogSci Demos: A webpage of demos, developed with Suhas Arehalli, Hongru Zhu, and Tal Linzen, for teaching concepts important to computational cognitive science: https://cogscidemos.github.io/

• Out of Order. Filler-role representations.
  • Based on one of my papers with Tal Linzen, Ewan Dunbar, and Paul Smolensky.
• Who Saw the Bear?. Turkish syntax and morphology.
• Made You Look!. Eye tracking and predictive processing.
• A Stress Test. Parameter-based stress assignment. Written with Ryan Chi.
