Biography

I am a Social Science Research Professional in the Department of Linguistics at Stanford University. I received my Ph.D. in Linguistics at UCLA, where I investigated the sources of individual differences in phonology and used computational methods to model inter-speaker variation. I also investigate phonological development and the characteristics of child-directed speech. Recently, my research draws on linguistic insights to understand the performance of Large Language Models.

If you are a graduate student or a faculty member at Stanford Linguistics, you can schedule a meeting with me here.
