Bio
I am currently a 4th year Ph.D. student in Computational Linguistics at Georgetown University, where I belong to GUCL, NERT, and Corpling. Broadly, my research interests lie in using statistical and computational approahces to study various linguistic phenomena, especially ones that involve non-native English. In particular, I am interested in what language models know (and how we know what they know), and how we can use them to better understand (second) langauge acquisition. For example, I recently worked on comparing native and non-native Englishes in an embedding space using a pretrained large langauge model, and on applying a behavioral approach to a layer-wise probing study of BERT.
Currently, I am working on developing a novel approach to Combinatory Categorial Grammar (CCG) supertagging with Nathan Schneider, and on expanding rhetorical structure theory (RST) by creating and examining an anchored RST corpus with Amir Zeldes.
Prior to joining Georgetown, I obtained a B.A. in Liberal Arts from Soka University of America, where my main focus was Psychology and Economics (although I wrote my thesis on a topic related to Second Language Acquisition!). Subsequently, I pursued an M.A. in Teaching English to Speakers of Other Languages (TESOL) at Michigan State University, where I was co-advised by Sandra Deshors and Kristen Johnson. My M.A. thesis focused on quantifying how Chinese and Japanese speakers' use of the English articles deviates from that of native speakers, leveraging a modeling technique called Multifactorial Prediction and Deviation Analysis with Regressions (MuPDAR).
