Welcome and thank you for visiting my website! I’m a PhD candidate in the Linguistics Department at Stanford University advised by Penny Eckert and Rob Podesva. I am currently a dissertation fellow at the Clayman Institute for Gender Research and was previously a DARE (Diversifying Academia, Recruiting Excellence) fellow and Center for Comparative Studies in Race and Ethnicity emerging scholar at Stanford.



As a sociolinguist, my research focuses on how we use language to lay claim to social and political ideologies. My dissertation explores the role of respectability politics in language variation and change among African American women in Sacramento, California. I am also invested in understanding the consequences of linguistic bias, and my previous research includes exploring linguistic bias toward African Americans in education and AI. 

Other Activities 

I worked on a team of incredible researchers at Google from 2020-2024. We conducted foundational research to ensure that voice-AI systems and large language models were more inclusive for African Americans.
