Bruno Staszkiewicz Garcia

Current Graduate Student

Bruno is a Ph.D. candidate in Hispanic Linguistics and Linguistics at Purdue University. His research interest is at the intersection of phonetics/phonology and pragmatics, with a focus on politeness and cross-cultural differences in speech act realizations. In his dissertation, he investigates the effects of contextual variables (power, distance, and imposition) on the production and perception of the prosodic correlates of requests and offers in Peninsular Spanish. A second line of research aims to extend the study of politeness expression via acoustic cues to other languages and bilingual populations.

Yuhyeon Seo

Current Graduate Student

Yuhyeon is a Ph.D. candidate in Linguistics at Purdue University. His research interests include cognitive hearing science and acoustic phonetics, focusing on bilingual crosslinguistic influence in speech production and perception. This line of research has two main scopes: long-term crosslinguistic influence over a lifespan and short-term crosslinguistic influence in situations like code-switching. His dissertation project investigates changes in the phonetic and phonological systems over a lifespan, including L1 attrition and L2 acquisition in Korean heritage speakers and long-term immigrants. A second, related project investigates the potential for cross-linguistic phonetic influence in different types of code-switching.
