Paola E. Dussias is Professor of Spanish, Linguistics, and Psychology at Pennsylvania State University. The research that she and her students conduct employs methodological tools from linguistics, experimental psycholinguistics, and cognitive neuroscience to examine the way in which bilingual readers and speakers negotiate the presence of two languages in a single mind. They also examine the variables that incur processing costs during the comprehension and production of code-switched language. Their work, supported by grants from the National Science Foundation and the National Institutes of Health, has shown that the native language is open to influence from the second language, and that not all code-switches incur processing costs.

Jorge R. Valdés Kroff is Assistant Professor of Spanish and Linguistics at the University of Florida. He is the director of the Bilingual Sentence Processing Lab which uses behavioural and eye-tracking methods to investigate how bilinguals adapt their parsing preferences to better anticipate upcoming code-switches. His recent work focuses on testing whether bilinguals tap into production asymmetries to guide comprehension and recruit greater engagement of cognitive control to rapidly integrate upcoming code-switches.

Michael Johns is a PhD student in Spanish and Language Science at Penn State University. His research focuses on the integration of psycholinguistic methodologies, such as eye- tracking and pupillometry, with insights from sociolinguistic data and bilingual corpora to investigate the processing of code-switched speech. A central theme to his research is the role of input and usage in shaping the processing system, and the interaction between external, social factors, and internal, cognitive factors.

Álvaro Villegas is Assistant Professor in the Department of Modern Languages and Literatures at the University of Central Florida, where he teaches Spanish Linguistics. He earned his PhD in Spanish Linguistics and Language Sciences at The Pennsylvania State University in 2014. His research focuses on Psycholinguistics and Bilingualism, with a special interest in the production and comprehension of heritage speakers. He also works with bilingual communities in Orlando to inform parents and educators about the benefits of bilingualism and to promote bilingual education.
