My Research

My research program comprises two main themes: bilingual language processing and the neurocognitive mechanisms of reading.

Bilingual Language Control 

Although it is estimated that more than half of the world’s population is bilingual or multilingual, the cognitive processes that these individuals use to monitor and select the appropriate language for comprehension and production remain unclear. Language selection is a critical skill for bilinguals in their daily lives to ensure efficient communication with interlocutors who have a variety of language backgrounds.

The majority of our research focuses on the underlying neurocognitive mechanisms of bilingual language control that prevent the unintended language from overtly interfering with the use of the intended language. We use behavioral, eye-tracking, and electrophysiological (EEG/ERP) methods to assess how bilinguals retrieve linguistic information from long-term memory during language processing.

Neurocognitive Approaches to Reading

Another major theme of my research program concerns reading processes in monolinguals and bilinguals to examine how various levels of linguistic representation (i.e., orthography, phonology, semantics, syntax) interact during sentence processing. The ultimate goal of this work is to better specify how visually extracted information from text progresses through the language processing system to produce the outcome of successful (or unsuccessful) comprehension. 

In one major line of this research, we design and implement experiments to test different models of eye movement control during reading. Current work in progress examines the role of parafoveal processing (i.e., to the right of the currently fixated word) during reading in native and non-native readers. This research aims to answer questions about how readers with different linguistic backgrounds extract information from text for successful comprehension.
