I am a Research Associate at McGill University. I received my Ph.D. in Cognitive Psychology and Language Science at The Pennsylvania State University in 2015, working with Judy Kroll and Giuli Dussias. After, I moved to Montréal as an NIH-funded postdoctoral fellow at McGill University. I work in Debra Titone's Language and Multilingualism Laboratory

I investigate the cognitive, linguistic, and neural mechanisms that allow people to manage language-related uncertainties that occur in their environments. I use bilingualism as a lens to study these processes because bilinguals become experts in managing language-related uncertainties at multiple levels. My work shows that aspects of language diversity impact neurocognitive and linguistic outcomes.

I use several experimental methodologies in my research, including questionnaires, behavioral responses, eye tracking, and neuroimaging. Recently, I have begun incorporating machine learning and network science as methods to build and test cognitive models of language use and executive control. When combined, these methods are highly suited to revealing neurocognitive adaptations that occur as a function of real-world language experience.

distribution of language entropy across different social contexts french-english bilinguals in montreal. contexts like reading and writing for work purposes have low language entropy. contexts like thinking and dreaming have high language entropy. topic networks and communities by language (dominant vs. non-dominant). networks for the dominant language are larger and have fewer communities. networks for the non-dominant language are smaller but have more communities.
