Overview

My research explores a particular kind of organized (or structured) knowledge: the links between lexical (word) representations and semantic (meaning) representations. I'm interested in how these systems differ and interact across different languages, especially for bilinguals who not only learn two languages' worth of information, but also deal with conflicts between the ways these languages organize the world. This work includes bilinguals at all levels of proficiency and people who are just starting to learn a language. I use a combination of behavioral methods, computer simulations, and neuroimaging technology (such as MRI and near-infrared spectroscopy) to probe the highly dynamic and interactive cognitive and neural systems that represent linguistic knowledge in humans who speak one, two, or many languages.

Here are a couple of fun popular press pieces related to my research that I've contributed to:
