Broadly speaking, I'm interested in information; specifically, the relationship between the information which exists in the world and that which exists in our minds. My research focuses on representations of sound information: how the perceptual system turns acoustic information into linguistically and musically meaningful structures, and how this process is modified by experience.
Answering these questions requires the converging use of many methods; my work has included a variety of techniques, including theoretical description, behavioral experimentation, neurophysiological studies, and non‑experimental techniques, such as acoustic and corpus analysis. I also strive to incorporate the best quantitative methods into my work, as robust statistical methods are as indispensable to research as basic measurement techniques.
I approach the research process by attempting to be a synthesizer, in the sense described by E.O. Wilson:
…in the twenty‑first century, the world will not be run by those possessing mere information alone. Thanks to science and technology, access to factual knowledge of all kinds is rising exponentially while dropping in unit cost. It is destined to become global and democratic. Soon it will be available everywhere on television and computer screens. What then? The answer is clear: synthesis. We are drowning in information, while starving for wisdom. The world henceforth will be run by synthesizers, people able to put together the right information at the right time, think critically about it, and make important choices wisely.

Crosslinguistic perception of pitch in language and music
Language and music are both complex systems of organized sound, but the degree to which they share mental representations and resources remains an open question. My dissertation research aimed to contribute to this discussion by examining the effect of language experience on the perception of pitch in musical contexts (and vice-versa).
I seek to determine how perceptual dimensions relevant to the tonal system of a speaker's native language affect the ability to perceive musical melodies. I also attempt to extend these findings to a second language context, and examine the effects of short-term musical training on lexical tone perception.
