Hello! I'm an Associate Scientist at Smith-Kettlewell, where I investigate auditory spatial perception, haptics, echolocation, and assisted mobility in sighted and blind persons. Previously, I completed my Ph.D. at UC Berkeley and postdoctoral work at MIT, where I remain affiliated.
We aim to better understand how people perceive, interact with, and move through the world, especially when vision is unavailable. To this end, the lab studies perception and sensory processing in multiple sensory modalities, with particular interests in echolocation and braille reading in blind persons. We are also interested in mobility and navigation, including assistive technology using nonvisual cues. These are wide-ranging topics, which we approach using a combination of psychophysical, neurophysiological, engineering, and computational tools.
My lab is the home for the Rehabilitation Engineering Research Center funded by NIDILRR with additional support from SKERI and other agencies. Together we address problems of blindness and visual impairment, particularly problems faced by our target populaiton that may be amenable to...
We aim to investigate the nature of auditory perception and how the brain learns rules for interpreting sounds.

What is echolocation? Sometimes, the surrounding world is too dark and silent for typical vision and hearing. This is true in deep caves, for example, or in murky water where little light penetrates. Animals living in these environments often have the ability to echolocate: They make sounds and...
The world is rich in sounds and their echoes from reflecting surfaces, making acoustic reverberation a ubiquitous part of everyday life. We usually think of reverberation as a nuisance to overcome (it makes understanding speech or locating sound sources harder), but it also carries useful...

When blind persons read braille, a system of raised dots for tactile reading and writing, how is the information processed? How do a few indentations on the fingerpads translate to linguistic information, and how does the text, in turn, influence the motions of the...
