My current research activities focus on how augmented communicators interact with each other in real time and how communication technologies can be designed to improve performance. I am a partner in the Rehabilitation Engineering Research Center for Communication Enhancement (AAC-RERC) http://aac-rerc.com. I am also the director of University at Buffalo's Signature Center for Excellence in Augmented Communication (ubceac@gmail.com).
