I design and develop interactions and technologies that embrace digital and physical experiences. I am specifically interested in tools, techniques and devices that enable new interaction concepts for the augmentation and empowerment of human abilities. This includes 3D user interfaces, interaction techniques, augmented reality, mixed reality, virtual reality, ubiquitous computing, mobile devices, novel interfaces for medical imaging, multimodal systems, touch-screen interaction, and software/hardware prototyping.

The research projects are from exciting times and inspiring collaborations at different research labs and institutions, including MIT, Columbia University, University of California, KTH (Royal Institute of Technology), and Microsoft Research.I teach at Stanford University and have previously taught at Rhode Island School of Design and KTH.

Expression through Non-verbal Speech
Prosodic features of speech is used together with audio localization to control interactive applications. This information can also be applied to parameter control, or for disambiguation in speech recognition.
