Wearable Sensing Team

About Our Team

Wearable Sensing's team draws on skills and expertise of QUASAR's leading research scientists and engineers who provide consulting services to support development of new products and manufacturing processes. In addition, Wearable Sensing's staff includes technicians and sales and support staff.


President: Dr. Walid Soussou leads and manages Wearable Sensing’s efforts at developing markets for its wearable dry-sensor technology. Dr. Soussou leverages his PhD in Neuroscience from the University of Southern California (USC), expertise in Brain-Computer-Interfaces, and experience in sleep research, for developing commercial applications of wearable sensors. Dr. Soussou is VP of Research at QUASAR.

For Wearable Sensing, Walid directs product development, as well as marketing and sales efforts.
