Dr. Andres Garcia-Saavedra

Principal Research Scientist

Andres Garcia-Saavedra is a Principal Research Scientist at NEC Laboratories Europe, Germany. His research interests lie in the application of fundamental mathematics to real-life computer communications systems, both wired and (especially) wireless; including resource allocation problems, energy efficiency, low-delay communications, Tactile Internet applications (haptic VR/AR) and virtualized radio access networks. He particularly enjoys building real prototypes and carrying out experimental performance evaluations of protocols and communication systems.
