Biography

I am currently senior research engineer at Bell Labs in the Network Algorithms, Protocols and Security program. My research is focused on multimedia delivery, mainly on providing generic network functions and its algorithms and protocols to improve multimedia content delivery and facilitating multimedia application development. I’m interested in transport protocols, as many generic services in the internet architecture are (or could be) located at that layer.

Project contributions:

5GBB: Low latency transport protocols and AQMs
SHIFT-TV: Multi-Screen, -Place and Time-Shifted Digital Television; Transport protocol for adaptive live and on demand streaming
FP7 RITE: Low latency transport protocols and AQMs
FP7 OCEAN: Caching strategies for multimedia delivery
IWT PHANTER: HAS caching with multicast feeds for live streams; Transport protocol for streaming
FP7 ECODE: Machine learning for transport layer accountability
CELTIC RUBENS: Scalable application agnostic transport protocol for multimedia delivery; PCN for VBR video delivery
