Short BioI am currently Senior Product Manager at ThousandEyes (part of Cisco). I am also an external collaborator at the Broadband Communications Research Group (CBA) from UPC BarcelonaTech, where I obtained my Ph.D. in Computer Science about network traffic analysis and classification using Deep Packet Inspection and Machine Learning techniques. | ||
