Luis Montalvo - Researcher - Technicolor Rennes R&I

Luis Montalvo




Short Bio:

I am a researcher at the Technicolor Research & Innovation center in Rennes-France. I received a  B.Eng. degree in Electronics and Telecommunications from the National Polytechnic Institute (EPN) of Quito-Ecuador in 1982, a M.Sc. degree in Computer Engineering from Ohio University of Athens-Ohio in 1986, and a Ph.D. degree in Microelectronics from the National Polytechnic Institute of Grenoble-France (INPG) in 1995.

From 1980 to 1992, I was a Professor with the National Polytechnic Institute (EPN) in Quito-Ecuador. Between 1995 and 1996, I was a postdoctoral researcher with the University of Minnesota in Minneapolis. Between 1996 and 1997, I was a Research & Development Engineer with ICT Electronics (currently Trend Communications) in Barcelona-Spain. And between 1997 and 1998, I was a postdoctoral researcher with the “Centre National d’Etudes des Télécommunications” of France Telecom in Grenoble-France.

In 1998, I joined Newbridge Networks in Rennes-France. Alcatel acquired Newbridge in 2000 and Thomson Multimedia acquired the CPE xDSL business from Alcatel in 2001. This is the way how I joined Technicolor R&I (previously Thomson Multimedia) where I have been involved in FPGA, board and systems design for gateways, displays, IPTV studios, and cloud storage systems. I am an IEEE and an ACM member.

Research interests:

At present, I am interested in theoretical as well as implementation topics related to MultiPath TCP. MPTCP is an extension of TCP that enables an application to simultaneously use multiple paths for the transmission of data of a single TCP connection between two hosts. MPTCP lets improve the throughput, the resilience, and the resource utilization of the network.

In the past, I worked on the VLSI implementation of efficient computer arithmetic and digital signal processing algorithms using redundant number representations.
