Biography

Jaime Llorca grew up in Barcelona, Spain, where he obtained a B.E. degree in Electrical Engineering from the Universidad Politecnica de Catalunya in June 2001. He then earned M.S. and Ph.D. degrees in Electrical and Computer Engineering from the University of Maryland, College Park, Maryland in August 2003 and August 2008, respectively. He held a post-doctoral position at the Center for Networking of Infrastructure Sensors (CNIS), College Park, Maryland, from 2008 to 2010. He joined Bell Labs at Holmdel, New Jersey, in October 2010, where he is currently a communication networks research scientist.

Jaime's current research efforts focus on understanding the fundamental efficiency limits of cloud-integrated networks and their practical implications for the efficient delivery of next generation augmented information services. He is particularly interested in leveraging concepts and tools from distributed cloud networking, cooperative communications, and network information theory to enable the efficient and sustainable transformation of today's networks and clouds into tomorrow's universal compute platforms.
