Guevara Noubir's area of research:

My research covers both theoretical and practical aspects of communication protocols, wireless communications, network security, fault tolerance, and embedded systems. I have over 50 publications in these areas. I was the PI for a project funded by DRAPER Laboratory on “Secure Location Related Services” [2002-2004]. I am also recipient of the NSF CAREER award on "Cross-Layer Protocols for Robust and Scalable Heterogeneous Wireless Networks" [2005-2010].

From 1997 to 2000, I was a senior research scientist at the Real-Time Software and Networking Group at CSEM SA (Switzerland), and I led several research projects in the area of wireless systems and secure networking. I contributed to several European projects as work-package leader, task leader or active member of workpackages. Examples are the Multimedia Access and Distribution European ESPRIT project, where I led the task of specifying, simulating, and implementing in SDL the ETSI-Hiperlan 2 wireless LAN ensuring multiple QoS wireless connections. I led the network security workpackage of JAMES European project. I contributed to the definition of the third generation Universal Mobile Telecommunication System (UMTS-WCDMA) through my active participation in the FRAMES European project both on the system side and demonstrator side. The FRAMES project led to the European proposal 3GPP at IMT2000 for a third generation mobile communication system. More specifically, I investigated the critical problem of radio resource management and developed several algorithms for the deployment and optimization of Hierarchical Cells Structures. I also participated to the development of one of the first 3G-UMTS demonstrators by leading the specification and implementation task of the data packet communication of the FRAMES demonstrator. I participated in several projects for building low-cost spread-spectrum communication devices for the European Space Agency and for the Swiss industry. I also actively worked on the optimization of Internet protocols (i.e., IP, TCP, IPsec) for satellite links.

Prior to joining CSEM, I earned my Ph.D. (Advisor Prof. Henri Nussbaumer IEEE & IBM Fellow) at the Swiss Federal Institute of Technology in Lausanne (EPFL) on the design of fault-tolerant communication protocols (using signature analysis and algebraic coding techniques). In my Ph.D. thesis I demonstrated that algebraic techniques using coding, polynomials, and signatures analysis significantly improve the reliability of communication protocols.
