BCAM is looking for up to three postdoctoral fellows with a potential for
high-quality research within the interests of the NET research group (see
below). You will have recently obtained Ph.D. (or be close to its
completion) in a strongly quantitative field such as mathematics, computer
science, operations research, telecommunications engineering, economics or
related. Your research interests will be in stochastics, with interests in
developing and applying mathematical approaches for performance evaluation
and optimization of real-world problems. Preference will be given to
candidates pursueing interdisciplinary research that strengthens and/or
complements the current research of the group.

NET Research line Objective
The main goal of NET consists in the performance analysis, evaluation and
optimization of communication networks such as the Internet, wireless
cellular systems, or other complex interconnected systems. We design
mathematical models to capture the dynamics of fundamental aspects of
real-world systems in order to achieve a better utilization of resources.
For instance, we look for designs that make a balance between energy
consumption and system performance in order to offer a sustainable service
to customers. We aim at understanding the phenomena, developing tractable
mathematical methods, algorithms, and software tools to provide
interpretable and implementable solutions for the industry and for the
society.
Description
The development of complex interconnected systems requires smart and novel
solutions for efficient resource management and their sustainability. The
idea of NET is to offer an interdisciplinary team dealing with resource
allocation problems in systems arising in different industries. The main
techniques we use and develop belong to the intersection of mathematics,
computer science, and economics. Our work is closely linked with the branch
of mathematics known as operations research or management science.
The Internet is today the fundamental component of worldwide communications
infrastructure. In recent years, the use of both the Internet and wireless
services has experienced an explosive growth and has had a striking impact
in the world-wide economy. Network operators and service providers
anticipate further expansion, boosted by the emergence of all-optical
networking as well as the convergence of wireless and Internet access,
along with a fundamental trend towards service integration. It is expected
that future information and communication systems will accommodate a
variety of new applications with a diverse range of Quality-of-Service
(QoS) requirements. These observations have raised the need for the
development and analysis of mathematical models to predict and control the
QoS of information and communication systems, including wired and wireless
networks and large-scale distributed systems.
Our scientific contributions are both theoretical, with the development of
new modeling formalisms, and applied, with the development of algorithms
and software tools. More specifically, the main mathematical tools that are
used and to which we aim to contribute are: theory of stochastic processes
(Markov process, point process, Palm measure and large deviations), theory
of dynamical discrete-event systems (queueing theory, fluid approximations,
mean-field limits) and theory of optimization and control (dynamic
programming, Markov decision process, game theory, deterministic and
stochastic scheduling, relaxation techniques, and path-wise comparison). We
further pursue research on the frontier between mathematics and computer
science, belonging to areas such as statistical learning, probabilistic
algorithms for control under incomplete information, and evolutionary
computation.
An important part of our work are simulations and computational
experiments. Areas of research interests currently range over optimal
scheduling in wireless networks and call centers, energy-efficient
networking, flow-aware congestion control of TCP, network economics,
approximations for resource sharing, perfect simulations, revenue
management, etc.
Applications
The main applications fields of our knowledge and research are typically
within the fields such as telecommunications, electrical engineering,
industrial engineering, business administration and finance.
The main application area is networking and in particular Internet
infrastructure (routing, admission control, congestion control, Voice over
IP, quality of service), Internet applications (content distribution
systems, peer-to-peer systems, cloud computing, data centers) and wireless
cellular networks (scheduling, wireless-LAN, WiMax, UMTS, CDMA 1xEV-DO,
LTE, power control, medium access control, transmission rate control).
We have an ongoing collaboration with industrial partners such as
INGETEAM-TRACTION (on optimal control of trains) and C.D. FORTUNA (on
analysis and optimization of the organization of the Behobia-San Sebastian
marathon).
