Research Activities

Researcher at INRIA:

As a temporary researcher I have been involved in the SwiTching And tRansmission (STAR) project, developing algorithms to minimise the energy consumed by core networks. We plan to prototype the developed algorithms using FPGAs. My research activities also comprise evaluating the impact of short term reservations for allocating specialised resources in public clouds. I have built a model for the deployment of bare-metal resources in large clusters and data centres. Moreover, I collaborate with colleagues from IBM Research and Samsung Research Institute in Brazil, on auto-scaling for cloud, and the instrumentation of educational environments.

Postdoc at INRIA:

My research focused on improving the energy efficiency of large scale distributed systems such as Grids and Clouds. I investigated the benefits of using virtual machine technologies to consolidate the workload of multi-layer applications, and analysed the characteristics of Cloud computing applications in order to better provision network resources and improve the energy efficiency of Cloud infrastructures. In addition, I was involved in the PrimeEnergyIT project, where I investigated the characteristics and energy efficiency of data storage solutions in order to produce guidelines that can be used by European organisations in procurement of data centre equipment.

During the PhD:

Evidence had shown that most computational Grids worked in isolation, and with different utilisation levels. My thesis presented mechanisms for resource allocation across Grids. The work further evolved into a system to deploy and manage virtual machines across multiple computing sites and commercial Cloud computing providers, and it explored the benefits that organisations can reap from using Cloud providers to augment the capacity of their local clusters.

During the Masters:

Investigated Grid computing and multi-agent systems to improve network and system management. I contributed to the development of a platform whose agents used a prolog-based inference engine to select actions applicable to certain management scenarios given a set of monitoring conditions.

Participation in Research Projects

2014-2015, SwiTching And tRansmission (STAR): In the context of this Chist-era project, I am starting to validade energy-ware routing mechanisms for optical networks.

2010-2011, PrimeEnergyIT: PrimeEnergyIT supported the market development and demand for energy efficient central IT hardware and infrastructure providing tools and services for IT and infrastructure managers, consultants and other relevant experts. It was an initiative operated by an international consortium of national agencies and research institutions in cooperation with a number of associate partners from industry.

2009-2010, Green-Net Project: Provided power aware software frameworks for high performance data transport and computing in large scale distributed systems. It was a cooperative research action supported by INRIA.

2008-2009, InterGrid: Internetworking Islands of Grids: Funded by the Australian Research Council, the project aimed to provide mechanisms for resource sharing among computational Grids.

2004-2005, Advanced Topics in Computer and Telecommunication Networks Management (TAGERE): Funded by the National Council for Scientific and Technological Development (CNPq), I worked on Grids of agents for network and system management.

2002-2003, Hot Topics in Network Management (HOPE): Funded by CNPq, I worked on multi-agent systems for network and systems management.

2000, Student project on pattern recognition: Worked for three months on part of a system to identify the numbers of vehicle registration plates implementing image limiarization techniques using MS Visual C++.
