obeloOrlando Belo
is an Associate Professor, with Habilitation, in the Department of Informatics at University of Minho, Portugal.

He is also a member of the ALGORITMI R&D Centre, at the same university, working in Business Intelligence, with particular emphasis in areas such as Databases, Data Warehousing Systems, OLAP, Data Visualization, and Data Mining.

During the last few years he was involved with several projects in the decision support systems area designing and implementing computational platforms for specific applications, such as fraud detection and control in telecommunication systems, data quality evaluation, and ETL systems for industrial data warehousing systems.

Jácome Cunha
 is currently an Assistant Professor at Universidade NOVA de Lisboa, Department of Informatics, and an integrated member of the research center NOVA LINCS.

His research is mainly focused on Programming Languages (PLs) and Software Engineering (SE), where he try to improve the effectiveness, efficiency, and usability of software. He have contributed with such techniques for spreadsheets, and for improving software energy consumption.

He obtained my PhD degree in Computer Science from Universidade do Minho in 2011. He was then a post-doctoral fellow at Universidade do Minho and Oregon State University. He was also an Invited Professor at Escola Superior de Tecnologia e Gestão de Felgueiras – Instituto Politécnico do Porto.

Between September 2002 and February 2003, Rui followed courses of the Software Technology Master Course at University of Utrecht, the Netherlands, as an Erasmus Exchage Student. He was an intern researcher at Philips Research Labs, the Netherlands, between October 2004 and June 2005.

He received his Ph.D. degree from the Delft University of Technology, the Netherlands, in November 2009, and he is currently an assistant professor at the Faculty of Engineering of University of Porto, Portugal.

 Rui Pereira is Computer Science PhD student at the University of Minho, under the MAPi doctoral programme. He received his MSc degree in Software Engineering and Business Intelligence in 2013, with his thesis “Querying for Model-Driven Spreadsheets” under the SpreadSheets as a Programming Paradigm (SSaaPP) project. He continued working on his MSc work, extending it further into other approaches, along with working on spreadsheet model quality, human-computer interaction, and software analysis and transformation.

For his PhD, he is working on reducing the energy consumption levels for software, by using source code analysis, transformation, and manipulation techniques.

Rui Pereira’s current research interests are software engineering, green-computing, source code analysis and manipulation, and human-computer interaction.

Marco Couto completed is MsC degree in Informatics Engineering in 2014, with a thesis entitled “Monitoring Energy Consumption in Android Applications”, with a scholarship in a project called GreenSSCM – Green Software for Space Control Missions, at the University of Minho.

 He is currently a PhD student in the MAP-i doctoral program. He is still working on the energy-aware software/green computing area, since his PhD thesis theme is “Energy-aware Software Product Lines”.

Miguel Guimarães completed his MsC degree in Informatics Engineering in 2014 and specialized in Business Intelligence and Software Engineering, with the thesis entitled “Generation of Skeletons for ETL System based on Coloured Petri Nets”. He is a PhD student at the University of Minho under the PDInf doctoral programme. Miguel joined the Green Software Lab in 2015 and is currently researching techniques and methodologies to reduce the energy consumption on Database Management Systems and Data Warehouse Systems.
