Fernando Brito e Abreu is the leader of QUASAR and, as such, conceives the overall strategy for this research group. He proposed the MOOD and MOOD2 metrics sets and the GOODLY design language. He conceived an approach to reengineer the modularity of OO legacy systems based on cluster analysis and produced the MOTTO tool to support it. He also proposed the M2DM (MetaModel-Driven Measurement) approach, in which metrics are formalized with OCL (Object Constraint Language) upon any given metamodel.

Miguel Goulão is a PhD student and is currently working in Component Based Software Engineering, with a focus on software components quality assessment. He was a member of the former MOOD team since its creation in 1994 and has participated in several experiments relating to the empirical validation of Fernando's proposals. He also contributed to the project as a member of the teams that developed MOODKIT 1 and the tool support for metrics formalization. During his MSc, he developed SOFTRACK, a framework for tracking the evolution of legacy systems and providing quantitative data to guide software process improvement.

Aline Lúcia Baroni (MSc)
email: alinebaroni[at]di[dot]fct[dot]unl[dot]pt

Aline Baroni is a PhD student. The main topic of her research is the quantitative evaluation of behavioral modeling, at design phase. She developed her MSc thesis work at QUASAR on the topic of formalization of object-oriented design metrics. She extended the original work of Fernando, by using the UML metamodel instead of the GOODLY one, as a framework to formalize OO design metrics with OCL. The main results were the FLAME (Formal Library for Aiding Metrics Extraction) library, a set of formalized metrics and a measurement framework.

Sérgio is currently working on his MSc thesis dissertation. His dissertation work intends to produce concrete evidence that AOSD (aspect oriented software development) leads to an expressive (measurable) modularity improvement upon OOSD (object oriented software development). To this end, a coupling and cohesion framework was developed and functionally-equivalent systems, implemented with both object and aspect-oriented approaches, are being assessed using the M2DM approach. The results of this work are expected to help IT development managers decide upon this new technology migration.

Luís Silva
email: lsilva[dot]email[at]gmail[dot]com

Luís is a MSc student. His research aims at developing an open framework for performing metamodel-based quantitative studies upon IT Infrastructures, using Microsoft's SDM (System Definition Model) proposal. SDM is a modeling language used to capture a model of a computational system, including all information pertinent to deployment and ongoing operations. The proposed framework is expected to help in activities such as documenting IT infrastructures and their operation, evaluating TCO (Total Cost of Ownership) or comparing infra-structures' complexities.

Jorge Freitas
email: jorge[dot]freitas[at]mail[dot]telepac[dot]pt

Jorge is a MSc student. He is working on his thesis on "Information Technology Service Management Metamodeling". Information Technology Service Management (ITSM) is a term that intends to cover all aspects dealing with the management of IT service provision. In the last decade several reference models for ITSM have been proposed, with a great deal of overlapping, such as: Information Technology Infrastructure Library (ITIL), Information Services Procurement Library (ISPL), Application Services Library (ASL), Dynamic Systems Development Method (DSDM), or Control Objectives for Information and related Technology (COBIT). The objective of this dissertation is to provide a framework to allow comparisons among those reference models. This framework will basically consist of a domain metamodel which can be instantiated with the referred models. Some comparisons based upon that metamodel will then be performed to illustrate its suitability.

Andreia is working on her MSc proposal, which is a solution to integrate the Software Quality Evaluation Process, as defined by the ISO 14598 (Process Quality Evaluation) and ISO 9126 (Product Quality Characteristics), with the Software Process Engineering Metamodel (SPEM) from the Object Management Group (OMG). To this end she is building a profile that extends SPEM with the quality evaluation concepts proposed in ISO 14598 and 9126.

Paula is currently working on his Msc thesis research work. Her main objective is the identification, discussion and validation of abstraction traceability mechanisms in UML2 Meta-Modelling. She is developping a tool called MEMENTO (Meta-Modelling Enlightening Tool), to map UML diagrams at level M1 into UML diagrams at level M2.
