GESSI, Research in Software Engineering

The research group GESSI has, nowadays, more than twenty people working and it also has around ten PhD Thesis up and running. It is a one and close to the industry needs. The procurement and implementation of COTS components, requirements engineering and software as a service are some of interests of the group. Their research is fundamental for application.

Ull GESSI works in several fields related to Software Engineering. The general framework is based software engineering with recyclable components where the component concept can be very varied: commercial packets (COTS), free software (OSS), services, etc. Around this central issue many work lines arise:

  • Procurement and implementation of OTS components. Nowadays information systems are built mostly, with already existing pieces of software. This seems easy but it is not just a matter of taking the separate pieces and putting them together. In fact, it needs learning how to know which components to adapt and how to introduce the necessary adaptations and modifications so that these pieces of software work together well. "Glue codes" are necessary too.
  • Requirements Engineering. They also work on the processes of software development as well as in process modelling and in the creation of internal software structures in huge blocks.
  • Other subjects: Software process modelling and enactment and particular types of components and packages. ERP and container libraries, for example. They also work in some domains with potential societal and everyday impact like e-learning systems or software for mobile devices.
The group is moving on to research about software services.  Having in mind that software is becoming a basic need even for the most minute aspects and tools of day to day life, this seems to be a very interesting and challenging field of research.

The group has several PhD students presently preparing their theses. They have quite a diverse background which is also reflected in their geographical origins. Many of them come from the other shores of the Atlantic Ocean.

Birrets
Marc Alier, Carlos Cares, Cristina Carreón, M. José Casany, Roger Clotet, Gemma Grau, Lidia López, Oscar Méndez and Freddy Navarrete are some of the current PhD students in the group.

GESSI is currently addressed towards establishing strong technology transfer contracts with companies. The people at GESSI think that working in cooperation with industry in a real context is an enriching experience and it could bring the much needed economic support for their research.

GESSI has also the intention to become a stable research group at the front line in their field with the ability to initiate and manage big projects. Their hope is to see how pieces of software that have been developed in small scale environments, do improve and can reach a wider audience and widespread usage.

The leader of the GESSI research group is Dr. Xavier Franch. He is a person that devoted himself to research since his first years at the university. He and Dr. Pere Botella have been the leader of the group since the very first moment that the group becomes into existence.

Dr. Franch got his degree in Computing Science at UPC. It was a time when students had to change classrooms going from one provisional prefabricated hut to another and treading through barren fields (see Pere Botella's, interview in this same newsletter about those pioneering years of the Barcelona Computing School). Sometimes it seemed sheer madness to have chosen such a fledgling School!.

In those years almost nobody had a clear idea in Spain of what Computing was about and not much people ventured into studying computer science here.  However, everyone was talking about it and it had the promise of a great revolution.

Xavier Franch and some fellow students, among them current associate professor Xavier Burgués and two or three more colleagues, decided to start a collaboration with professor Pere Botella when they where in their third undergraduate year. This resulted in the first of many research papers to follow.

As soon as he graduated, Dr. Franch started as a professor.

LlibreProbably that first research paper and the satisfaction he obtained from his teaching duties and Dr. Fernando Orejas, pushed him towards the continuation of PhD, again under the supervision of Dr. Pere Botella. Franch worked on topics related to the integration of software previously created by different people.  It resulted in his PhD Thesis "Automatic selection of implementations for software components using a multiparadigm language to establish their non functional aspects". This is a topic which is still alive as a research line.

Curiously enough, his decision to pursue this topic for his PhD thesis stemmed from his teaching experience. Before writing his PhD thesis, Xavier Franch had authored a textbook on Data Structures. While writing it he realised that there were many gaps that needed a good deal of research to be filled.

He presently is still very interested in research about the creation of effective high-quality software. He also tries to promote the mobility of researchers as well as international cooperation. His main effort right now is to succeed in establishing a consolidated research group where all members of this research family feel at ease, motivated and with the urge to find new things.

Dr. Franch feels a particular curiosity about the different approaches to computing that different places in the world take.

MonblauHe talks about how computing in the USA and in Europe are completely different. Even within our own continent one can find countries, like Germany or the UK, where the cooperation of research groups in computing and companies is much deeper and more widespread than in Spain. He laments the described current situation since he deeply feels that this type of cooperation is very good and brings in knowledge about real problems.  In fields as oriented towards practical matters as Software Engineering, this is fundamental.

Probably Dr. Franch interest in working with foreign researchers may explain why he has devoted the last two years to make the organization of the 16th IEEE International Requirement Engineering Conference (RE'08) a reality. It will take place from September 8th to 12th, its organization a demanding experience for all members of the group, although quite an enriching one.

Carme Quer, another member of GESSI, is busy also organizing WER'08 a more locally oriented event about Requirements Engineering that will take place on September 12th, 2008.
