Helder Coelho is a full professor of the University of Lisbon (UL) in the Department of Informatics of the Faculty of Sciences, from August 1995. He is permanent and elected  member of the National Academy of Engineering (1999). ECCAI fellow (2002).

 

He graduated in Electrical Engineering at the Lisbon Institute of Technology of the Technical University of Lisbon (UTL) in 1968, obtained a degree of Informatics Expert at LNEC in 1980, his Ph.D. in Artificial Intelligence (AI) at the University of Edinburgh in 1980 and the doctoral equivalence in Informatics Engineering in 1981 from the New University of Lisbon (UNL). He also got the degree of Aggregation in Mathematics from UTL in 1988.

 

His research career started at INETI (ex-LFEN), the National Laboratory for Nuclear Physics in 1968, and in 1973 he moved to the National Laboratory for Civil Engineering (LNEC). He was attached as a scientist to the National Laboratory for Civil Engineering (LNEC) for 16 years, where he co-founded the portuguese AI in 1973. He was involved with the Logic Programming project and he became his leader in 1978. He was coordinator of several PIDDAC projects at LNEC, namely "Information Technologies for Administrative Systems" and "Intelligent Buildings", two JNICT projects on intelligent buildings (one with INESC). He was active participant in SPRINT project RA41 "Expert Systems for Building Services". During this period his main interests were connected to natural language understanding and knowledge engineering within the logic programming paradigm. He was invited as associated professor in 1985 to join and found the Department of Mathematics of the Faculty of Economics and Management (ISEG) of the UTL and he became responsible for the disciplines of Computing Sciences at the Master course of Applied Mathematics to Economics ans Management. In 1990 he became full professor at ISEG and later on he created the Division of Information Technology and Sciences. In 1988, he was responsible for lauching a movement around Distributed Artificial Intelligence in Europe by chairing a panel on the subject at ECAI-88 in Munich. Presently, he chairs the disciplines of Artificial Intelligence in the undergraduate and pos-graduate courses at the University of Lisbon, and he was the head of Informatics Department of the Faculty of Sciences from October 1995 till September 1997. Afterwards he became Director of the Center of the Sciences of Complexity (C3) of the Faculty of Sciences (Lisbon University). He is now scientific coordinator of the LABMAC (Laboratory of Models ans Computational Architectures) of C3.

 

He started working at INESC as the leader of the AI project in 1990, and he was the leader of a JNICT R&D project on DAI, and several joint projects with the software industry. Till October 1995 he was involved with projects connected with administrative systems, such as NORMLOG, supported by Portuguese-American Foundation, and JNICT DEONTLOG and STRIDE JURAD. He was one of the experts (AI/ES PAG) of EUROPACE program, advisor of the board of the Informatics Institute (Public Administration), and reviewer of several ESPRIT projects for ECC. Now he is coordinator of one  center of excelence in the european Compulog network and he is also involved with ESPRITIII network MODELAGE. He is a member of Praxis projects INTERAGE and MAGO, and he is involved with international cooperation with the following AI groups: Birmingham University (United Kingdom), CNR Istituto de Psicologia in Rome (Italy), Madrid Universidade Nacional de Ensino à Distancia (Spain), Institut Leibniz from IMAG/CNRS (France), Lamsade of Université Paris Dauphine (France), Escola Politécnica da Universidade Estadual de São Paulo (Brazil) and Universidade Federal do Rio Grande do Sul (Brazil).

 

He was one of the proponents of the Center of Complexity Sciences of the Universidade de Lisboa, in July 1995, a joint effort of professors of the Faculty of Sciences, Medicine, and Letters from University of Lisbon, in order to build up a multidisciplinary spirit around the current problems of today world.

 

He published more than 25 books, namely Information Technologies (Publicações D. Quixote, 1986), Prolog by Example, How to learn, to teach and use it  (Springer-Verlag, 1988, in English), and in Portuguese Artificial Intelligence (Editorial Caminho, 1991), Artificial Intelligence in 25 Lessons (Fundação Calouste Gulbenkian, 1995) and Dream and Reason, on the side of the Artificial (Círculo dos Leitores, 1996), and more than 400 papers.
