- Activation of small molecules with biological, pharmacological, environmental or industrial interest or related ones [e.g., alkanes (functionalization under mild conditions), alkynes, phosphaalkynes, isocyanides, carbon monoxide, dinitrogen, nitriles, cyanamides, nitric oxide, oximes, oxadiazolines, carboxamides, amidines, olefins, azides or cyanates] by transition metal centres, and developing their application in metal-mediated synthesis and catalysis, namely by searching for mimetic systems of biological processes (e.g. catalysed by peroxidases, particulate methanemonooxygenase, nitrile hydratases and nitrogenases), alternatives for industrial processes and new types of molecular activation with significance in fine chemistry (including the synthesis of compounds with bioactivity). Also comprehending: crystal engineering of coordination compounds, self-assembly of polynuclear and supramolecular structures, transition metal and organometallic chemistries and catalysis in aqueous media, and high pressure gas reactions and catalysis
- Molecular Electrochemistry of coordination and organic compounds, namely towards applications in electrosynthesis, electrocatalysis and in mechanistic studies, as well as in the establishment of potential-structure relationships, and in the induction of chemical reactivity by electron-transfer
- Theoretical calculations for the interpretation of properties and reactivity, at the molecular level
- For the purpose, various techniques and methods (with the acquisition of the corresponding required instrumentation) have been brought in the research Centre by himself and his group, namely for: a) catalysis under unconventional conditions, such as, metal-free, solvent-free, microwave assisted, or in supercritical fluid; b) high pressure gas reactions and catalysis (since 1999, with the cooperation of Prof. A. Palavra); c) conventional molecular electrochemistry (since 1980, e.g. cyclic voltammetry, controlled potential electrolysis and, more recently, electrocatalysis); d) unconventional molecular electrochemistry (since 1990, including the use of ultramicroelectrodes in fast voltammetry, the development and use of digital simulation methods in cyclic voltammetry and their application to mechanistic studies of electrode processes involving fast reactions induced by electron-transfer, in electrocatalysis, etc.); e) stopped-flow spectrophotometry (since 1990, applied to the kinetic investigation of fast reactions, e.g. protonations, in Coordination Chemistry); f) mass spectrometry (including fast atom bombardment, FAB-MS) and its coupling to gas-chromatography (GC-MS) (since 1990, applied to the identification of compounds, e.g. reaction products, and to the induction and monitoring of reactions in FAB conditions); g) thermogravimetry (since 2009); h) microwave promoted synthesis (since 2001); i) catalysis in supercritical fluid (since 2007, with the cooperation of Prof. A. Palavra)

Full Professor at the Instituto Superior Técnico, Universidade de Lisboa, President of the Centro de Química Estrutural and Coordinator of its Synthesis and Catalysis thematic line, Director of the Catalysis and Sustainability (CATSUS) PhD program, Full Member of the Academy of Sciences of Lisbon (in charge of various directive and representative positions) and former President of the Portuguese Electrochemical Society. His research group investigates the activation of small molecules with industrial, environmental or biological significance, including metal-mediated synthesis and catalysis (e.g., functionalization of alkanes under mild conditions), crystal engineering of coordination compounds, design and self-assembly of polynuclear and supramolecular structures, molecular electrochemistry and theoretical studies. He was Chairman of the 25th ICOMC and member of organizing/scientific committees of 40 international conferences or schools. He authored one book (plus four as editor), (co-)authored over 750 research publications, 40 patents, and presented 100 invited lectures at international conferences. His work has received over 17,000 citations, h-index = 59 (Web of Science, Out 2017). Among his honors, he was awarded the following prizes: the Portuguese Electrochemical Society (2015); Madinabeitia-Lourenço (International Hispano-Portuguese) Prize (Royal Spanish Chem.Soc., 2013); Ferreira da Silva Prize (Port.Chem.Soc., 2012); Stimulus for Excellence (FCT, 2005); Scientific Prize Techn. Univ. Lisbon (1st edition; the highest ranked researcher within chemical, biological and materials sciences,based on productivity and impact factor criteria), 2007.
