Timeline

  1. 1993

    A PhD on explicit negation

    At Universidade NOVA de Lisboa, he completes a PhD in Computer Science in October 1993, with a thesis on the semantics of logic programs with explicit negation. His AI research includes logic programming, nonmonotonic reasoning and knowledge representation.

  2. 1993–2000

    Academic posts at Évora

    From October 1993 until he becomes an Associate Professor at NOVA in 2000, he serves as an Assistant Professor in Évora's Department of Mathematics. From 1995 to 1997, he directs the Departmental Area of Exact Sciences. He also heads the Mathematics Department and is responsible in Évora for a joint M.Sc. in Applied Artificial Intelligence with NOVA.

  3. September 2009–September 2011

    Head of Computer Science

    From September 2009 to September 2011, he leads the Computer Science Department at FCT NOVA.

    CDF-Rules for hybrid knowledge bases

    In 2010, he coauthors “Implementing Query Answering for Hybrid MKNF Knowledge Bases” with Ana Sofia Gomes and Terrance Swift. The paper describes CDF-Rules, a query-driven system for hybrid knowledge bases that combines nonmonotonic rules under well-founded semantics with an ontology.

  5. September 2011–June 2018

    Vice-Dean at FCT NOVA

From the biography.

  1. More people shaping AI studied at Massachusetts Institute of Technology than at any other institutionIncludes NOVA University Lisbon. We estimate where the people shaping AI studied and where their careers led. Massachusetts Institute of Technology leads with 467 former students, including 291 recorded doctorates.
  2. The company share of AI researchers’ top papers was 31% in 2020–2024 and 8% in 1970–1974Includes NOVA University Lisbon. We estimate where the people shaping AI worked when their most-cited papers appeared: the company share was 31% in 2020–2024 and 8% in 1970–1974, and Google led all organizations in 2020–2024.
  3. Google had the most people shaping AI every year from 2014 to 2025Our estimates of which organizations employed the most people shaping AI each year from 1955 to 2025, tracing the shift from university labs to companies.
  4. The United States employs an estimated 48% of people shaping AIWe estimate where the people shaping AI work today, how universities, companies and research institutes split across countries, and how country shares have changed since the 1960s.
