  • Since September 2007 I lectured Multimedia and Information Systems and Artificial Intelligence to Computer Science Students at Universidade Lusófona.
  • From February to August 2004 I took a sabbatical leave at the “Modeling Algorithms and Information Group, CCS-3”, Los Alamos National Laboratory, USA to work on complex systems.
  • From October 1998 to July 2000, Professor of Physics at the Lusófona University where I tough physics to 3th year computer science undergraduates. I was also a postdoc at the Instituto Tecnológico e Nuclear in Sacavém, Portugal, working on Monte Carlo simulations for the transport of neutrons and photons on the Portuguese Nuclear Reactor.
  • From July 1997 to June 1998, postdoc on fission of highly charged clusters with Dr. Claude Guet, head of the Service des Ions Atomes et Agregats, of the Comissariat de l`Energie Atomique (CEA), Grenoble, France.
  • From September 1993 to June 1997, I worked in the Physics Department of the University of Coimbra as a PhD student. My thesis was on fission of metallic clusters using a semi-classical theory and atomistic models based on Density Functional Theory.
  • From 1990 to 1993, master student in the Center of Nuclear Fusion, in the Technical University of Lisbon.  In this work I studied the Magnetohydrodynamics equilibrium of the plasma of the Portuguese nuclear fusion reactor.


Scientific activity & major achievements:

  • Recently I start working on Complex Network analysis and its applications to recommendation systems and information spreading in social networks, namely scale free weighted networks and fuzzy graphs.
  • Since 2003 I have been working on innovative machine learning algorithms for neural networks and genetic algorithms, especially in processing with high-dimensional data: Multidimensional Scaling (MDS); Isomap mapping, Non-negative Matrix Factorization (NMF). These algorithms were applied to bankruptcy prediction, data filtering protein folding, and web personalization.
  • In collaboration with Carvalho das Neves, we developed a new algorithm to train Neural Networks for classification problems and its application to complex tasks, namely financial distress prediction of private French companies – beta version of project AIRES at aires-risk.com
  • With Gaspar Cunha we developed a method to accelerate the search of the Pareto-front in Multi-Objective Evolutionary Genetic Algorithms with Neural Networks.
  • Together with Nuno Barradas we have developed a fully automated Rutherford Backscattering data analysis capable to adjust all experimental parameters in order to obtain the best possible spectra for a specific sample to be analyzed.
  • From 1998 to 2000 I worked for the Portuguese Research Nuclear Reactor on the problem of neutron transport using Monte Carlo Simulations. One of the projects were the study of reliability of electric circuits when subjected to intense flux of fast neutrons
  • From 1993 to 1998 I worked on fission of charged metallic clusters using a semi-classical formalism.
  • From 1990 to 1993 I worked on physics of tokamaks (controlled thermonuclear fusion devices) in characterizing the equilibrium state of the hot plasma using measurements of the magnetic field at the exterior of the chamber.

  • My researh

    After my PhD at University of Coimbra, I spend a year in Grenoble, France, as a Postdoc. Then I decided to do something new.
    From 1998 to 2000 I worked on the <a href=”http://www.itn.pt/”>Portuguese Nuclear Reactor</a> at Sacavém, studying neutron diffusion and radiation protection.

    Since 1998 I fell in love with <a href=”http://en.wikipedia.org/wiki/Neural_network”>Artificial Neural Networks</a> (ANN) and Machine Learning. I applied these techniques to any problems that I could put my hands on: from physics to economics or even deep oil discovery. We were able to successful apply ANN to several Rutherfod  BackScattering (RBS) spectra analysis of thin films and revolutionize the field of real-time RBS.

    In 2003, I was able to propose a new algorithm to train Neural Networks for classification problems and apply it to complex tasks, namely financial distress prediction of private French companies.

    In 2004 I took a Sabbatical leave at <a href=”http://www.lanl.org/”>Los Alamos National Laboratory</a> to engage in the study of Complex Network Analysis.  A topic that I eventually resume early in 2011 and in which I have a keen interest, especially in its applications to recommendation systems and correlated credit events (dominó bankruptcies). Early 2011 Tiago and I were the first portuguese team to be accepted at Seedcamp London, the biggest entrepreneurship meeting in Europe.

  • My Passions

    Data analysis, algorithms, machine learning, social networks, complexity.

  • My Education

    I had the privilege to take my degree of Physics, in 1990, at one of the best Portuguese engineering schools, <a href=”http://www.ist.utl.pt/”>Instituto Superior Técnico</a>, in the beautiful city of <a href=”http://en.wikipedia.org/wiki/Lisbon”>Lisbon</a>.
    In 1993 I took the master degree in Plasma Physics to study the hot plasma of the <a href=”http://www.cfn.ist.utl.pt/eng/index.html”>ISTOK</a> tokamak using function parametrization. I moved to Coimbra in 1993 for my PhD in Theoretical Physics. Though I didn’t love the city, I got fascinated by the personality and character of Professor <a href=”http://pt.wikipedia.org/wiki/Carlos_Fiolhais”>Carlos Fiolhais</a>. The thesis was on fission of metallic clusters – building blocks of nanotechnology.

  • Teaching

    Beside being a full professor of physics at ISEP, I lectured on several international post-graduated degrees, like master in Bioinformatics in University Pompeu Fabra in Barcelona and at a MBA on real estate in <a href=”http://iseg.utl.pt/”>ISEG</a>, Lisbon.
