I was born on December 31 in Lisbon, Portugal. Since my father was a career diplomat, I traveled extensively.

I started walking in Nicaragua then moved to France. Later I lived in Brazil followed by Belgrade in the former Yugoslavia where I learned English. Next I went to Sofia in Bulgaria and finally returned to Portugal.

I attended the American International School of Lisbon.

I obtained a bachelor degree in electrical engineering from the University of Connecticut in the USA.

I did my military service in Portugal.

I enrolled as a graduate student at the Instituto Superior Técnico in Lisbon. I completed all course work for the master degree in physics while working as a teaching assistant. I was for a short period a scientific associate at CERN.

I presented a poster abstract entitled, "The distribution of prime numbers hidden within a fractal binary pattern" at the Fractal 2004 conference in Canada.

I attended the NKS summer school which took place at Brown University in the USA. My project concerned the Collatz problem.
