My area of research in mathematics is algebraic geometry. Algebraic geometers study zero loci of systems of polynomials by looking at the interplay between the algebraic properties of the systems and the geometry of their solution set. These loci are called algebraic varieties. My focus is in the case when these varieties — and more general constructions called schemes — fall naturally into families that are themselves parametrized by other schemes — or stacks — called moduli or parameter spaces.  Tropical geometry is at the interface between algebraic geometry, combinatorial optimization, and matroid theory. It has become a field of its own, and it is remarkable the broad number of its connections with other areas, such as computational biology or statistics. It has become a powerful tool as well within mathematics, especially in enumerative geometry, providing a bridge between symplectic geometry (which is the natural category in which to discuss Gromov-Witten invariants) and complex geometry. More recently, I have started to study its connections with problems in economics.

Carlos Pereira dos Santos has undergraduate, MSc and PhD degrees in mathematics from the University of Lisbon and he is currently researcher of the Center for Mathematics and Applications (NovaMath), FCT NOVA and professor at ISCTE – University Institute of Lisbon.He researches in the field of Combinatorial Game Theory, stresses the PhD under the guidance of Richard Nowakowski from Dalhousie University, world's top expert on that topic. He published several papers in international journals and presented at major conferences devoted to the subject.About popularization of mathematics, he published the book «Mathematics from The Da Vinci Code», co-authored with Luis Tirapicos and Nuno Crato, he participated in the projects «Games with History» and «Games from Around the World» (Visão/Público) with João Pedro Neto and Jorge Nuno Silva. For 10 years, he was Vice-President of the Ludus Association, one of the most relevant Portuguese institutions dedicated to recreational mathematics. He has been member of scientific committees of pioneering projects such as the «Portuguese Championship of Mathematical Games» and the «Recreational Mathematics Colloquia». He was managing editor of the Recreational Mathematics Magazine.About Mathematics Education in Portugal, he teaches and researches subjects related to elementary mathematics. Also noteworthy is the fact that, for three years, he has made the management of the Training Centre for Teachers of the Portuguese Mathematics Society and, after, he was the director of the Training Centre for Teachers of the Ludus Association. He organized and developed dozens of courses on various topics.

João Madeira is an Associate Professor at ISCTE-IUL. He obtained his PhD in 2008 at Boston University and worked afterwards at the University of Exeter and the University of York. He is a macroeconomist whose research focuses on the sources of business cycle fluctuations and in particular the role played by labour market rigidities. He currently works on understanding better inflation expectations and how disagreement in monetary policy committees arises and impacts the economy.
