Juan Mr Parrondo

Juan Manuel Rodríguez Parrondo (born 9 January 1964) is a Spanish physicist. He is mostly popular for the invention of the Parrondo's paradox and his contributions in the thermodynamical study of information.

Juan Parrondo received his bachelors degree at 1987 and defended his Ph.D in Complutense University of Madrid at 1992. He started a permanent position at UCM at 1996. At the same year he invented the well-known Parrondo's Paradox, according to which 2 losing strategies may win while working together. Since than the paradox has been widely used in biology and finances. He has also completed a lot of research in the field of Information Theory, mostly looking at information as a thermodynamic concept, which as a result of ergodicity breaking changed the entropy of the system.
