Research Interests

The diversity of the present human populations from all the points of view: morphologic, biochemical and genetic. For that reason it interests to me to know the factors that condition the biological structure of the human populations and that express themselves through you reproductive pattern.


In accordance with my areas of interest, the different lines of investigation that development they persecute to value:
  • Los changes in the fertility, infantile mortality and survival to the reproductive age, as much on isolated population as even on the Spanish population.
  • La microdifferentiation of populations, on small or great scale, by means of the use of surnames. It represents an approach the genetic analysis.
