• I work in the evolutionary ecology of plant-animal interactions in the Chilean Mediterranean ecosystem. More specifically, I study the complexity of the natural selection process acting upon plant and animal phenotypes in a coevolutionary framework. I focus on mutualistic (pollination, seed dispersal) and antagonistic (parasitism, flower herbivory) interactions. 
  • An additional interest is history and philosophy of science. Currently, I am pursuing a Master degree in Philosophy, with emphasis in abduction, an inference process involved in the first steps of scientific discovery.
