Research interests

My research has been focused mostly on the study of genetic variation in natural populations of amphibians and reptiles. However, I’m interested in almost any aspect of biology involving speciation evolution at several ecological and taxonomical scales. Currently, I’m dedicated to the study of two different models:

  1. Evolutionary and ecological changes in microbial communities of agriculturally important mites.
  2. Morphological, genetic, and ecological variation in worm lizards of Puerto Rico (genus Amphisbaena).
