Pablo was born in Medellin, Colombia, where he completed his undergraduate studies in biology, majoring in genetics. In 2005, he moved to France and finished a Master's degree in Coastal Oceanography at the Pierre et Marie Curie University. He completed his PhD in a cotutelle program between the Ecole Pratique de Hautes Etudes in France and James Cook University in Australia. In his dissertation, he studied population connectivity of a clownfish species (Amphiprion polymnus) in Papua New Guinea using genetic parentage analysis. 

Pablo joined the Reef Ecology lab from fall 2011 until summer of 2014, and his work has targeted two main research themes: 1) developing a comprehensive analysis of genetic assignment methods for estimating population connectivity in marine fishes, highlighting the power of DNA parentage analysis in estimating fine-scale demographic connectivity, and testing different statistical methods to infer larval dispersal in natural marine populations; and 2) describing patterns of larval connectivity for several coral reef fishes, assessing their importance in the resilience and persistence of populations and for the local human communities. Lately, Pablo has been expanding his research to include population genetics and genomics of ecosystem biodiversity using a broad range of coral reef organisms, including sponges, corals, and fish of the Red Sea.

Pablo is currently an Assistant Professor at the Univesidad Austral de Chile.
