Introduction
I am a seasoned biologist with expertise in genomics for ecological, evolutionary, and conservation research. Currently, I serve as the Head Entomologist (PI) at NRGene Canada Inc., leading Black Soldier Fly studies that integrate genomics and software development for breeding and data analysis. Additionally, I hold an active lecturer position at the Pontificia Universidad Católica del Ecuador.

Similar to other insular birds around the world, the Galapagos rail (Laterallus spilonota Gould, 1841) exhibits reduced flight capacity following its colonization of the archipelago ~1.2 mya. Despite their short evolutionary history, rails have colonized seven different islands spanning the entire width of the archipelago. Galapagos rails were once...
Background
The Galapagos sea lion, Zalophus wollebaeki, is an endemic and endangered otariid, which is considered as a sentinel species of ecosystem dynamics in the Galapagos archipelago. Mitochondrial DNA is an important tool in phylogenetic and population genetic inference. In this work we use Illumina sequencing to complement the mitogenomic res...
• The young leaves are the main source of nucleic acids for population genetic studies in palm‐trees; however, the access to this tissue may be limited by specific features of each species. Using root tissues as an alternative source of nucleic acids could facilitate the sampling in large populations.
• This study tests root tissue viability as an...
Anthropogenic changes to the environment challenge animal populations to adapt to new conditions and unique threats. While the study of adaptation has focused on genetic variation, epigenetic mechanisms may also be important. DNA methylation is sensitive to environmental stressors, such as parasites and pesticides, which may affect gene expression...

The biotas of the Galápagos Islands are one of the best studied island systems and have provided a broad model for insular species' origins and evolution. Nevertheless, some locally endemic taxa, such as the Galápagos Rail Laterallus spilonota, remain poorly characterized. Owing to its elusive behavior, cryptic plumage, and restricted distribution,...
The biotas of the Galápagos Islands are probably one of the best studied island systems and have provided a broad model of insular species’ origins and evolution. Nevertheless, some Galápagos species remain poorly characterized, such as the Galápagos Rail Laterallus spilonota . This bird species is one of the less explored groups of endemic vertebr...
