About
Born in the resplendent city of Riobamba and raised in Quito, I lived two decades of my life amongst the amazing Ecuadorian mountainous landscapes. From an early age, I was engrained with understanding the importance of protecting life in all of its forms. Quickly my love for animals, Biology and Ecology grew and eventually led me to Argentina, where I pursued a Bachelor in Genetics.
B.S, M.S & PhD Student.
While pursuing my undergraduate degree at Universidad Nacional de Misiones, I ventured in studying chromosomal features in the elusive Myotis bat genus.
Unsolved questions from this work woke in me a particular interest in Transposable Elements and in their potential to be used as molecular markers to solve intricate phylogenetic relationships in this group.
As part of my Master of Science projects at the Ray Lab, my research on immune response of bats enabled me to infer the evolution of gene families related to antimicrobial peptides in this remarkable group of mammals. Additionally, I laid the groundwork to characterize a specific type of Transposable Element to construct homoplasy-free phylogenies in Chiroptera. Currently, as a PhD student, one of my projects focuses on optimizing this pipeline with the aim of expanding its applicability to other taxa. While my primary research interests revolve around taxonomy, I also explore other adaptive traits that render bats unique among mammals, with metabolism being a key focus.
As a member of the Fundación Oso Andino, my involvement extends beyond Genetics and bat research. I lead projects that seek to study the behavior of large mammals by means of analyzing GPS tracking data. Using novel bioinformatic non-parametric methods, I am looking to understand how Andean bears, Andean foxes and tapirs, make use of their natural habitat and what resources and environmental variables
may have an impact on how they move across their utilization distributions.

Skills
My current bioinformatics projects demand some skills on programming languages, I've listed the ones I use and understand the most. I supplement my coding skills with some knowledge on design software since I enjoy preparing or polishing figures for presentations and/or posters.
Portfolio
This is some of the visual work I have created by merging the results of software for phylogenetic reconstruction as IQ-TREE and Mega, and the R programming language, with Adobe Illustrator and Photoshop. Most of my plots are heavily coded in R with the packages: tidyverse, movevis, rayshader, elevatr, tidyterra, and many many more.
