I received my B.Sc. Honors in Biology from Universidad de Antioquia in Colombia. During my undergraduate years I made emphasis on microbial (and algal) diversity and evolution, as well as molecular evolution and phylogenetics. I did my B.Sc. Honors thesis on the evolutionary history of green plants (Viridiplantae) and their plastid genomes. In September 2013, I joined the Center for Comparative Genomics and Evolutionary Bioinformatics (CGEB) under the supervision of Dr. Claudio Slamovits. In September 2015, I also joined the laboratory of Dr. Andrew Roger. Under their co-supervision, I successfully defended my Ph.D. thesis on the evolutionary origin of mitochondria in November 2018. Since then I have started a ‘bridge’ postdoctoral stay in both labs to follow up on Ph.D. research and gain further insights into the ancestor of mitochondria.
My general interests encompass the evolution of the cell, the origin and diversification of eukaryotes, and endosymbiosis. My main Ph.D. project was concerned with the anatomical and genealogical nature of the first mitochondrial ancestor, or the alphaproteobacterium from which mitochondria evolved. My immediate postdoctoral research at the Roger and Slamovits labs will expand on my Ph.D. thesis by also addressing the genomic and metabolic nature of the first mitochondrial ancestor. I am also interested in plants and algae, and the evolution of their plastid organelles. I combine bioinformatics and genomics, as well as experimental biology, to improve our understanding of the evolutionary and developmental dynamics of endosymbiosis, and the origin and evolution of mitochondria and eukaryotes.
