Sergio Munoz, Ph.D Student


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) diveristy 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 Septemeber 2015, I also joined the laboratory of Dr. Andrew Roger. Under their co-supervision, I am currently investigating the origin and early evolution of mitochondria and their internal structure.

Research interests:

My general interests encompass the evolution of the cell, the origin and diversification of eukaryotes, and endosymbiosis. My main Ph.D. project addresses the origin and early evolution of mitochondrial ultrastructure, as well as the nature of the alphaproteobacterial ancestor of mitochondria. 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 on the evolutionary and developmental dynamics of endosymbiosis, and the evolution of mitochondria and eukaryotes.
