Research

A former student of Ford Doolittle, Roger's research focuses on the 'deep'
Tree of Life The tree of life is a fundamental archetype in many of the world's mythology, mythological, religion, religious, and philosophy, philosophical traditions. It is closely related to the concept of the sacred tree.Giovino, Mariana (2007). ''The ...

last eukaryotic common ancestor (LECA)
Using phylogenomic approaches Roger's group elucidates the patterns and process of genome evolution in eukaryotic microbes. His research also addresses the evolutionary origin of
mitochondria A mitochondrion () is an organelle found in the cells of most eukaryotes, such as animals, plants and fungi. Mitochondria have a double membrane structure and use aerobic respiration to generate adenosine triphosphate (ATP), which is us ...

mitosome A mitosome (also called a ''crypton'' in early literature) is a mitochondrion-related organelle (MRO) found in a variety of parasitic unicellular eukaryotes, such as members of the supergroup Excavata. The mitosome was first discovered in 1999 in ...
