My name is Ron Eytan. My lab studies the origin and maintenance of marine biodiversity, primarily in coral reef fishes, using genomic and computational methods. My lab has broad interests in phylogenomics and phylogeography, population genetics/genomics, and the geography and genetics of speciation in reef fishes.

Research

The focus of my research is the origin and maintenance of marine biodiversity, particularly in coral reef fishes. My Ph.D. dissertation work was on the population genetics and rates of molecular evolution of a group of small Neotropical reef fishes, the tube blenny genus Acanthemblemaria. My postdoctoral work focused on resolving and measuring the Acanthomorph Tree of Life.

At this point, my lab's primary focus is on the group of fishes called blennies. Why blennies? Near et al. (2013) found that blennies are one of the most exceptionally diverse groups of fishes living on reefs. My lab aims to understand this diversity at multiple levels of biological organization, ranging from molecular evolution at the level of the genome, population genetics at regional spatial scales, cryptic speciation and local endemism, to higher level molecular phylogenetics and systematics. We have a holistic approach to our research, combining genomic, computational, and classical genetic methods, with a healthy dose of field work.
