Research Interests
Our laboratory research focuses on understanding speciation mechanisms in Marine Organisms. We have elected to specifically work on fishes as model systems. To approach this vast question, we mainly investigate two different fields of Molecular Evolution. 1) Molecular Phylogenetics: We are interested in understanding phylogenetic relationships between species complexes that correspond either to large groups (Scarids) of fishes, or to species that are in the process of speciation (i.e.Girella, Dascyllus). 2) Population genetics: We are generally interested in studying the relationships between dispersal capabilities and gene flow in fish populations. Our main areas of investigation are the temperate and subtropical Eastern Pacific, the Sea of Cortez, and the Indo-West Pacific.
Current ProjectsWorking on phylogeography, speciation and molecular ecology of fishes. Particularly interested in fishes lacking a pelagic larval phase, in Sea of Cortez/Pacific disjunct species, and in surfperches (Embiotocidae). Comparing phylogeographic and gene expression patterns to test for local adaptation in a high gene flow species. Populations structure of coastal and island groupers. Investigating adult population structure and the structure of a new year-class within Sebastes mystinus (blue rockfish) and Sebastes atrovirens (kelp rockfish) over multiple temporal and spatial scales. |
