Estuary Ecology and Evolution

Phylogeography: Evolution of estuarine taxa and underlying geologic mechanisms.
Geology plays an important role in shaping the evolution of organisms. Baja California, Mexico is a hotspot for endemism and provides a prime opportunity to study this interplay. Much of our work focuses on understanding historical events by which fishes migrated between the Pacific and Gulf of California and how this impacted subsequent evolution. Using cutting edge sequencing technology, we’re testing potential genes under differential selection, and affects of habitat and historical processes on diversity and rates of molecular evolution.

Evolutionary Development (Evo Devo): Nervous and sensory structures of jellyfish
Jellyfish are members of the Cnidaria, a phylum that is the sister group to 99% of all animals alive today. Despite their deep ancestry with more complex animals, jellyfish share many homologous genes. We are focusing on genes that are deployed in the development of nervous and sensory systems in other animals, to see if they are used in a conserved manner in the jellyfish Aurelia sp.1
