Giacomo Bernardi is a Professor of Ecology and Evolutionary Biology at University of California Santa Cruz.
[2] His research includes working on phylogeography, speciation and molecular ecology of fishes, particularly in fishes lacking a pelagic larval phase, Gulf of California and Pacific disjunct species, and in surfperches (Embiotocidae).
He is also interested in population structure of coastal and island groupers.
He also investigates 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.
He studies at the Richard Gump South Pacific Research Station.
