Pedro Martinez Arbizu is a Professor for Marine Biodiversity at University of Oldenburg in Germany and Head of the German Center for Marine Biodiversity Research at Senckenberg Research Institute. He started his copepodologist career at Prof. Schminke's lab studying groundwater copepods from the Iberian Peninsula. For his PhD he studied the phylogenetic relationships of copepod orders with focus on the relationships of marine Cyclopoida to other copepod orders, suggesting that poecilostomes are a derived branch within Cyclopoida. During the past 20 years he focused his research on marine, specifically deep-sea copepods. He has described with several co-workers and students new species of Platycopioida, Calanoida, Misophrioida, Siphonostomatoida, Cyclopoida and Harpacticoida.
