Claudio is a molecular ecologist and a marine biogeographer at Universidad de Magallanes, Chile. He is interested in understanding the main biogeographical patterns of the Southern Ocean near-shore marine benthic fauna. He is currently working with several models of marine molluscs using molecular markers at different geographical and temporal scales, trying to further understand the underlying processes related to the current distribution of the Southern Ocean fauna. In particular, Claudio is comparing congeneric populations of different mollusc taxa from different provinces of the region, including Central Chile, Patagonia, the Antarctic Peninsula, and Subantarctic Islands (i.e. Crozet, Kerguelen, Falklands, South Georgia, and Marion). He is the South American representative of the SCAR (Scientific Committee on Antarctic Research) scientific research programme AntEco (State of the Antarctic Ecosystem).

Claudio has been working in Antarctic and Subantarctic research for 10 years. His PhD thesis examined the biogeography of the genus Nacella (Patellogastropoda: Nacellidae), one of the dominant marine invertebrate across the Southern Ocean. Hence, most of Claudio’s work has focussed on a circumpolar geographical scale, with special emphasis on Sub-antarctic oceanic islands (Marion, Corzet, Kerguelen, Heard, Macquarie, and Campbell). He has participated in several campaigns in Antarctic Peninsula, Falkland Islands, Juan Fernández Archipelago, Easter Islands, and especially along southern South America
