Leyla Cárdenas Tavie
Professor at the Environmental and Evolutionary Science Institute from the Faculty of Science at the University Austral of Chile.
Marine Biologist from the University Austral of Chile and PhD in Biological Sciences with a Major in Ecology of the Pontifical Catholic University of Chile. Her main area of research, are processes of dispersion, isolation and historical and contemporary extinction of marine species through population genetics. She currently leads the research project “DNA barcoding as a tool to describe the biodiversity of parasites in marine invertebrates” funded by the Chilean Antarctic Institute (INACH) and is co-investigator of a Fondecyt project to understand the evolution model in marine parasites.

Professor at the Environmental and Evolutionary Science Institute from the Faculty of Science at the University Austral of Chile. PhD in Biological Sciences at the University of Paris XIII, France.
She is a specialist in algae population genetics. Throughout her career, she has studied the processes that cause changes to biodiversity, especially in the coastal sea area. Her research has been focused on understanding natural and anthropogenic processes that affect the permanence of macroalgae populations.

Claudio González Webar
Marine Biologist and Master of Science, mention in Genetics, from the Universidad Austral de Chile. Dr. González completed his PhD in Biological Sciences with a major in Ecology and Evolutionary Biology at the Universidad de Chile.
Over the past decade, Dr. González has studied biogeographic patterns in shallow invertebrates of the Southern Ocean. His line of research has been focused on understanding the evolutionary processes involved in the origin and diversification of particular groups of Antarctic and sub-Antarctic mollusks. He has also studied how Quaternary glacial events have impacted patterns of diversity, structure, and genetic connectivity in different provinces of the Southern Ocean.
Dr. González is currently an associate researcher at the Faculty of Sciences of the Universidad de Magallanes (UMAG), director of a Fondecyt initiation project on mollusks, a young researcher at the Instituto Milenio de Ecología y Biodiversidad (IEB), and a Latin American representative of AntECO (State of the Antarctic Ecosystem), one of the scientific programs of the Scientific Committee on Antarctic Research (SCAR).
