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.
Dr. Guillemin is a specialist in the genetics of alga populations. Throughout her career, she has studied the processes that modify biological diversity, especially in the coastal marine area. Her research has centered on understanding the processes – both natural and anthropogenic – that affect the permanence of macroalgal populations.
Currently, Dr. Guillemin is a researcher in the French-Chilean laboratory UMI, “Evolutionary Biology and Ecology of Algae” (EBEA). She also leads projects on the population genomics of Gracilaria chilensis (known as Chinese moss or sea string; locally, pelillo) throughout the South Pacific and the comparative phylogeography of high-latitude algae.

Claudio González Webar
Dr. González is a Marine Biologist with a Master’s Degree in Sciences, specialization in Genetics, from the Universidad Austral de Chile. He completed his PhD in Biological Sciences, specialization in Ecology and Evolutionary Biology at the Universidad de Chile.
In the past decade, Dr. González has concentrated on studying biogeographic patterns in shallow invertebrates of the Southern Ocean. His line of research focuses on understanding the evolutionary processes involved in the origin and diversification of particular groups of Antarctic and sub-Antarctic mollusks. In parallel, he studies the impact that Quaternary glacial events have had on the patterns of diversity, structure, and genetic connectivity in different provinces of the Southern Ocean.
Dr. González is currently an Associate Professor at the Institute of Marine and Limnological Sciences of the Universidad Austral de Chile (UACH), a Young Researcher at the Instituto Milenio de Ecología y Biodiversidad (IEB), an Associate Researcher for the Antarctic Ring GAB project ACT1722065, and a Latin American Representative to AntECO (State of the Anatctic Ecosystem), a scientific program of the Scientific Committee on Antarctic Research (SCAR).

Kurt Paschke La Manna
Professor at the Aquaculture Institute from the University Austral of Chile. Marine Biologist from the University Austral of Chile and earned his PhD in Natural Sciences at the University of Hamburg, Germany.
Dr. Paschke studies the culturing and reproduction of crustaceans and the physiology of marine invertebrates. His line of research is centered on understanding the effects of environmental factors such as temperature, salinity, and – more recently – the availability of oxygen on the physiology of aquatic invertebrates, especially in the early stages of development.
