Erasmo Macaya Horta
Professor at the Department of Oceanography at the University of Concepción.
Marine Biologist with M.Sc. in Marine Science at the Catholic University of the North. He earned his PhD in Marine Biology at the Victoria University of Wellington, New Zealand. His research is focused on the study of marine macroalgae in areas such as ecology, diversity and molecular biology. He has traveled much of the Chilean coast documenting the diversity of algae.
In order to study the distribution and taxonomy of macroalgae, he has participated in several expeditions to The Juan Fernandez Islands and Easter Island. Currently, he is the director of the ALGALAB, Algal Research Laboratory, University of Concepcion.

Nelso Navarro Martínez
Marine Biologist from the Universidad de Concepción, Master of Science, and Doctor of Science from the University of Sao Paulo, Brazil. Dr. Navarro was the Undergraduate Chair of Marine Biology at the Universidad de Magallanes, where he is currently an Associate Professor and researcher.
Throughout his career, he has studied the physiology of macro- and microalgae as a basis for biotechnology. His research looks at the diversity of Antarctic and Subantarctic marine flora from an ecophysiological and molecular perspective and considers the relationship between the tolerance of reproductive structures for stress and the bathymetric and latitudinal distribution of species at high latitudes.

Nelson Valdivia Lahsen
Professor at the Institute of Marine and Limnological Sciences in the Faculty of Sciences at the University Austral of Chile. Degree in Marine Science with a M.Sc. in Marine Science at the Catholic University of the North. He earned his PhD in Natural Sciences at the University of Bremen in Germany.
Dr. Valdivia has researched changes in species diversity as a response to environmental variables and how modifications in biodiversity and the physical environment affect the functioning of ecosystems.
His current work is focused on how some aspects of climate change affect the interactions between benthic species and how these alterations are reflected in the way both Antarctic and Subantarctic hard-bottom marine ecosystems function.
