He graduated and completed his master’s degree at the Universidade Federal do Rio Grande do Sul (UFRGS) in the far south of Brazil. Currently, he is finishing his PhD on biogeography of Amazonian amphibians at the Universität Trier, in Germany.

Among many projects, he works on the perhaps most successful amphibian conservation program in Brazil: the Admirable Redbelly Toad project. Currently, he collaborates with the Giant of the Pampas initiative, which aims to protect the Ornate Horned Frog in South America.

Since 2014, he has been a member of the IUCN SSC Amphibian Specialist Group, collaborating with its Brazilian regional branch (ASG Brasil). In recognition of his work, in 2017 he was awarded the ACRS Future Leader of Amphibian Conservation prize.

Loving people as much as he loves amphibians, Luis believes education and environmental awareness are essential aspects of any conservation program. He is also very interested in bringing people together and working in collaborative and multi-disciplinary groups. By working with ASA, he hopes to make room for other conservationists from South America, one of the most biodiverse regions of the world, but still underrepresented in conservation teams working at global level.

Berglind Karlsdóttir
Berglind KarlsdóttirCommunications Program Assistant
Berglind first fell in love with amphibians in the rainforests of Ecuador, where she discovered their diversity and importance to the ecosystem, but also learnt about the threats they increasingly face. Following years of travelling and volunteering, Berglind completed a master’s in Conservation Science at Imperial College London. In a recent internship with Durrell Wildlife Conservation Trust, Berglind passionately promoted amphibians and their conservation through blog posts, social media content and presentations. She also published guidelines for improving amphibian captive breeding programmes for conservation, which was done in collaboration with the Amphibian Ark. She currently works on bioacoustic analysis of calling frogs from Madagascar, and recently completed an expedition to Ecuador to search for the remaining population of Podocarpus harlequin frog. They found just one male!

Looking back at her initial encounter with the fascinating amphibians of Ecuador, Berglind is keen to share that sense of awe with the public. She believes that the solutions to global amphibian declines must involve as many people as possible. That’s why she now contributes to the communication and outreach work of the ASA.

Gabby Wild


“Gabby Wild” is considered the “new” face of animal activism. Dubbed the “guardian angel of wildlife”, she founded the 501(c)(3), The Gabby Wild Foundation, Inc. Through her organization, she travels the world to promote animal conservation through creative fundraising and awareness campaigns. Previously, Wild has conducted competitions, challenges, and travel expeditions to places like Thailand to work with elephants, Africa to study baboons, Alaska to tend Iditarod sled dogs, and Ireland to aid horses.

Wild’s most recent campaign involves a cat-walk into the fashion forest. Wearing only one sustainable outfit representing an endangered animal for an entire month for each month of 2012, she has employed high fashion to raise an eyebrow for her furry (and bald) friends. The outfits were predominantly designed and tailor-made by Lifetime’s Project Runway designers. Within the first five months of her campaign, she received over 150 media credits for her efforts, including the NY Times. Rod Manley, SVP of Communications at Giorgio Armani US, has proclaimed the campaign as, “Brilliant! Absolutely brilliant!”

Gabby has been internationally recognized for her philanthropic efforts by organizations such as the Humane Society, GreenPeace, Conservation International, National Wildlife Federation, Natural Resource Defense Council, Arkive, and the International Union for the Conservation of Nature. Among the honors she has received include the “Champion of the Zoological Society of London’s EDGE of Existence Programme” and “Hero of the Revolution” by Sustainatopia. In an effort to marry her dual interest in animal conservation and fashion, she premiered in the fashion world with Luis Valenzuela at TheGreenShows at Mercedes-Benz Fashion Week (February 10, 2012), and has been featured at EarthDayMiami and Fashion Fights Poverty in Washington D.C.

Also a fundamental scientist, Gabby has conducted molecular research since she was 15 years old, conducting her first independent research project on the bacterial composition of indolent eye ulcers of dogs.

Wild has yet bigger ambitions to work not only for animals but directly with animals too. She is a graduate of Cornell University (2011) with a Bachelor of Science in both Biology and Animal Science and currently attends Cornell Veterinary College in pursuit of a degree in veterinary medicine.
