CCL's work in Chile is led by Omar Ohrens through a Conicyt grant from the Chilean government.

Omar is a Chilean agronomist, who has studied various wildlife in human-dominated landscapes for the last 15 years. His research is focused on human-carnivore conflict and conservation, specifically of pumas, in the region of Tarapacá and Araucanía in Chile. He leads a project to develop verification procedures for livestock loss, mitigate the conflict between pumas and people related to livestock predation, and map risk of puma predation on livestock. Omar won the Becas Chile-CONICYT Scholarship from the Chilean government and his research is funded by the USFWS Wildlife without borders conservation program and a National Geographic Society Explorer Grant. Omar completed his graduate work at CCL, earning a Masters of science in December 2013 and a PhD in May 2018.

Pumas are among the top three most widely distributed wild carnivore on the planet, occurring from Alaska to Patagonia. However they are not thriving everywhere and are protected by law in some regions. There is no evidence yet for breeding pumas in Wisconsin although every year eye-witness reports and other evidence of pumas migrating through Wisconsin are reported. In 2012, CCL entered into a long-term collaboration with Fauna Australis, the laboratory founded by Dr. Cristian Bonacic and his students and colleagues from Fauna Australis of Pontificia Universidad Catolica de Santiago de Chile (photos 1–4).
