Omar Omar Ohrens, Ph.D. 2018

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.

“Drew” Drew Bantlin, M.S. (Ph.D. candidate)

Drew earned his M.S. in 2017 in Environment and Resources from UW-Madison. Drew's research focuses on the effect of African lion reintroduction to Akagera National Park, Rwanda. He is exploring the trophic cascade hypothesis, that top carnivores have top-down influence on other species in an ecosystem. He is examining how lions may influence the behavior of other species in the park, which may in turn have effects on plant communities and ecosystem processes. Much of his field work involves direct observations of the lions and their prey, camera trapping, and analysis of GPS collared animals. In addition to research, Drew also assists Akagera with other research projects, including assisting with monitoring the newly reintroduced black rhinos, conducting population surveys on the ground and in the air, and collecting data on the demographics of elephants, giraffes, hyenas, and leopards. Prior to coming to Akagera, Drew has had field experience working with gray wolves, mountain gorillas, chimpanzees, and numerous monkey species.

“Francisco” Francisco Santiago-Avila, MPP, MEM (Ph.D. 2019)

Fran holds Masters degrees in environmental public policy as well as environmental management from Duke University. His recent research has focused on valuation of non-wood forest wealth, the prioritization of ecosystems for conservation in Latin America and the Caribbean, and measuring the impact of protected areas on land cover change. As part of CCL, Fran's research has revolved around the integration and application of environmental and animal ethics to coexistence with wildlife, and the evaluation of the effectiveness of lethal and non-lethal methods to prevent conflicts with large carnivores (the gray wolf, in particular). His main objective is to reform wildlife management by embedding in it the much needed acknowledgement of moral standing for individual nonhuman animals. Fran's other research interests include: human behavior and attitudes towards animals, conflict-mitigating interventions and legal mechanisms for conservation. His other interests include carnivore behavioral ecology and trophic cascades

“Karann” Karann Putrevu (Ph.D. candidate)

Karann is a computational biologist originally from St. Catharines, Ontario, Canada. He completed his Bachelor of Science with a dual degree in biological engineering and biology at Cornell University. He has a particularly strong passion for tigers and has studied topics ranging from modeling their interspecific conflicts (with leopards in India and wolves in Russia) to the Panthera genus' genetic lineage to the social and political context of the South China tiger's extinction in the wild. Karann is currently working on studying the predator ecology of the Amur tiger in the Russian Far East, applying Bayesian methods to model large carnivore population dynamics, and modeling spatial risk of poaching.

“Naomi” Naomi Louchouarn, MESM (Ph.D. candidate)

Naomi graduated from McGill University in 2014 with a Bachelor’s of Science in Environmental Biology and dual minors in wildlife biology and applied ecology. During and after her Bachelor’s degree Naomi worked on various research projects in Northern Canada, South Africa and Australia. These experiences provided her with the inspiration to pursue research focused on conservation planning and mitigating conflicts between humans and wildlife. Naomi received a Master’s of Environmental Science and Management at UC-Santa Barbara’s Bren School in 2017. Her Master’s research focused on prioritizing land for conservation in Canada’s Mackenzie River Basin to maximize the protection of caribou habitat and minimize economic losses to resource extraction industries in the region. With the CCL, Naomi will lead a project focused on identifying non-economic motivations for poaching of large carnivores (such as grizzly bears) in the North American West. The objective of this project will be to model when and where large carnivore poaching is likely to occur. She is also leading a risk mapping effort to predict where livestock losses to wolves are likely to occur.


Alexandra Pineda Guerrero, Professional Masters in Environmental Conservation (Ph.D. candidate)

Alexandra is a biologist from Bogotá, Colombia and received a Master’s degree of Environmental Conservation at UW-Madison in 2016. She has worked as a researcher in the public and private sector in Colombia. Her work has been related to the ecology of carnivores, conservation planning for tropical mammals and ecosystems, and human-carnivore coexistence and conflicts, specifically related to jaguar and pumas. Alexandra won a scholarship from the Colombian government – COLCIENCIAS- for her Ph.D and she is interested in testing the efficacy of non-lethal methods of preventing jaguar and puma attacks in Colombia.


Abi Fergus (M.S. candidate)

Abi completed her Bachelor of Science in biology at Alma College. She began working with the Bad River Band of Lake Superior Chippewa Indians, located in northern Wisconsin, in the summer of 2017 for her undergraduate senior thesis project. Abi contributed to the update of the Tribe’s Ma’iingan (gray wolf) Management Plan by gathering input from tribal members, non-tribal farmers, and wolf biologists. As a graduate student, she will continue to work with the Tribe and will research non-lethal deterrents to prevent wolf-livestock conflict on farms surrounding the reservation. She is interested in the cultural tie Anishinaabe Indians share with the wolf and in how these and other people have historically coexisted with the wolf. She is also interested in the ecological role that the gray wolf plays as an apex predator and in the theory of trophic cascades.

“Brian” Brian Schuh, Professional Masters in Environmental Conservation

Brian is a wildlife conservationist originally from Santa Barbara, California, who recently completed his Master's degree from the University of Wisconsin-Madison. During his bachelor's degrees in Zoology and Botany, also from UW-Madison, he worked on conservation projects with lumholtz tree kangaroos in Australia, whale sharks in Mexico, and cheetahs in South Africa. These experiences cemented in him a passion for wildlife conservation, particularly focusing on international human-wildlife coexistence with a special interest in cheetahs. During his Master's project he partnered with the Kenya Wildlife Trust (KWT) working to mitigate human-wildlife conflict and understand the population dynamics of lions and cheetahs in the Maasai Mara. Continuing this partnership with KWT, his current research aims at identifying human and natural variables affecting the distribution and abundance of cheetahs in the Maasai Mara and developing management srecommendations for their long term survival.
