Adrian Treves

Professor and Founder of the Carnivore Coexistence Lab

Adrian Treves conducts independent research and advocates for future generations of all life, for scientific integrity, and for sovereign publics worldwide. He studies and speaks about the public trust doctrine and intergenerational equity around the world More on public trust doctrines and intergenerational equity here. Adrian earned his PhD at Harvard University in 1997 and is a Professor of Environmental Studies at the University of Wisconsin–Madison and director of the Carnivore Coexistence Lab since 2007. For the past 27 years, his research focuses on ecology, law, and human dimensions of ecosystems in which crop and livestock ownership overlaps the habitat of large carnivores from coyotes up to grizzly bears.

The University of Wisconsin–Madison occupies ancestral Ho-Chunk land, a place their nation has called Teejop (day-JOPE) since time immemorial. In an 1832 treaty, the Ho-Chunk were forced to cede this territory. Decades of ethnic cleansing followed when both the federal and state government repeatedly, but unsuccessfully, sought to forcibly remove the Ho-Chunk from Wisconsin. This history of colonization informs our shared future of collaboration and innovation.Today, UW–Madison respects the inherent sovereignty of the Ho-Chunk Nation, along with the eleven other First Nations of Wisconsin.

“Drew” Drew Bantlin, M.S. 2016 and Ph.D. candidate currently

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.

“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, 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. Her projects are on Range Riders protecting cattle from wolves and grizzlies ( in

Our project here is a gold-standard experiment with Range Riders. She also worked on Mexican wolf mortality (


Alexandra Pineda Guerrero, Professional Masters in Environmental Conservation 2016 and Ph.D. candidate currently

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.

“Brian” Brian Schuh, Professional Masters in Environmental Conservation 2018 and PhD candidate currently

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.

“Sam” Sam Hermanstorfer, Undergraduate B.S. 2020 and Masters candidate currently

Sam is a wildlife conservationist originally from Castle Rock, Colorado. He graduated from the University of Wisconsin-Madison with a Bachelor of Science in Conservation Biology and Environmental Studies and is now pursuing a Master of Science Degree in Environment and Resources. As an undergraduate, Sam volunteered in the Carnivore Coexistence Lab where he remotely assisted with the Akagera National Park project, focusing on analyzing wildlife camera trap photos to quantify behavior changes in response to African lion reintroduction. Sam has a wide base of experiences in wildlife conservation. He interned at Brookfield Zoo in Chicago as a pachyderm zookeeper, where he provided husbandry to eastern black rhinoceroses, pygmy hippopotamuses, and lowland tapirs. He also spent a summer in Stone Harbor, New Jersey, as a coastal bird conservation research intern, focusing his independent research on Fish Crow overabundance and resulting impacts on other saltmarsh species. Sam’s current research takes him to Montrose County, Colorado, to investigate coexistence attitudes between Colorado residents and carnivores, and conduct a non-lethal deterrence experiment.
