Chris Warner has been professionally involved with the national service movement and environmental stewardship for more than two decades. After graduating from Villanova University with a BA in Sociology (1998), Chris coordinated environmental education activities for EPA’s Mid-Atlantic Region for two years when he served as an AmeriCorps VISTA volunteer. As an Environmental Management Fellow with EPA’s Chesapeake Bay Program, Chris supported several multi-jurisdictional committees whose mandate is to establish policies that aim to improve the water quality of Chesapeake Bay and to manage the Program’s congressionally appropriated annual budget. After relocating to the mountain west in 2002, Chris received his MA in Political Science (Environmental Policy) from the University of Nevada, Reno in 2005. Since graduating from UNR, Chris has spent the entirety of his career at Great Basin Institute, collaborating with colleagues to develop and enhance resource management direct service programs.

Associate Director, Terry Christopher, is proud to be from the great state of Texas, just ask him! He was born in Wichita Falls and spent most of his childhood in north Texas. His love of animals and wildlife was ingrained early on, and some of his fondest memories are of running around catching ornate box turtles and horned lizards (horny toads) on the farm. Living in El Paso, Texas for four years and spending three years in northern Alberta, Canada only strengthened his love of the outdoors and vast open spaces. (Those who know Terry find it hard to believe he lived in Canada; he’s way too much like the ectotherms he works with.) Terry attended Texas A&M University and, while at the campus on Galveston Island, he became involved with the Texas Marine Mammal Stranding Network, a non-profit recovery organization, and the Kemp’s Ridley Sea Turtle Head Start program. For four years, he coordinated volunteers to recover whales and dolphins stranded along the Texas coast. Although he loved these programs, his first love was tortoises, and he continues to strive for their conservation.

In 1994, Terry migrated westward to run the Smithsonian Institution’s Desert Tortoise Nutrition program. Over the next 11 years, Terry conducted nutritional research on desert tortoises in Nevada, California, Utah and Arizona. He said he never planned on being a botanist but studying a desert herbivore quickly changed his mind. After a brief stint running a turtle and tortoise conservation center in California, Terry came to GBI as a Research Associate helping to run the Desert Tortoise Conservation Center and coordinating the USFWS Desert Tortoise Line Distance Sampling project. In fall 2008, he stepped into the role of Associate Director, overseeing GBI operations in southern NV. He brought his knowledge of the southwest and strong relationships with project partners in the south to GBI. He continues to run the desert tortoise monitoring program, refusing to give up that which brought him to the west. While in Nevada, he fell in love with his future wife (not only the desert), had three kids, and has made southern Nevada his home.

Dr. Lynn Zimmerman is the Director of Research at GBI and specializes in physiological ecology and conservation biology, particularly including habitat requirements, environmental resources, and ecophysiological consequences of environmental modifications. Her formative years were spent observing local habitats from tree height and roaming the fields and forests of western New York, wanderings that eventually led to the Mojave Desert and studies of the thermal and nutritional ecology of herbivorous reptiles for a Ph.D. in Biology. Lynn’s first experience with hypothermia was on the summit of Long’s Peak in the Colorado Rockies, and brushes with hyperthermia have accompanied reptile sampling in the deserts of southern California and Nevada. She enjoys testing her thermal tolerance limits while backpacking, hiking, snow shoeing, running and biking. Lynn has an abiding fondness and respect for animals, and is happiest when among them in their natural habitats. Dr. Zimmerman taught and conducted research on animal physiological ecology for 25 years before joining GBI in 2007. In the Research Associate program, Lynn is principally involved in oversight and implementation of projects involving wildlife monitoring and habitat assessment. She has served as Principle Investigator on a rangeland studies related to fire disturbance in the Great Basin and the Desert Southwest that improves understanding of adaptive management practices. She has been involved with AIM since its inception at GBI in 2011 to support aspects including design, training, data management, and reporting.
