I am a native New Mexican born and raised in Stanley, NM. I received a B.S. in Wildlife Science from New Mexico State University. Currently I am pursuing a M.S. in Natural Resources Management from New Mexico Highlands University. In addition to my studies, I also serve as an advocate for a USDA funded grant that encourages underrepresented minorities to pursue careers in the natural resources field. I have worked for both federal (Bureau of Land Management) and state (New Mexico Department of Game & Fish) agencies conducting a variety of cultural and wildlife research. My hobbies include hunting, camping, skiing, building, traveling, and horseback riding. I am passionate about wildlife management, conservation and environmental restoration.

Jean-Marc Andre

Jean-Marc Andre

Originally from Belgium where I gained my Agronomist Engineer Degree (Gembloux University) upon studying the impacts of herbivory, bushfires and climate on the vegetation of the Virunga National Park in eastern Democratic Republic of Congo, I then headed to Mozambique for elucidating the conservation status of the endangered African wild dog in the center and North of the country. This gave me the opportunity to uncover a small forest-dwelling population of this emblematic carnivore close to the Zambezi River estuary. For my MS degree, I am currently working on analyzing data on its demography, ranging, ecology and genetics collected over nearly a decade

Matt Boggie

Matthew Boggie

Matt hails from the desert southwest where completed a BSc and MSc in wildlife ecology from the University of Arizona. His previous research examined factors that influence the demographic attributes and behavior of predatory birds inhabiting heavily urbanized environments. He is broadly interested in scientific research that strives to forge a connection between responses of wildlife to environmental change and the mechanisms that drive ecological patterns at local and landscape scales. He is most interested in addressing conservation challenges that advance understanding of how fluctuations in habitat availability relate to the distribution and population dynamics of wildlife. For his doctoral research, he will investigate the winter ecology of the Rocky Mountain Population of Greater Sandhill Cranes in the Middle Rio Grande Valley and assess how future landscape level changes may impact the population.

Scott Boyle

Scott Boyle

Scott was born and raised in Colorado where he grew up camping, fishing, and hunting. These activities sparked his interest for a career and he went on to receive his B.S. degree in Fish, Wildlife, and Conservation Biology with a wildlife concentration from Colorado State University in Fort Collins, Colorado. His primary work experience has included working with several large mammals including moose, deer, and elk studying neonate and adult survival, habitat selection, and mortality. Along with his work on large mammals, he also worked with chukar partridge and assisted in several other carnivore and spatial use projects. Through this time he has developed a research interest in habitat selection, predator-prey interactions, cause-specific mortality, and population dynamics.

Chris is interested in avian ecology, restoration ecology, and outreach that can help create a better informed, conservation minded public. After graduating from NC State, he worked as a technician for the NC State Cooperative Fish and Wildlife Research unit on the North Carolina outer banks. He has spent the last four years as the field ecologist for a land trust in the Southern Appalachians, executing habitat management and wildlife monitoring projects around the Highlands of Roan. Chris joined the Carleton lab in 2014 and studies Band-tailed Pigeon migration and recruitment at NMSU. 

Zack Farley

Originally from Chicago, I received my B.S. in Natural Resources from The University of Vermont. Since graduating, I have worked as a technician on multiple research projects primarily interested in carnivore ecology, predator-prey interactions and conservation. I am currently a M.S. student working in the Gila National Forest looking at the costs of reproduction for elk in relation to predator density. Outside of wildlife work, I enjoy rock climbing, mountaineering, hunting and traveling.

Andrew Lawrence

Andy's interest in wildlife biology stems from his formative years spent on a farm in northern Illinois. His exposure to the outdoors through hunting, fishing, and exploring the surrounding land instilled a deep curiosity in the ecological processes that influence a species' success or decline. As an undergraduate at North Carolina State University, Andy worked on several state, federal, and university projects that sought to bridge the gap between human development and wildlife conservation. After graduating in 2010, he worked as a avian research technician for the North Carolina Cooperative Fish and Wildlife Research Unit and the North Carolina Wildlife Resources Commission. Andy joined the New Mexico Cooperative Fish and Wildlife Research Unit at NMSU in 2012 to research Lesser Prairie-chicken ecology and pursue his PhD.
