I earned a BS in BioEngineering from the University of Pittsburgh and masters in Ecology at Colorado State University.  I am interested in trophic cascades. During my master's research, I worked with Dr. Liba Pejchar to investigate the impacts of elk browsing and riparian willow restoration on bird communities in Rocky Mountain National Park. Throughout my masters, I also worked at the national park supervising data collection for the park's Elk and Vegetation Management Plan, overseeing vegetation monitoring, elk exclosures, and elk counts. My PhD research with Dr. Aaron Wirsing is exploring possible trophic cascades that may be occurring with the recolonization of grey wolves in north central Washington. I am interested in learning how this coursing predator may influence deer foraging behavior, diet composition, and plant browse which may lead to changes in vegetation structure or composition. I am passionate about citizen science, environmental education, and science communication.

My goal is to conduct wildlife research that not only advances our understanding of wildlife species and their ecological roles but also results in the development of scientific and practical methods of management and conservation. I am particularly interested in noninvasive carnivore research and spent the last three years studying wolverines for the North Cascades Wolverine Study and Conservation Northwest. While I was chasing wolverines around in the mountains, I earned a BS in Wildlife Conservation from the University of Washington’s School of Environmental and Forest Sciences (SEFS) in 2014. In 2015, I received a recruitment fellowship to return to SEFS as a master’s student in the Predator Ecology Lab, where I am studying carnivore habitat use, relative activity, species composition, and diet along the urban-to-wildland gradient of western Washington. My research will help illuminate how wildlife species exist along a gradient of human influence and inform future land-use and development planning.

I am a Ph.D. Student and NSF Graduate Research Fellow studying the ecology of snow leopards, wolves, ibex and argali in the Pamir and Tien Shan Mountains of Central Asia. The direct and indirect interactions among the carnivores and ungulates in this ecosystem have serious implications that can inform better hunting and husbandry practices to benefit local communities and wildlife alike. Using a combination of non-invasive genetics, camera trapping, GPS telemetry, and direct observation, I will create spatially explicit estimates of carnivore and ungulate demographic and behavioral parameters against which I will be able to compare habitat selection, reproductive success, survival, and other questions of interest.

I graduated with a B.S. in Wildlife Science from UW in 2008, and I completed my M.S. in Wildlife Ecology at the University of Delaware in 2014. Prior to grad school, I worked for 4 years as a Wolf Recovery Biologist for the Nez Perce Tribe in Idaho. My research interests include development of non-invasive techniques for investigating rare and elusive species, hierarchical modeling in ecology, carnivore spatial ecology, behavioral ecology, and international conservation.

I am a Ph.D student investigating the characteristics of foraging habitat for the state-endangered Canada lynx, the drivers of survival for snowshoe hares (the main prey of lynx), and how predator type and prey characteristics relate to kill-site habitat in Washington state's southern boreal forests. The methods I used to collect data over my several years in the field included using forensics to determine the responsible predator at kill sites, live-trapping hares, telemetry monitoring, camera trapping, forest measurements, pellet surveys, and snow tracking.

I received my M.S. at UW examining the effectiveness of a saliva-swabbing technique at wildlife kill sites with minimal prey remains. Prior to graduate school, I obtained my Bachelor's from UCLA, studied abroad in Tasmania, worked as a field technician, and spent a few years as a biologist for an environmental consulting firm, all of which gave me experience with many taxonomic groups. Although I have numerous research interests, I am most interested in predator-prey interactions, sensitive species, and how behavioral ecology can inform conservation and management decisions. I am also passionate about teaching, outreach, and encouraging people of all backgrounds to not be intimidated by ecology or science in general.

I am a second year Masters and Ph.D. student and NSF Graduate Research Fellow studying how the transition from wildland to urban environments shapes cougar hunting behavior.  In Washington, cougars occupy landscapes adjacent to residential development.  The ecology and behavior of cougars is shaped in part by human population size, distribution, and activity.  Consequently, successful management and conservation of these species requires an accurate understanding of how these factors influence cougar space use, foraging ecology, and interactions with people.  The goal of my research is to understand how landscape features, particularly patch size, patch shape, and understory characteristics, influence where cougars choose to hunt for prey, and whether tendencies change near residential areas.

My field work involves radio telemetry, GPS collaring, and kill site analysis.  Prior to graduate school, I graduated from Williams College in 2011 (highest honors) with a BA in biology and environmental studies.  After Williams, I worked as a Divemaster for St. Croix SCUBA in Hudson, WI, doubling as an assistant to instructors and as a member of a research team managing invasive Myriophyllum species in Perch Lake. In the summer of 2012, I worked as a field intern for the Northern Divide Grizzly Bear Project in Glacier National Park.  After working on the brown bear project, I spent 10 months In Liwonde National Park, Malawi, researching roan antelope population stability through a Fulbright grant.      
Lauren Satterfield
I​ am a PhD student studying the effects of wolf recolonization on mountain lion ecology and resource selection in Washington State under Drs. Aaron Wirsing, Brian Kertson, and Thomas Newsome. 

While completing a bachelor’s degree in Mathematics from Mount Holyoke College, I was motivated to travel and spent a semester abroad focused on Tibetan and Himalayan Studies with the School for International Training in India and Nepal. My work there included a survey of snow leopard-pastoralist conflict mitigation measures in Hemis National Park and the surrounding areas of Ladakh, India. I advanced my field skills as a technician on a mountain lion prey study in Bighorn Canyon National Recreation Area, which spans Montana and Wyoming, before entering graduate school. During my master's at the University of Georgia, I worked with Drs. John Carroll and Clint Moore to study occupancy, temporal partitioning, and bait preferences of the carnivore community in the Tuli block of eastern Botswana using camera traps. While in Botswana, I acted as a teaching assistant for an undergraduate study abroad course. Students learned about topics and challenges common to international conservation while assisting with leopard and lion research led by the Northern Tuli Predator Project. After graduation, I moved to Cyprus on a Fulbright scholarship working with local biologists to study cave ecology and promote cave conservation on the island. My research interests focus on using a combination of advanced analytical methods and fieldwork to study predator ecology, human-wildlife conflict, and ecosystem health, both domestically and internationally.

I am a fourth year PhD student co-advised by Aaron Wirsing and Dee Boersma in the Department of Biology. I got my BS from the University of Washington in 2006 and spent the next four years working for the Magellanic Penguin Project both in Seattle and at the field site at Punta Tombo, Argentina. I then spent a year in Kenya working for Kay Holekamp and the Spotted Hyena Project at their field site in the Masai Mara. The central focus of my dissertation research is looking at variation in aggressive behaviors between individual penguins. I am interested in how differences in aggression between individuals affect mating patterns and fitness. I am also interested in predation patterns on both adult penguins as well as on penguin nests. My work is a mixture of behavioral ecology, landscape ecology, and conservation.

​Understanding how and why animals move across space and time are central themes in ecology, and intuitively important for conservation planning. My research to date has focused on investigating these topics in the marine environment, with an emphasis on their application to the management of shark and ray species. I use a wide variety of data and tools to answer these notoriously elusive questions, including field observation data, controlled enclosure experiments, computer simulations, and spatially-explicit models. During my Master’s at Delaware State University (advised by Dr. Dewayne Fox), I used tagging data to identify Habitat Areas of Particular Concern for sand tigers (Carcharias taurus) and explored ways to lower catch rates of protected shark species in recreational fisheries. For my PhD at Florida International University (advised by Dr. Yuying Zhang), I focused on reducing biases in visual surveys of elasmobranchs, and improving survey designs through artificial intelligence models. My work was conducted in collaboration with the Heithaus lab, as component of Global FinPrint: the world’s largest global assessment of reef shark populations. As part of my PhD research, I led the world’s first full-spherical baited video survey of elasmobranchs, focusing on the small French Polynesian atoll of Tetiaroa. Tetiaroa’s small size, isolation, minimal human disturbance, and protected elasmobranch populations made it an ideal study location by allowing us to observe the behavior of apex predators in a relatively undisturbed environment. As a postdoctoral researcher in the PEL, I will be building off this initial work and explore how the space-use of both aquatic and terrestrial predators varies across different life-stages, and how these dynamics influence prey species’ movement choices. A key component of this research will be collaborating with the Tetiaroa Society and the Centre de Recherche Insulaire et Observatoire de l’Environnement (CRIOBE) to establish a large passive-acoustic telemetry network within Tetiaroa and nearby islands. Using this network, we will be able to track the movements of telemetered sharks, rays, teleosts, and other marine species in relation to one another over the course of months and even years! With this invaluable dataset, we hope to improve our understanding of how nursery habitats serve different elasmobranch species throughout various life stages, and set a baseline from which to explore the impact of future environmental changes (e.g., climate change, habitat loss).
