PhD Student

I am a PhD student in the Levi Lab. For my dissertation, I will be looking at the community effects of an elk reduction experiment in Starkey Experimental Forest and Range in eastern Oregon.  The elk reduction is part of a long-term research project at Starkey run by the US Forest Service and Oregon Department of Fish and Wildlife. Thanks to the long term nature of the project and the phenomenal efforts of our collaborators, data abounds in the forms of capture histories, collars, cameras, flights, and scats, which will provide ample opportunity for us to look at some fascinating ecology in an experimental setting.

Prior to beginning my PhD, I completed an MS in wildlife biology at the University of Montana. For my masters I tested the robustness of the time- and space-to-event models for estimating abundance of unmarked populations with remote cameras. I looked at both the response to assumption violations and how well they perform in real-world settings when densities and detection rates are low. I also spent about five years working on various field projects between my undergraduate degree at Texas A&M and my masters. The allure of wildlife work was strong, but it needed more math. Now, in my free time, I enjoy long walks through other people’s buggy code, cold beers while I cook, and short runs in the mountains.

PhD Student

I grew up here in the Pacific Northwest and have a B.A. in Environmental Studies from the University of Washington and an M.S. in Wildlife from Humboldt State University. For my master’s research, I studied habitat ecology of North American porcupines in the Tolowa Dunes of northern California. I have also been working on distribution modeling and optimizing monitoring methods for porcupines in light of their apparent declines in western North America.

For my Ph.D. research, I am using passive monitoring and deep learning methods to study wildlife community ecology in forests of the Pacific Northwest. I am co-advised by Dr. Damon Lesmeister with the U.S. Forest Service PNW Research Station, where an ongoing bioacoustics project is being developed to monitor northern spotted owls and other species. We are using convolutional neural networks to automate the identification of a host of different bird and mammal species from acoustic recordings and camera trap images, which allows us to explore dynamics within and between wildlife communities.

PhD Student (NSF Fellow)

Growing up in Minnesota, my love of wilderness was born when I first heard wild wolves howl. By a delightful twist of fate, my Master’s research in the Levi lab now centers on the foraging ecology of coastal wolves on the Alaskan peninsula in Katmai National Park. Using noninvasive DNA sampling and other monitoring techniques, our project will illuminate the fascinating lives of wolves throughout Katmai’s uniquely pristine, bear-dense, and salmon-rich maritime environment.

Although I am principally interested in carnivore behavioral ecology, the eclectic nature of my past research reflects my broad curiosity about wildlife science. As an undergrad at Emory University, I worked on projects concerning the phenology of plant-pollinator interactions, the movement of urban coyotes, bumblebee social learning, Amazonian bat species richness, and salamander population dynamics. Prior to beginning at OSU, I completed a year-long Fulbright research project on arctic fox conservation and interactions among tundra carnivores in northern Norway. I remain excited about many different things within and beyond ecology, including Buddhist philosophy, Cenozoic Era paleontology, and the fantastic world of fungi.

PhD student – NSF Fellow

Originally from Michigan, I have spent the last ten years working for various wildlife research projects that have largely focused on mammalian population dynamics. From studying spotted hyenas in Kenya to cougars and mule deer in northern California, I have spent a lot of time in the field collecting data, sleeping in a tent, and getting to know wonderful people who have inspired my curiosities of wildlife. Most recently I have been working for the Yellowstone Cougar Project which focuses on understanding the role of this solitary carnivore living amongst a diverse predator and prey community.

I am stoked to be joining the Levi Lab to continue working with data from Yellowstone, develop quantitative skills, and learn from lab members who are conducting all sorts of cool science. Specifically, I hope my research improves our understanding of how intact predator guilds can exhibit positive effects on prey communities, and how such interactions are influenced by seasonal weather patterns. Besides wildlife, my other interests involve reading fantasy books, dreaming of snowy mountains with skis on my feet, throwing frisbees, and providing my dog with all the support she needs to fulfill her endless quest of finding the best place to hide bones, sticks, and other valuables found while walking through the woods.

MS Student

The route I took to become a Master’s student in the Levi Lab was fairly circuitous. A large swath of conservation land was my playground growing up and I was academically inclined toward quantitative pursuits but I took a detour through the art world before coming back to computer programming as a webmaster at a software development firm. After a time I decided to pursue something more meaningful so I returned to school and volunteered at the Eagle Creek Fish Hatchery and the Julia Butler Hansen Wildlife Refuge with their Columbian White- Tailed Deer Project. Everything came into place when I realized that I could use my computer programming and quantitative abilities to help protect and preserve the natural world.

That we can use code to develop methods to analyze genetic code is fascinating to me. Continued advancements in sequencing technologies have made complex genetic analyses accessible to resource-deprived wildlife organizations and it is my goal to facilitate wildlife management and conservation efforts by developing novel molecular methods to monitor wildlife.

MS Winter 2019 (Now Executive Director of Takshanuk Watershed Council)

Growing up in upstate New York and spending lots of time tromping through streams and fields instilled a wonder about ecology. This continued through my undergraduate studies at the State University of New York College of Environmental Science and Forestry (SUNY-ESF, “stumpies”) where I majored in Environmental Science with a focus on watershed science and engineering. I then found my way to Alaska and have spent the past 7 years working for a small non-profit watershed council in Haines. My Masters research takes place in the large glacier fed rivers near Haines, AK. The focus is a small anadromous smelt species called eulachon or hooligan (Thaleichthys pacificus). Eulachon are a very important subsistence species for the Alaskan natives and vital forage fish for marine mammals and sea birds, however there is relatively little ecological knowledge about the species – limited population data, poor understanding of marine habitat, and unknown fidelity to natal streams, etc. My research will calibrate the concentration of environmental DNA (eDNA) against estimates of eulachon biomass from mark-recapture and catch-per-unit-effort methods. This relationship will provide insight into population monitoring techniques that can be implemented regionally.

Former Postdoctoral Research Associate, now postdoc at UC Santa Cruz

For many species, fitness is a function of an individual’s ability to match his or her behavior to available conditions. Thus in making decisions that affect their fitness, animals translate the conditions they experience into demographic consequences at the individual and population levels. I’m interested in: 1) exploring the causes and consequences of animal behavior, particularly with regards to movement; 2) using an understanding of the attendant cues, costs and incentives to enhance approaches to studying species distribution and abundance; and 3) applying 1&2 to inform management and conservation actions. These questions surrounding the extent of a species ability to adapt behaviorally to changing conditions are at the heart of understanding population-level vulnerability to anthropogenic change. In the service of these goals I’ve also taken an interest in developing platforms that improve the dissemination and application of important quantitative tools.

My PhD research focused on understanding how partial migration is maintained in federally-endangered Sierra Nevada Bighorn Sheep, but also included quantifying migratory behavior is several other ungulate systems. As part of this research I wrote the R package “migrateR”, which improves and automates model-driven methods for movement classification (available online at: https://github.com/dbspitz/migrateR). As the Jack Ward Thomas Postdoctoral Fellow, I now contribute as a member of the Starkey Project. This collaboration extends my interest in ungulate movement ecology to a broader range of spatial and temporal scales, from quantifying the long-term effects of fire history on ungulates to evaluating the fitness consequences of fine-scale strategies for predator avoidance.

MS Spring 2018 (Now Wildlife Biologist with Confederated Tribes of the Grande Ronde)

I grew up outside of Chicago and spent my youth wandering the forests and lakes of the upper Midwest.  After receiving my undergraduate degree from the University of Vermont I moved west and have worked in many different places.  Most of my work has been focused on mustelids, and spotted owls in northern California and Oregon.  In my spare time I enjoy hiking, fly fishing, and spending time with my dog, Finn.

My master’s thesis in the Levi lab focuses on the distribution of fisher (Pekania pennanti) in southwestern Oregon and is nested in a multi-species monitoring framework.  Fisher are rare forest carnivores with relatively unknown distributions in Oregon.  I use remote cameras and genetic sampling to survey landscapes for these animals and ask additional questions about the ecology of carnivore guilds in the area.

MS Fall 2017 (now instructor at Oregon State University – Cascades)

I have worked in various fish and wildlife positions across the Western United States. I worked for the Birds and Burns project at Montana State University where I earned my B.S. in Fish and Wildlife Science. After graduating, I interned at an environmental consulting company in Tucson, AZ, where I participated in a wide variety of avian, reptilian and plant surveys. Over the last couple of years I have been working at a pharmaceutical research and development company in Bend, Oregon, but I am very excited to get back into wildlife at OSU.

My Master’s project in the Levi lab focuses on bears’ roles as seed dispersers in the Southeastern Alaskan ecosystem. Specifically, I am using qualitative and quantitative methods to determine which species consumes the largest proportion of berries from the widely dispersed shrub, Oplopanax horridus (Devil’s club). Due to the nature in which bears consume O. horridus, I am also researching this shrub’s potential to noninvasively monitor bear movement and density in this habitat.

MS Winter 2017 (now Wildlife Biologist with Alaska Department of Fish and Game)

Over the past five years I have been involved in various wildlife projects throughout the Western United States. I began working with small mammals and pumas while pursuing my Bachelor’s degree in Environmental Studies at the University of California Santa Cruz. After completing my degree, I spent the next three years deploying GPS collars to track the survival, feeding behavior and reproductive success of pumas in central California. I have also worked with wolves, golden eagles, black swifts and other wildlife throughout Montana, Wyoming and Colorado.  I am broadly interested in carnivore ecology, behavioral ecology and conservation efforts.

As a Masters student in the Levi lab, I will be investigating the ecological role of bears in the dispersal of a variety of fruiting plant species in Southeast Alaska.  The tremendous amounts of fruit consumed by bears results in seed filled scats throughout the landscape, which may provide a feasible foraging resource for small mammals during times of food scarcity and an important form of seed dispersal. Understanding the interspecific interactions between bears and small mammals will aid in a better understanding of the potential cascading effects of bears on small mammal populations and how it may impact avian predators and mesopredators.
