Thanks for stopping by.
I am an Assistant Professor in the Rubenstein School of Environment and Natural Resources at the University of Vermont.
I use a variety of approaches to answer questions rooted in applied population ecology, conservation biology, and disease ecology. Much of my work involves developing or using innovative quantitative tools to help managers and conservationists make decisions in an uncertain world. You can find my CV here.
I always seek opportunities to show different groups of people how complex, beautiful, and valuable our ecosystems are. Check out my outreach and teaching tab for more on this.
October 2019 - present: Assistant Professor, Rubenstein School of Environment and Natural Resources, University of Vermont.
2017: PhD Fish, Wildlife, & Conservation Biology; Colorado State University
2011: MS Fish & Wildlife Management; Montana State University
Thesis: Implications of a mountain pine beetle epidemic for bird populations
2009: BS Natural Resources; Cornell University
My science is motivated by applied research questions, though the findings often have broad ecological implications. I use carefully designed field studies, laboratory experiments, and model-based techniques to make sense of complicated systems.
Understanding species distributions
Where do we find populations, and why?
Studying populations in flux gives us an opportunity to learn what our world might look like in the future. Some changes happen quickly, for instance when populations are exposed to a novel pathogen. Other changes might be more gradual, as processes like competition or climate slowly cause shifts in species ranges. Whether studying an invader, a population under siege, or a community of species, we can use a variety of tools to understand why populations are shifting and what we might be able to do about it.
Working closely with resource managers yields important insights about the complexities of management decision-making. Developing frameworks that identify plausible management actions for meeting objectives can streamline conservation action. Recently, I have worked on identifying optimal management strategies in amphibian disease systems, which may involve translocations and reintroductions.
Amphibian disease dynamics
Amphibians worldwide are declining at unprecedented rates. An invasive fungus is one culprit that is doing damage in the Rocky Mountains. Though once common in Colorado, the state-endangered boreal toad has disappeared from many high-elevation wetlands coincident with the arrival of the amphibian chytrid fungus. My research identifies the factors that make some boreal toad populations more susceptible to disease than others, and also investigates how to detect the fungus where amphibians no longer exist.

Interested in joining the lab? Check out the information below.
If you're a motivated undergraduate student interested in gaining research experience, let's discuss your research interests and whether they might be a good fit for my lab. Please send me a resume and short email describing your interests. I am especially interested in students with interests in amphibians, disease ecology, and field work in conjunction with learning statistical modeling skills.
As graduate positions become available I will post them here as well as on several job boards. You can learn more about the application process on the Rubenstein School graduate program webpage. In addition, I welcome inquiries from students that are interested in finding alternative funding sources (e.g., NSF GRFP) and who are highly self-motivated.
OUTREACH & SERVICE
Read about Anura, the lonely boreal toad, by clicking here.
Doing nothing is a decision, too - read about taking action despite uncertainty to save amphibians.
Communication is the final step of the scientific method, and I take this step seriously. If our science does not become relevant to others, how can we expect to live in a world where nature is understood, valued, and preserved?
At the University of Vermont, I teach Principles of Wildlife Management (WFB174), Conservation Biology (WFB224), and Field Herpetology (WFB141).
In addition to publishing findings, presenting at meetings, and teaching undergraduate students, I strive to connect science with diverse groups of people, ranging from undergraduate students to policy-makers to children. I'm a proud Letters to a Pre-Scientist and Skype-a-Scientist volunteer.
This July I'll be teaching a course in occupancy estimation at the Smithsonian-Mason School of Conservation. If you're interested or have questions, get in touch!
I have served as the primary instructor for a senior-level capstone course in Wildlife Data Collection and Analysis during CSU's semester abroad program in Todos Santos, Baja California Sur, Mexico.
In addition, I have taught or co-taught several workshops:
- Introduction to R at the annual Wildlife Society meeting (2017 and 2018)
I've served as a TA and partial instructor for the following classes at Colorado State University:
FW661: Sampling and Analysis of Vertebrate Populations
FW370: Design of Fish and Wildlife Projects
FW471: Wildlife Data Collection and Analysis
