Research Methodology

Long-term experimental warming studies in tundra ecosystems using passive warming devices (open-top chambers (OTCs)).
Syntheses of responses to experimental and observed climate change in the International Tundra Experiment (ITEX).
Plant-animal interaction studies incuding grazing effects of muskox and caribou, insect foraging and pollination.
Ecosystem carbon fluxes using closed chamber and eddy covariance methods.
Ecosystem nutrient dynamics using ion exchange membranes and studies of nitrogen fixation using field gas chromatographs.


Complete these steps before you reach out to a faculty member!

Check requirements
  • Familiarize yourself with the program requirements. You want to learn as much as possible from the information available to you before you reach out to a faculty member. Be sure to visit our graduate degree program listings and program-specific websites.
  • Check whether the program requires you to seek commitment from a supervisor prior to submitting an application. For some programs this is an essential step while others match successful applicants with faculty members within the first year of study.
Focus your search
  • Identify specific faculty members who are conducting research in your specific area of interest.
  • Establish that your research interests align with the faculty member’s research interests.
    • Read up on the faculty members in the program and the research being conducted in the department
    • Familiarize yourself with their work, read their recent publications and past theses/dissertations that they supervised. Be certain that their research is indeed what you are hoping to study.
Make a good impression
  • Compose an error-free and grammatically correct email addressed to your specifically targeted faculty member, and remember to use their correct titles.
    • Do not send non-specific, mass emails to everyone in the department hoping for a match.
    • Address the faculty members by name. Your contact should be genuine rather than generic.
  • Include a brief outline of your academic background, why you are interested in working with the faculty member, and what experience you could bring to the department.
  • Highlight your achievements and why you are a top student. Faculty members receive dozens of requests from prospective students and you may have less than 30 seconds to peek someone’s interest.
  • Provide documents that can help the faculty member gauge interest in you as a potential student. This could be a Statement of Intent, a Writing Sample, a list of publications or research endeavors.
  • Demonstrate that you are familiar with their research
    • Convey the specific ways you are a good fit for the program
    • Convey the specific ways the program/lab/faculty member is a good fit for the research you are interested in/already conducting
  • Be enthusiastic, but don’t overdo it.
Attend an information session

G+PS regularly provides virtual sessions that focus on admission requirements and procedures and tips how to improve your application.

Postdoctoral Fellows

1. Synthesis of tundra plant community changes to nearly 30 years of experimental warming using a suite of plant traits, including ecophysiology. PhD or postdoctoral study to involve 2-3 years of fieldwork and working with long-term data sets from an experimental study established in the Canadian High Arctic in 1992. 2. Ecological relaxation response of tundra after 30 years of experimental warming. PhD or postdoctoral study of the removal of experimental warming conditions on tundra plants and soils. 3. Landsape phenology patterns in tundra systems in relation to biological and physical conditions. Combination of plot studies and remote sensing using UAV technology for high resolution (temporal and spatial) analysis of plant phenology across a high Arctic landscape. 4. Phenology, growth and reproductive responses of southern populations in warmed high Arctic conditions: a common garden study. A PhD or MSc project involving the continuation of a common garden experiment established in 2011 with local and southern populations of two common forb species. The studies would involve using the Arctic Tundra controlled environment chamber at UBC. 5. Dendroecological studies using Arctic shrub species. Examination of the growth (and reproduction) patterns in up to four shrub species in response to: a) experimental climate change; b) landscape position, snow conditions and climate. The dendrochronological data can be used to reconstruct climate conditions over the past century.

I support public scholarship, e.g. through the Public Scholars Initiative, and am available to supervise students and Postdocs interested in collaborating with external partners as part of their research.
I support experiential learning experiences, such as internships and work placements, for my graduate students and Postdocs.
I am open to hosting Visiting International Research Students (non-degree, up to 12 months).
I am interested in hiring Co-op students for research placements.
