Research Group

Some present opportunities to join our group

I am not actively seeking new graduate students at this time (for 2022).

Research Students
I do not tend to have a very large group size, mostly because of the high costs of northern research, and that I like to work closely with students and commit sufficient resources to do a project well.  You can read through some of the past student projects below to get a sense of the range of things that I tend to encourage students to pursue.  It’s unusual that I will have more than one or two graduate positions available in any given year. 
However, if you are competitive for scholarships or have significant experience carrying out research than I’m happy to discuss potential projects with you.  At the moment, most of my research is focused on upper Mackenzie basin, the area from the lower Athabasca valley to the central Mackenzie valley, though I do have several projects going on in the Yukon where the majority of my research has taken place.
In 2019, we opened the Permafrost Archives Science Laboratory (PACS Lab) which is an ice-core styled lab focused on Permafrost characterization and analyses of permafrost-preserved records for a variety of applications.  This is a state-of-the-art lab (see News) that will have many opportunities for novel projects related to permafrost science.

I encourage students to develop their own projects- the main caveat being that it must fit broadly within the goals. and be consistent with the funding, I have available. But contact me if you think you might be interested. Be aware, however, right now my group is near capacity- that makes it harder to find a spot, but not impossible…
