We are interested in all manner of things associated with arthropods at low temperatures (and sometimes at high temperatures, too!).  Below you can read about some of the things happening in the lab. Watch this space and the publications page to see how things develop.

My interests are broad, and as a result we have a lot of different projects going on in the lab.  Almost all of it is around the theme of insect low temperature biology (of course), but we do make occasional forays elsewhere - for example, we have had a few projects on snails and other gastropods, and (with PhD student Susan Anthony) we are starting to explore the thermal biology of spiders and other arachnids, mainly from the Canadian Arctic.  Some current projects (in no particular order):
  • Mechanisms underlying insect freeze tolerance - That's why I started studying insects in the first place, and we are currently approaching this with renewed vigour, since we have some great new model systems in which to study it.
  • Multiple stressors during overwintering - Winter brings with it lots of stressors besides cold - we are exploring the interactions between cold, immune and chemical stress in the hopes of figuring out how to predict the impact of interacting stress.
  • Temperature effects on the immune system and microbiome - We are not alone!  All animals carry with them a huge community of symbionts and potential pathogens.  It'd be great to understand how these little creatures interact with their hosts to modify responses to the environment.
  • Ion and water balance in the cold - For five years or so, our lab has been at the forefront of understanding how insect ion and water balance is affected by low temperatures.  Plenty of fun things going on still!
  • Cold tolerance of northern arachnids - spiders are the dominant predator of the Arctic tundra, where they might experience temperatures spanning more than 60 °C.  We have no idea how they deal with this, but would love to find out...
  • New tools for studying insect cold tolerance -  Exciting things are afoot when it comes to conducting manipulative experiments to understanding the mechanisms underlying insect cold toerlance. Watch this space for RNA-Seq, RNAi, CRISPR/Cas9 and all sorts of other goodies!
  • Overwintering energetics - We've been working on energetics and metabolism of overwintering insects (and frogs, once), and are continuing to do this, mainly with pest insects at the moment.
