Research Interests: 

Work in my lab focuses on the evolutionary ecology of insect-plant interactions. Current research projects include:

  • Impact of outbreak herbivores on aspen and willow
  • Population biology of outbreak leaf miners
  • Invasion biology of Vicia cracca in interior Alaska
  • Causes and consequences of extrafloral nectar secretion by aspen
