My research broadly address agroecology and invasive plant species ecology issues including: (1) ecological weed management and fitness costs of herbicide resistance in weeds, (2) ecological impacts of invasive plant species including altered soil chemistry, effects on plant community composition, and effects on multitrophic interactions including fungi, viruses, biological controls, and  pollinators, (3) impacts of fire and climate change on cheatgrass invasion, and (4) effects of climate change on crop-weed-disease interactions.
