Current Research

My current research projects include the following: Population ecology of Lepidium papilliferum; Evolutionary and community ecology of the seed bank pathogen Pyrenophora semeniperda on cheatgrass-dominted rangelands; Annual brome biocontrol after wildfire using a native fungal seed pathogen; Ecological genetics of the cheatgrass-head smut pathosystem; Regeneration biology of blackbrush (Coleogyne ramosissima: Rosaceae).

Research Interests

My research interests have been expressed in work focused primarily on the regeneration biology of native Intermountain shrubs, forbs, and grasses, in the context of the ecological restoration of shrublands, including the study of within-species genetic variation in germination regulation and seedling establishment ecology.

    Understanding the effects of slow-growing versus fast-growing pathogen strains may be the key to successfully slow down or stop cheatgrass seed germination.
    The distribution of plant species and populations will likely be reshaped as climate changes. In the intermountain West, shrub species play critical roles in desert and semi-desert ecosystem function.
