I'm interested in genetic diversity at different scales with the aim of improving conservation and restoration.

The role of relatedness in competition between prairie species (2016)

Do plants compete more strongly with closely or distantly related species? Does a non-native species that is closely related to a native species have a better chance of invading? Our group wants to determine if closely related species compete more strongly than distantly related species, based on the hypothesis that related species have...


Broadening definitions of plant biodiversity in restored tallgrass prairies (2015)

The tallgrass prairie ecosystem – a vast landscape of grasses and wildflowers – once dominated the Midwest. However, it’s now one of the most endangered ecosystems in North America. Ecological restoration is the only way to gain new prairie habitat, but restoring a diverse and fully functioning prairie is difficult. This summer, we will be studying metrics of plant biodiversity not usually...


Intraspecific traits of native prairie species (2015)

To address the loss of prairie ecosystems, ecological restoration is increasingly used to conserve native species and regain ecosystem services. However, despite decades of research and applied restoration, restored prairie habitat often falls short of remnant prairie habitat in supporting species diversity and delivering ecosystem services. Between-species and within-species functional trait...


Clonal Growth and gene-flow in in the gypsophile Lepidospartum burgessii (2014)

Lepidospartum burgessii is a rare gypsophiliccshrub with limited distribution in New Mexico and Texas. Most of the known plants are restricted to two large populations, with a few small, isolated populations scattered in the surrounding area. The low recruitment observed in the two largest populations may be due to low seed set resulting from high inbreeding and/or self-incompatibility. We...


Phylogenetic revision of the genera Artocarpus (2013)

The plant genus, Artocarpus is distributed from South Asia east into Oceania, and is the third largest genus (55 68 spp.) in the Moraceae family (fig and mulberry). Artocarpus contains several species of economic and agricultural significance throughout the tropics. While many species produce timber or fruits of regional significance, two species are cultivated throughout the tropics:...
