Plants hate bauxite residue.
Soil, it must become.
University of Western Australia
Thesis title: ‘A pedogenic treatment for bauxite residue mud’
My PhD aimed to identify the best treatments for remediating bauxite residue mud (also known as ‘red mud’, which is basically the leftovers after processing aluminium ore) deposits so that the residue approaches something like a natural soil and can support a plant cover.
Where, oh where, is brome?
Can you tell from this image?
Better check the ground.

Title: Identifying Annual Brome Within Joshua Tree National Park
I used remote-sensing techniques to produce maps of potential annual brome presence in Joshua Tree National Park in order to support land management and fire mitigation efforts. Annual brome is a non-native invasive grass that prevents the growth of native plants and serves as a highly flammable fuel that increases the frequency and scale of devastating wildfire.
Los ciénegas –
how can they withstand big floods?

Dissertation Title: Wetlands as an alternative stable state in desert streams
My dissertation evaluated the process of wetland formation in desert streams in the context of alternative stable state theory (‘tipping points’), and demonstrated that plants, at sufficient density, can stabilize desert stream channels and allow the development and persistence of wetlands (ciénegas).
Marine microbes eat
that sometimes they don’t.

I measured the rates at which dissolved polysaccharides are degraded by microbes in seawater. Differences in those rates among locations suggest that the reactivity of dissolved organic matter in seawater is determined by the nature of the microbial community as well as the chemical characteristics of organic matter. If seawater microbial communities in the Arctic Ocean begin to access a wider range of dissolved organic molecules as temperatures warm in the future, more organic matter may be converted to carbon dioxide in the Arctic Ocean.

Swarmed with evolving critters.
These things breed like mice!

My dissertation was “Rodents of the La Venta fauna, Miocene, Colombia:
biostratigraphy and paleoenvironmental implications.” Using
screenwashing and surface collection, we found abundant and diverse
fossil rodents, including several new species, and measurable turnover
through the section. All belong to clades indigenous to South America,
with no indication of interchange with North America as of 12 million
