Research in the lab focuses on the intersection of disturbance dynamics, ecosystem thresholds, and coupled human-natural systems. We examine how global environmental change (including shifting fire cycles) alters plant communities and ecosystem function. Our research balances cutting-edge fieldwork with analysis of global ecological data to examine how human changes to fire patterns are encouraging forest-savanna transitions, degrading ecosystems, and increasing greenhouse gas emissions. Together with an international community of collaborators, we work across disciplines and scales – from individual organisms to entire ecosystems.
One PhD position will be part of a larger collaborative project exploring the climate and land use drivers of invasive-grass fueled fires across the western U.S. Non-native, invasive grasses are increasing fire activity globally, yet the mechanisms driving the initiation and perpetuation of novel fire regimes remain largely unknown. This project will use remote sensing and spatial analysis to investigate the climate and land-use
mechanisms that promote fires in invaded and native ecosystems – for one of the most prominent cases of a potentially irreversible grass-fire cycle. Cheatgrass (Bromus tectorum), which was introduced to North America in the mid-1800s, now dominates over 40,000 km2 of the intermountain west. This collaborative research project will address the following questions about how climate, land use, and fire interact across invaded and native ecosystems of the intermountain west: i) How do fire regimes and fire probability vary in invaded and native ecosystems? ii) What are the climate and land-use predictors of fire activity in these landscapes? iii) What is the geography of current and future fire risk, under mid-century climate and land-use change scenarios? (This position will be supported through a NASA-supported Research Assistantship and department Teaching Assistantship, which covers tuition and stipends.)
Other PhD opportunities exist on changing fire dynamics, but are dependent on strong student initiative and creativity. Please see the Fire Works Lab website for other current research themes. I am open to student proposals to explore questions within the scope of my overall research program. There are opportunities for highly competitive students to get support via Teaching Assistantships, or other outside funding.
