Dissolved organic matter dynamics from mountains to sea - James Shanley

Research the movement of organic carbon out of the mountains and into the stream -- the “forgotten flux” of the global carbon budget. Assess how climate extremes, including both floods and drought, will alter carbon and other nutrient cycling. Lead a scientific paper on an aspect of this research that excites you.

Developing optimal post-fire restoration strategies to build ecosystem resilience - Stephanie Yelenik

Grass-fire cycles are a problem globally, contributing to expanding exotic grasslands, decreased forest area, and increased fire frequency/size worldwide. Thus, to create resilience to fire in these landscapes, we need to better understand grass-fire interactions and how to restore communities that can resist grass invasion.

Modeling invasion risk and impacts to inform management responses - Helen Sofaer

Where are invasive species likely to be introduced or become abundant? How should managers respond? On Hawaii and other Pacific Islands numerous invasive species have altered ecosystems, and new species continue to be introduced. Statistical analyses can characterize risk and inform response strategies.
