Kellen Nelson is a postdoctoral fellow at the Desert Research Institute with expertise in forest ecology, disturbance ecology, landscape ecology, and spatial ecology. He holds a BS (2004) and MS (2009) in Forestry Biology and Forestry Ecology from Colorado State University, and a PhD in Ecology from the University of Wyoming (2017). Past investigations include evaluating how natural disturbances (e.g., bark beetle outbreaks and wildfire) and forest management activities affect stand and landscape patterns of tree demography, biomass fuels, fuel moisture, and carbon storage. Current investigations include investigating the successional dynamics of fuel loads, fuel moisture, and fire behavior in post-fire forests, the effects of prescribed fire on fuels and plant communities in upper montane Sierra Nevada forests, and the development of aerial survey, sensing, and sampling methods using small unmanned aircraft systems (sUAS).
