Expertise

I am an Atmospheric scientist with an interest in studying interactions and feedbacks between wildfires and the changing climate. I am currently working with HIGRAD/FIRETEC on exploring the effects of complex topography on fire behavior, something that is not yet included in climate and Earth System models used to project wildfire behavior under climate change.

Past experience also includes:

  • Extensive experience working with climate model data archived as part of CMIP3 and CMIP5
  • Expertise using various climate feedback quantification methods
  • Building energy balance models of climate, and modifying and running more complex global climate models
  • Dabbling in Bayesian inference and uncertainty quantification
