Kathe Todd-Brown is a Linus Pauling Postdoctoral Fellow in the Microbiology Group at the Pacific Northwest National Lab. Her research involves computational biogeochemistry across scales, with a specific focus on linking soil carbon processes at the pore-scale to measurements taken at the core and field scales.

Research Interests

  • Computational terrestrial biogeochemistry
  • Multi-scale models
  • Earth system model analysis (land carbon cycle) with particular interest in CMIP
  • Pore-scale process model
  • Carbon cycling

Education and Credentials

  • PhD, Earth System Science, University of California Irvine, 2013
  • BS, Mathematics, Harvey Mudd College, 2004
