Research Interests
 
Arctic ecosystem ecology, including:
  • Trophic interactions that drive ecosystem carbon cycle processes
  • Biotic and abiotic drivers of community composition, above- and belowground productivity and ecosystem CO2 exchange processes
  • Above- and belowground plant phenology
  • Partitioning ecosystem respiration betweeen autotrophic and heterotrophic sources
  • Spatial patterns in plant phenology and CO2 flux
  • Plant water-use dynamics
