About Me

Picture
Welcome! I am a current NSF Postdoctoral Fellow and have dedicated my research to understanding how free-living nematode communities infer ecosystem functioning.

Current Broad Interests

Picture
Nematode community analyses to indicate shifts in soil food web function 
Picture
Regenerative agriculture practices
Picture
Microcosm experiments to address ecosystem mechanisms 

Current Work

  • Understanding how nematode communities shift over temporal periods under varying land-use 
  • Effects of climatic disturbance on soil food web function
  • Variation of nematode species function on nitrogen cycling
  • Investigating nematode- microbial interactions
