Research interests and expertise:

The Sustainable Agroecosystem Group is an international multidisciplinary group committed to playing a role in bringing healthy food from fields to tables around the world for generations to come. We strive to do this while fostering a healthy environment that can be enjoyed by young and old for centuries to come.

We are trying to add our modest contribution to this enormous task by effectively integrating experimental work with modeling to cover space and time from the micro- to global and daily to century scales. We focus on the farm and decadal scale because it is at these scales that decisions are being made.

Within this broad subject we focus on how carbon and nitrogen cycling is affected by management and driven by the interactions between plants, soil structure, and soil biota.

Prizes, Awards, Honors:

  • UC Davis Chancellor's Fellows, 2011-2016
  • AAAS Fellow, 2010
