Root Biology Lab at
The Morton Arboretum

Postdoc Opportunity

Check out this opportunity to work with Dan Ricciuto and Colleen Iversen at Oak Ridge National Laboratory. The position is focused on improving the representation of roots and root-processes in models and leverages long-term datasets of root growth from our work at The Morton Arboretum.  

The Landscape Below Ground

Gary Watson organized the Landscape Below Ground IV conference which was held in Lisle, IL, USA in the fall of 2018. The proceedings from the "LBG IV" is now available through the International Society of Arboriculture.  Keep your eyes and ears open, LBG V may be just around the corner.
