Elizabeth A. Grabau

Professor

Program Focus

The overall goal of my research is crop improvement in legumes, particularly soybeans and peanuts. My laboratory uses tissue culture and biotechnology approaches to improving nutrient (phosphorus) availability in soybeans and fungal disease resistance in peanuts.

Current Projects

Navigating the bioregulatory process for the approval of Blight Blocker peanuts engineered for resistance to Sclerotinia blight.
