Waterloo, Ne

Trait Integration Corn Breeder. Developed Hawaii winter nursery facility on Molakai, managed all trait integration breeding, new trait genetics testing, and developed a new trait integration/conversion process that enabled us to prioritize and deliver traited hybrids to market faster than ever before.

Johnston, Ia

Insect Resistance Trait Development. Selected events for Herculex I and Herculex RW market; developed the combined process of event sorting, initial trait integration, and regulatory seed production that was then used as a model for other traits in the Pioneer pipeline; team member that brought Herculex I (cry1F) to market.

Johnston, Ia

Plant Molecular Biology. Team member that developed the corn EST library database; projects with identification and cloning of corn root-specific promoters, corn wound response, and with development of a Bacillus protein expression system.

Oxford, Nc

Plant Molecular Biology. Isolated and cloned a root-specific and nitrate-inducible Ferredoxin NADP+ Reductase gene from corn.

West Lafayette, In

Corn Transformation Development Technology. Developed Agrobacterium-based corn and rice transformation systems and tissue culture methods. First to confirm stable transfer of genes from Agrobacterium to corn tissue.

Lubbock, Tx

Wheat stress physiology. Developed growth chamber methods for measuring photosynthetic water use efficiency, compared water stress response in wheat varieties that differ in yield under water stress.
