Determining the consequences of the implementation of genetically modified (GM) crops into agriculture has been one focus in my research. I have studied the effects of hybridization and transgene movement from GM crops to their wild relatives using a Brassica model system. Future research will expand on current work and explore the consequences of crop gene introgression into the genetic backgrounds of weed species.

The enabling tool in my research has been the use of green fluorescent protein (GFP) as a marker for fitness enhancing transgenes, such as the Bt insecticidal protein. I am continuing my interest in the expression of transgene marker technologies, and am currently involved in the development of the transgenic systems for educational purposes. The use of novel GFP transgenic Arabidopsis in college-level genetics laboratory exercises allows students to explore Mendelian genetics and biotechnology in a single semester-long project.
