  • Research Interests:

    My research uses molecular techniques to address applied agricultural and ecological problems, especially invasive plant species. I also work on evolution of introduced species, using population genetics methods. I have experience in agricultural and social interactions surrounding GE crops, as well as biological questions related to systematics and conservation of plant- and animals species.

    Dr. Ania Wieczorek’s work has two areas of focus, the Molecular Ecology Lab concentrates on conservation and the management of invasive species through the application of DNA technology and the Biotechnology Outreach Program, which provides public education about agricultural biotechnology to a wide range of audiences and includes the Gene-ius Day Program

    Dr. Ania Wieczorek's research interests are broad and include addressing agricultural problems (such as invasive species management and risk assessment for genetically modified crops), environmental conservation, population genetics, and evolutionary biology. I address issues in these areas by molecular biology technology. She also has a strong interest in using molecular techniques to address basic and applied ecological problems and my research work includes both aspects, viz., problems of agricultural importance, combined with a basic study of the population genetics of groups of important invasive plants.

    In addition to this, Dr. Ania Wieczorek is the director of the Biotechnology Outreach Program. As she worked with adults and children in the community she recognized the need for the increased knowledge and awareness of genetics. This is important to her because with this knowledge, individuals are better able to understand and make decisions about biotechnology issues.
