Research Contribution

Research in the Jasieniuk lab focuses on two study systems: cropland weeds evolving resistance to herbicides and invasive plants with horticultural origins. The two systems are not only ideal for basic research on processes underlying weed evolution and spread, they include some of the worst weed problems in California. Thus, our research also contributes to improving the management of economically and environmentally significant plant pests in the state.

Research Interests

Population genetics and evolution of agricultural weeds and invasive plants

The Jasieniuk lab studies the population genetics, molecular ecology, and evolution of agricultural weeds and invasive plants. Our research focuses on elucidating the genetic, demographic, and evolutionary processes underlying the introduction, establishment, and spread of weeds and invasive plants, and their adaptation to changing environments, including management practices.
