    Summary

    I was a research scientist in academia and conducted multiple scientific projects. My research centered on agricultural ecology and evolution of invasive species with a focus on population biology of natural enemies in pest management. I contributed to several pest management programs, including biological control of soybean aphids and cereal leaf beetles. I also studied the interspecific interactions between predators - pest insects (prey) - plant systems, and ecology and evolution in introduced biological control agents, all of which were very important topics for the development of the sustainable pest management in agricultural systems. I regularly collaborated with researchers from the other fields and applied modern experimental and analytical tools. I wrote multiple successful grants and my research resulted in 16 peer-reviewed papers and 1 book chapter. I was actively involved in national and international academic societies, and I organized multiple symposia at national and international meetings.
