My research work is based on the conceptual framework of plant-insect coevolution. In brief, I am interested in plant-herbivore interactions, mainly in the uptake and use of plant toxins by herbivorous insects (i.e. sequestration). Specifically, I investigate the mechanisms underlying sequestration of cardiac glycosides (cardenolides) in milkweed bugs (Lygaeinae). During my doctoral research, I try to understand the mechanisms and the evolution of these physiological processes by using various methods, including feeding assays, biochemical assays, and analytical techniques.
