Research Interests

My doctoral research is centered in the realm of plant insect coevolution. I am interested in plant-herbivore interactions, mainly in the uptake and use of plant toxins by phytophagous insects (i.e. sequestration) as a defense to ward off predators. I will investigate the mechanisms underlying sequestration of cardiac glycosides (cardenolides) in milkweed bugs (Lygaeinae). During my PhD, I will try to understand the mechanisms and the evolution of these physiological processes by using various methods, including feeding assays and chemical analyses. In brief, I will integrate my mechanistic findings into the conceptual framework of insect plant coevolution. The ultimate goal of my research is to understand how the interplay of resistance and sequestration directs coevolutionary interactions between plants, insects, and their predators.
