research overview

  • As a Research Associate in the Department of Ecology & Evolutionary Biology I am interested in the mechanisms of herbivore-induced responses in several different plant species including wild tomato and tobacco, milkweed, and goldenrod. Specific projects I am working on require qualitative and quantitative analyses of morphological, biochemical, and molecular plant traits. I am developing tools and analytical methods for the characterization of these traits and test their function in the interaction of the plant with its natural arthropod community including herbivores, natural enemies and pollinators, in field and laboratory experiments. In the lab of Andre Kessler I am working on two major research projects: 1) The herbivore-specific induction of changes in primary metabolism in wild tobacco (Nicotiana attenuata). 2) Herbivore-induced pollinator limitation and the evolution of defense vs pollination strategies in wild tomato plants.
