Morphology and Genetics of Ambrosia
My current research interests are in using molecular techniques to study changes in populations over time. My research has so far focused on wind-pollination and population dynamics of ragweed (genus Ambrosia).

In Fall 2006, I completed a two month field experiment in Upper Marlboro, MD designed to study the effects of ragweed floral morphology and pollen clustering on the atmospheric dispersal of pollen. From April to September 2008, I worked in the Environmental Fluid Mechanics group at EPFL in Lausanne, Switzerland helping with a large campaign to measure methane, water vapor, and nitrous oxide flux from a lake environment.

I am currently a Research Student at the Smithsonian Institute Laboratories of Analytical Biology. There I am working with Dr. Elizabeth Zimmer on a project that will characterize recent changes in North American Ambrosia artemisiifolia populations through molecular analysis of of modern specimens and ancient DNA preserved in historical seeds, pollen, and leaf tissue. My final project will be a detailed survey of ragweed floral morphology.
