Andrea Bruder received her Diploma in Mathematics at the University of Technology in Munich, Germany, and earned her Ph.D. in Mathematics at Baylor University.
Fields: Differential Equations, Applied Mathematics
My research interests are in the theory of differential equations and their applications in mathematical biology. Most recently, I have worked with David Brown in CC's math/computer science department and Miro Kummel in CC's environmental program on modeling an insect predator-prey system. This field system consists of ladybugs (Coccinella septempunctata, Hippodamia convergens) and aphids (Aphis helianthi), which are patchily distributed on racemes of yucca plants (Yucca glauca) in the Rocky Mountains of Colorado. The 107 patches are connected by the relatively fast dispersal of the ladybugs, whereas the aphids are relatively sessile. In a 30-day field study we observed a split of the aphid population sizes into extremely large and extremely small populations, a phenomenon known as spatial self-organization or pattern formation. In order to study the effects of density independent predator and prey immigration into the system and migration due to the predator's attraction to predation, work in progress includes the study of a two-patch, ordinary differential equations model, which is continuous in time and discrete in space (with David Brown and Miro Kummel).
