Biographical Sketch

Kara Beauchamp, W.F. Johnston Professor of Physics and Engineering, has been teaching at Cornell College since 2001.  Kara is fascinated by the role of quantum mechanics in the electronic and magnetic properties of materials, as well as the interaction of light with atoms and molecules.  As a life-long learner, she continues to explore new areas of research and is currently focusing on properties of plasmas in the regions of space surrounding newly formed stars. Kara teaches Astronomy, Introductory and General Physics, Lab Physics, Modern Physics, and other upper-level physics courses. She has studied high-temperature superconductors, low-dimensional magnetic materials, wind energy production, and dye-sensitized solar cells.  She regularly collaborates with students during summer research, most recently on astronomical plasmas, and previously on dye-sensitized organic solar cells. Ph.D. in physics, University of Minnesota.

Faculty-Student Research

Working with collaborators at the University of Iowa, Kara and her students have been studying the impact of assumptions about the shape of the Rosette Nebula on the values of electron density that can be extracted from radio wave data. Electron density is an important characteristic of a plasma surrounding newly formed stars (H II regions), and more well-known values can contribute to a deeper understanding of magnetic field strength in the galaxy.
