Kimberly McGuinness is an undergraduate Materials Science and Engineering student. She is currently working with Ph.D. student William Bowman on the development of a novel in-situ transmission electron microscope (TEM) holder, and the characterization of grain boundaries in solid oxide fuel cell (SOFC) electrolytes. Both projects contribute to a better understanding of nanoscale processes that dictate SOFC efficiency. Kimberly has assisted in the materials selection and preliminary materials testing for the TEM holder project. Her responsibilities for the grain boundary characterization project have included TEM sample preparation, data analysis and image processing. Kimberly joined the group in the winter of 2013. She is currently completing her work with the group as part of the Fulton Undergraduate Research Initiative.
