Martha R. (Molly) McCartney received a B.S. degree from The Evergreen State College, Olympia, WA, in 1982 and the Ph.D. degree in physics from Arizona State University (ASU), Tempe, in 1989. She is currently Professor in the Physics Department. Her research has been in the development and applications of off-axis electron holography for the measurement of nanoscale electrostatic and magnetic fields. This technique is an electron-microscope-based interference technique that provides unique access to the phase of a scattered electron wave. The technique has been shown to enable visualization and quantification of electrostatic and magnetic fields with very high spatial resolution and sensitivity, enabling unique insights into nanoscale physical phenomena. She was the awarded the 2009 Ernst Ruska Preis by the German Microscopy Society for her work on holographic imaging of magnetic materials and was given the 2011 Arizona State University Faculty Achievement Award for excellence in Defining Edge Research in Natural Sciences.
