When William Rippard, a Ph.D. candidate in applied physics at Cornell, was invited to speak at the American Physical Society meeting in Minneapolis in March, it was only the latest in a string of honors that this young researcher has been receiving of late.
Last November he was named the winner of the 1999 best student presentation award at the 44th Magnetism and Magnetic Material Conference in San Jose, Calif. The award was given for Rippard's oral presentation "Ballistic Electron Magnetic Microscopy: Imaging Magnetic Domains with Nanometer Resolution."
The conference is sponsored by the American Institute of Physics and the Magnetics Society of the Institute of Electrical and Electronics Engineers, in cooperation with the Office of Naval Research, the American Physical Society, the American Society for Testing and Materials and the American Ceramic Society.
Only a month previously he had been presented with the Leo Falicov Best Student Paper Award -- also for an oral presentation on ballistic electron magnetic microscopy -- at the 46th international symposium of the American Vacuum Society (AVS) in Seattle. He is an invited speaker at the next AVS meeting in October.
Rippard, who is studying under Robert Buhrman, the J.E. Sweet Professor of Applied and Engineering Physics, is a 1998 Cornell graduate (M.S., applied physics) and a 1994 graduate of the University of Florida, Gainesville (B.S. double major, mathematics and physics with honors).
He and Buhrman have been joint authors of several research papers.
Since 1995 Rippard has been investigating current transport in thin films.
