Mark Reuter is an Advisory Engineer at IBM’s T. J. Watson Research Center, providing support and development in the Nanoscale Materials Analysis Department, and more recently in the MRAM department. He received a Ph.D. in physics studying fluid mechanics at Lehigh University in 1984, and was a postdoc, also at Lehigh, learning vacuum technology and surface physics doing high resolution electron energy loss spectroscopy. In 1986 he joined IBM and has been there since. After some years working with a Medium Energy Ion Scattering system, he then helped design and build IBM’s first Low Energy Electron Microscope (LEEM), and to build and sell two additional clones. Meanwhile IBM acquired an Hitachi H9000 UHV-TEM, which he spent several years modifying and upgrading. In 2004 he recieved the Outstanding Technologist Award from the Microscopy Society of America. After that he worked on assembling a dual beam FIB/SEM four probe low temperature STM. Later he joined MRAM helping to maintain and operate sputter deposition tools. In 2017 he received the George T. Hanyo Award from the American Vacuum Society. Mark has worked closely with many IBM'ers, visiting scientists, post-doc's and students, and co-authored over 50 journal articles and several patent filings.
