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 some surface physics. 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. 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. Mark has worked closely with many IBM and visiting scientists on of these tools, and co-authored over 50 journal articles and several patent filings.
