He served on the Science Advisory Board of the Data Storage Institute in Singapore and on the boards of Silicon Graphics, Zilog, STMicroelectronics, Read-Rite and Ontrack Data.

 

 

Manager for Nanomagnetics Facility: Dr. Robert J. Wilson

As the Manager of the Nanomagnetics Facility, Dr. Robert Wilson leads the daily operation of the Facility and interacts with the graduate students and postdoctoral fellows regularly. He also directly participates in the research projects on magnetic nanopartices, nanoimprinting, biosensing, and biochips.

Dr. Robert Wilson is a Senior Research Associate in the Department of Materials Science & Engineering at Stanford University. His current research focuses on magneto-nano sensors and the use of nanoimprint lithography based fabrication for the creation and chemical functionalization of nanostructures and nanoparticles made from a variety of materials, including multilayer magnetic films. Dr. Wilson has been involved in nanotechnology research since his pioneering efforts at IBM Research used Scanning Tunneling Microscopy to first reveal the atomic corrugation and structure of close packed metal surfaces and the internal structure of individual molecules. He has also contributed and retains interests in diverse areas including magnetic resonance, positron annihilation, various microscopies, surface analysis methods, and thin film deposition and patterning techniques. Dr. Wilson has published over 60 papers, holds 9 issued patents, and received many IBM awards for his research and patents. Dr. Wilson received his B.S. and Ph.D. in physics from UC Berkeley in 1972 and 1982, respectively, and his M.S. in physics from University of Chicago in 1974.

 

 

Professor Bruce M. Clemens

      Dr. Clemens leads a group of around 12 researchers working on the synthesis, structure, and properties of thin film and nanostructured materials. He uses the flexibility of physical vapor deposition to engineer materials on the atomic scale. He and his group study epitaxial thin films, multi-layers and nanostructured materials where the structure and properties are strongly influenced by the small size and the presence of interfaces. They investigate the structure and its correlation with growth process and properties including stress, chemical kinetics, phase stability, magnetotransport, mechanical properties and electronic and optical properties. His group is working on new materials and processes for electronic applications, for photovoltaic devices and for tuning thermodynamics and kinetics for hydrogen and chemical energy storage. He teaches classes in nanomaterials synthesis, x-ray diffraction, solid-state physics, sustainable energy, solar cells, and batteries. Bruce Clemens is the author of over 200 scientific papers and 2 patents. He serves on the technical advisory boards and as consultant for companies that span the range from large multinationals to small start-ups. He holds the Walter B. Reinhold Professorship in the Stanford School of Engineering and is the 2012 President of the Materials Research Society.

Professor Bob Sinclair

        Dr. Sinclair received his B.S. and Ph.D. degrees in Materials Science from Cambridge University. After holding research positions at the University of Newcastle-upon-Tyne and the University of California, Berkeley, he joined the faculty of Stanford University, Department of Materials Science and Engineering, in 1977. He has been directing Stanford Nanocharacterization Lab since 2000. He  became the Chair of the Department of Materials Science and Engineering in 2004.
      Dr. Sinclair's research centers on the application of high resolution transmission electron spectroscopy (TEM) to a wide range of materials problems. TEM provides imaging of materials at the atomic level, and therefore provides microstructural information necessary for the understanding of structural, electrical, and magnetic properties of materials. Dr. Sinclair's research has included materials of interest both to microelectronics and to magnetic data storage.
      Dr. Sinclair has received a number of prestigious awards for his research, including; The Robert Lansing Hardy Gold Medal of the Metallurgical Society of the AIME, the Eli Franklin Burton Award of the Electron Microscopy Society of America, an Alfred P. Sloan Fellowship, and the Marcus E. Grossman Award of the American Society for Metals. He has also received an award for Excellence in Undergraduate Teaching at Stanford. He is very active in several professional societies and in the organization of symposia and workshops on electron microscopy.

Professor Kam Moler

       Dr.  Moler received her B. S. in 1988 and her Ph.D. in 1995, both from Stanford University.  She then performed her postdoctoral research at Princeton and at IBM, Yorktown Heights. She joined the Applied Physics Department as an Assistant Professor in fall 1998. Now she is an associate professor in applied physics and physics, and directs the NSF Center for Probing at Nanoscale.

       Prof. Moler received the Stanford Centennial Teaching Award in 1990 and the Kirkpatrick Award for excellence in teaching in 1992. She received a prestigious R. H. Dicke postdoctoral fellowship in 1995. As a faculty member she received a Frederick E. Terman Fellowship, an Alfred P. Sloan Fellowhship, an NSF CAREER award, a William L. McMillan Award (1999), and a Presidential Early Career Award for Scientists and Engineers.

        Dr. Moler's research interests include local magnetic probes for nanoscale studies, microscopy and Imaging, physics of nanostructured materials, superconductivity, and experimental condensed matter.

  Professor Joachim Stohr

         Dr. Stohr received his B.S. in Physics from Friedrich Wilhelms University in Bonn, his M.S. in Physics from Washington State University (as a Fulbright scholar) and his Ph.D. in Physics from the Technical University of Munich. After receiving his Ph.D. he spent a year as a post-doctoral fellow at Berkeley at their synchrotron radiation laboratory (ALS). Dr. Stohr joined the technical staff of IBM's Almaden Research Center in 1985 and was a Consulting Professor of Electrical Engineering at Stanford University. He joined Stanford as a full professor and Deputy Director of Stanford Synchrotron Radiation Lab in 2000. He is a fellow of American Physical Society.

       Dr. Stohr's research has focused on the development of novel investigative techniques based on synchrotron radiation for exploring the structure and properties of surfaces and thin films. He played a major role in developing surface extended x-ray absorption fine structure (SEXAFS) as a tool for exploring surface structures, especially for adsorbate geometrics on surfaces. He then developed near edge x-ray absorption fine structure (NEXAFS) as a technique for the study of simple and complex molecules bonded to surfaces and for the study of thin organic (polymeric) films. These two techniques have become widely used, and Dr. Stohr has written definitive reviews of both fields.

        More recently Dr. Stohr has turned his attention to the use of x-ray magnetic circular dichroism (XMCD) and photoelectron emission microscopy (PEEM) in magnetic materials. XMCD allows element-specific measurement of magnetic moments, and can resolve these moments into spin- and orbit-derived moments. This technique also is capable of measuring the separate geometric components of magnetic moment. XMCD has been used to establish the degree of magnetic polarization of non-magnetic spacer metals in magnetic multilayers and, by measuring the components of orbital angular momentum, to illuminate the origins of interfacial magnetic anisotropy. His group has used PEEM to image exchange bias at the interface and current-driven spin switching.
