Phone: +41 1 724 8468
Effective until April 2003

Tom Albrecht received a B.A. in physics from Carleton College in 1985 and a Ph.D. in applied physics from Stanford University in 1989. His thesis research at Stanford focused on Atomic Force Microscopy (AFM), and included the first demonstration of atomic resolution imaging on electrically nonconducting samples, and the development of microfabricated force-sensing cantilever probes, which are used routinely in AFM today. After completion of graduate school, he worked briefly for Park Scientific Instruments (PSI), helping launch PSI's first AFM product.

Since late 1989, Tom has been a research staff member and manager at the IBM Almaden Research Center in San Jose, CA. At IBM, his work has centered primarily on technologies for tape and disk drives. In tape technology, he contributed to a novel track-following servo technology, referred to as "Timing-Based Servo," which allows higher track density and higher reliability. This technology, along with various mechanical designs of his, has been implemented in IBM's 3570 Magstar MP family of tape products, and has become the standard servo technology for the newly launched Linear Tape Open (LTO) tape platform adopted by Hewlett-Packard, IBM, Seagate, and other companies.

For disk drives, Tom spearheaded the development of ramp load/unload technology for IBM's Travelstar mobile disk drives. Load/unload technology provides increased data density, reduced power consumption, better shock robustness, and improved reliability over conventional contact start-stop technology commonly used in disk drives. Another recent project has been design and applications work for IBM's "Microdrive" 1-inch disk drive. The Microdrive is the world's smallest, lightest disk drive intended for new markets such as digital cameras, MP3 music players, and handheld computers.

Tom has 42 issued U.S. patents and 33 publications. He served on the LTO tape standards committee, and represented IBM in the CompactFlash Association to modify the CompactFlash standard to accommodate IBM's microdrive. He is a member of the IBM Academy of Technology.

  • The summer student research experience - They appear at your door in early Summer and remind you about your generous offer to mentor last Fall (G, S)
  • Extreme physics in high magnetic fields – Tricks with superconductors, explosives, and atoms with lots of f-electrons to get really high "B" (P, G, S)

Prof. Brooks has worked in many areas of experimental low temperature and high magnetic field physics. His early work at and involved the properties of superfluid helium, first in bulk liquid, and in restricted geometries and thin films. Upon joining the faculty at Boston University, he took advantage of the facilities at the Francis Bitter National High Magnetic Field Laboratory to develop very low temperature experimental capabilities in high magnetic fields. This opened new opportunities for the investigation for novel condensed matter systems – quantum fluids, organic conductors and superconductors, doped semiconductors, the quantum and fractional quantum Hall effects, and heavy Fermion systems – at temperatures below 0.1 K and in magnetic fields above 30 T. Brooks joined the faculty at Florida State University when the National High Magnetic Field Laboratory was established, and has since continued his high magnetic field research, which is presently funded by the National Science Foundation. International collaborations with Asian, Australian, and European research teams are a major component of his program. In his studies of low dimensional magnetic and superconducting materials, he has gone to the extremes of high magnetic fields in explosive magnetic flux compression experiments (800 tesla), and presently holds the record for doing an experiment in the largest steady state magnetic field at 47.8 tesla. He has also carried out magnetic levitation experiments, including the "floating frog" demonstration. Brooks has a keen interest and dedication to K-12 and other outreach and research experience programs, where every summer his group expands to include teachers and students at all levels in his laboratory activities. Brooks is presently teaching an honors level introductory astronomy class in the Physics Department at Florida State.

  • The Physics of the Actin Cytoskeleton (S)

Josef Käs is an assistant professor of physics at the Center for Nonlinear Dynamics and the Institute for Cellular and Molecular Biology at the University of Texas at Austin. He received his Ph.D. from the Technische Universität München. His research involves the next big challenge for physics: studies of soft condensed matter physics on the scale of nanometers to tens of microns, i.e., on the scale of proteins and cells, in complex biological matter-often far from equilibrium and frequently behaving in a highly nonlinear manner. "There has been tremendous progress in molecular biology," Käs says. "Nevertheless, many of the questions addressed by molecular biology can only be understood by developing a novel combination of nanosciences and soft condensed matter physics." He says one of the most appealing aspects of this synergetic research in physics, chemistry and biology is that it simultaneously advances fundamental science and provides novel applications in biomedicine and materials sciences.

  • Falling Cats and Classical Quarks (P, G, S)
  • Figure Eights with Three Bodies (P, G, S)
  • Heisenberg and the Isoperimetric Inequality (P, G, S)

Richard Montgomery is a professor of mathematics at the University of California at Santa Cruz. He received his B.A. at Sonoma State University and his Ph.D. at the University of California at Berkeley. His work can be characterized as applied differential geometry. Much of it involves applications of gauge theory (fiber bundles with connections) to problems in mechanics and control theory. One such problem is that of a falling cat dropped from upside down. This geometric point of view on the cat's problem gives us a deep understanding and allows us to solve it explicitly for certain model cats. Most recently, Montgomery has returned to the N-body problem, which has a long history. He has been approaching it using modern methods taken from equivariant differential geometry and calculus of variations. Recently Montgomery and Alain Chenciner rediscoverd and proved the existence of a figure eight orbit type orbit for three bodies. The three masses chase each other around a figure eight shaped planar curve. This received press in Science, Science News and several other popular science journals.

After a year's appointment as Assistant Professor at Trent University, she joined the Department of Anthropology at McMaster University in 1975. She was promoted to the rank of Professor in 1983, and became Chairman of the Department of Anthropology in 1985. In 1989 Dr. Szathmáry left McMaster to be Dean of the Faculty of Social Science at the University of Western Ontario, and she returned to McMaster University in 1994 to serve as Provost and Vice-President (Academic). In 1996, she was named President of The University of Manitoba.

Since her arrival in Manitoba, Dr. Szathmáry has been actively involved in a number of public and private committees and boards at provincial and national levels. In 1998 she was a member of the Manitoba Electoral Boundaries Commission. As well, she was Co-Chair of the Manitoba Diabetes Strategy Steering Committee (1997-99), currently Co-Chairs the Advisory Committee on Diabetes to the Minister of Health and is a member of the board of the St. Boniface General Hospital. In 2000 she became Chair of the Council of Presidents of Universities in Manitoba and was elected a member of the Executive Committee and Board of the Association of Universities and Colleges of Canada.

Dr. Szathmáry's research has focused on the genetics of the aboriginal peoples of North America. Her work has addressed the causes of type-2 diabetes in aboriginal North Americans, the genetic relationships within and between peoples of North America and Asia, and microevolution of the peoples of the subarctic and arctic. Her field research was conducted among Ottawa, Ojibwa and Dogrib peoples in Ontario and the Northwest Territories. She is the author of over 80 scientific articles and reviews, and has co-edited three books. Dr. Szathmáry is the past editor of the Yearbook of Physical Anthropology (1987-91), and of the American Journal of Physical Anthropology (1995-2001), which is the official publication of the American Association of Physical Anthropologists.

Dr. Szathmáry is a Fellow of the Arctic Institute of North American (1989) and the American Association for the Advancement of Science (1995). She held the Paul T. Baker Lectureship at The Pennsylvania State University in 1992, and was named a life member of the Canadian Association for Physical Anthropology in 1997.

  • Human Origins:  Newest Evidence of Our Earliest Ancestors (P, G)
  • How Human Intelligence Evolved (G.S)
  • The Origin of Human Locomotion (P,G.S)

With a dual faculty appointment, Carol Ward serves as the primary link between anthropology and anatomy at the University of Missouri-Columbia.  Her interests include the evolution of humans and our closest relatives, apes and monkeys, and her research focuses on fossils from East and South Africa, primarily Kenya. She takes a mechanical approach to the interpretation of the postcranial skeleton and uses these principles to reconstruct the behavior of extinct animals.

Her current research involves description and interpretation of early hominid fossils from Ethiopia.  Another interest is the great radiation of apes that lived in the early Miocene (almost 18 million years ago) out of which came human ancestors.  Ward is also interested in the functional anatomy of the spines and the hands of modern and fossil humans and of our earlier relatives.  She teaches anthropology courses during winter semester only, and anatomy during summer.
