1100 North University Avenue
Ann Arbor, MI 48109-1005
Phone: 734-764-0597 

Philip A. Meyers is an organic geochemist who is interested in the processes that are involved in the origin, delivery, and accumulation of organic matter in sediments and the evidence for paleoenvironmental changes that are recorded in the composition of sedimentary organic matter. His research focuses on paleoenvironmental reconstructions based on organic matter in Cretaceous black shales, Mediterranean sapropels, and Holocene lake sediments. The unifying element of his studies of marine and lake records is that both types of systems are sensitive to global climate change, although in ways that are differently influenced by local or regional factors. The marine records generally yield information about large-scale processes, whereas the lake records respond more rapidly to shorter-term phenomena. These various processes impact the production, delivery, and preservation of organic matter in the bottom sediments, which provides information that can be interpreted to yield histories of paleoenvironmental changes.

Use of multiple geochemical and sedimentary proxies is a distinctive feature of his approach to reconstructing paleoenvironmental histories. From his early research using bulk organic matter properties and lipid biomarkers, he has added organic carbon and nitrogen stable isotope compositions, Rock-Eval pyrolysis, and redox-sensitive trace metals to the suite of proxies he routinely uses. Active collaboration with other organic geochemists has broadened the range of organic geochemical proxies he finds useful to include hydrogen isotope values and compound-specific carbon isotope analyses for specific projects. He also works closely with marine micropaleontologists to integrate microfossil and organic geochemical evidence of paleoenvironmental conditions. An interesting aspect of his paleoreconstruction research is that his findings have relevance to estimating the future consequences of modern processes, such as human activities and climate change.

  • Sardinia in the Mediterranean (P,G,S)

Robert H. Tykot, Professor of Anthropology at the University of South Florida, received a BS in Archaeology and Chemistry (1983) and an MA in Classical Archaeology from Tufts University, and an MA (1993) and PhD (1995) in Anthropology from Harvard University. His research emphasizes scientific analysis of archaeological materials, especially elemental and isotopic studies, to investigate trade, technology, and dietary patterns in many parts of the world, including Algeria, Argentina, Belize, Bolivia, Chile, China, Cyprus, Ecuador, Egypt, France, Greece, Guatemala, India, Italy, Malaysia, Mexico, Peru, Romania, Tunisia, Turkey, South Africa, Sweden and the United States.

For 25 years, he has worked on obsidian in the central Mediterranean, including a recent survey and analysis of the obsidian sources on Sardinia, Lipari, Palmarola and Pantelleria and of artifacts found at Neolithic archaeological sites throughout the region. Professor Tykot has also conducted excavations at a Bronze Age site in Sardinia where a metal workshop was discovered, and a survey and excavation at Sennixeddu in Sardinia, a large obsidian quarry and workshop area. At the same time, his expertise in isotopic analysis of skeletal remains led to studies of fishing practices in coastal Italy, and of maize agriculture in New World societies. These projects have included analyses of South American mummies to look at seasonal variation in diets; differences based on social status in Mesoamerica; and the importance of marine resources in Florida.

Professor Tykot is the author or coauthor of more than 100 books, articles, and other scholarly publications, and has given more than 50 public lectures. He is a board member or reviewer for many scientific journals and grant agencies, and is an active member in more than a dozen national and international societies and organizations.

Roger White is University Research Professor in the Department of Geography, Memorial University of Newfoundland, St. John's, Canada, and since 1990 has also been Visiting Professor and Senior Scientist with the Research Institute for Knowledge Systems in Maastricht, The Netherlands. He received his PhD in geography from the University of North Carolina Chapel Hill in 1972, and taught at the University of Western Ontario before moving to Memorial in 1977. He has been visiting professor at several universities in Europe and North America, and has worked as a consultant at Los Alamos National Laboratory and as an invited researcher at the Santa Fe Institute. He has lectured widely in North and South America, Europe, and Australia. His research involves the use of algorithmic techniques like difference equations, cellular automata and agent based modeling to understand the structure, functioning, and evolution of geographical systems. Initially the focus was on cities and urban centered regions, and produced models with immediate relevance to problems such as traffic flow and urban sprawl. However, more recently the emphasis has shifted to integrated models of human-natural systems in which the geographical model provides a platform for linking other models of human systems, such as economic and demographic models, to models of natural systems in order to understand the functioning of the entire system as an integrated dynamic whole. This work underlies a developing theory of cities and regions as self-organizing, complex adaptive systems. It is also the basis of new software being developed to aid integrated planning of cities and regions, with trials currently underway in several countries. The work is also driving innovations in validation techniques for theories of complex, far-from-equilibrium systems.

Michael Wolf received his B.S. in Mathematics and Philosophy from Yale in 1981 before earning his Ph.D. at Stanford in 1986. After a term as a Moore Instructor of Mathematics at M.I.T., he moved in 1988 to Rice University where he is now Professor and Chair of the Mathematics Department. His research is in the geometry of surfaces, especially surfaces which are optimal in some way. In particular, one of his interests is the classical subject of minimal surfaces - mathematical versions of soap films -- which despite theory and examples stretching back through the centuries to Euler, is an active field of contemporary mathematics. In this area, Wolf and his co-authors have found several new examples with some surprising properties while ruling out other types of films. He was a Sloan Research Fellow in 1991-3, and is presently on the editorial boards of the Journal of Geometric Analysis and the Bulletin of the American Mathematical Society.
