I joined the Geosciences Department at UMass in January, 2001 after 11 years at the University of Bern in Switzerland. I was an undergrad at Rice University, and went on to do an M.S. at the University of North Carolina studying carbonate sedimentology and a Ph.D. at Duke University on dolomite geochemistry.

My research interests are broad, but mostly fall into two areas: paleoclimatology and sediment diagenesis. In both of these I use stable isotopes as a research tool. Over the past several years, my research has focused on developing records of climate change on the continents. While the broad outline of climate variation over the past several million years is fairly well known, the causes of climate change on various time scales are not. Also, climate on the continents is much more spatially variable than in the oceans. Thus, my research is aimed at producing quantitative estimates of climate change from continental areas at high enough resolution to be able to determine the driving forces behind climate change at various time scales.

One of the main archives of climate information that I am interested in is speleothems, the family name for cave deposits such as stalagmites and stalactites. Speleothems faithfully record changes in the climate signal contained in O and H isotope ratios of rainfall. I like to think of them as underground ice cores. In Oman and Yemen, we have produced records of changes in precipitation that extend back over several hundred thousand years. For the most recent climate period, the Holocene, these records are up to annual in resolution. I have also used isotopic analyses of planktonic foraminifers, lacustrine sediments and the organic matter in peat bogs to develop climate records in South America and Europe.

My other main research area is investigating the chemical and mineralogical changes that occur in sediments along the way to becoming rocks. In particular, how and when and why massive dolomite forms has long been of interest to me. In January and February, 2001 I sailed on ODP Leg 194 as an inorganic geochemist. The ship drilled into two Miocene, dolomitized carbonate platforms on the Marion Plateau, which is just outside of the Great Barrier Reef National Park, Australia. I will be studying the geochemistry of carbonates and pore fluids recovered from these platforms hoping to find clues to the processes that led to dolomitization.
