currently looking at the role of integrons in geneticexchange in soil and aquatic environments. I am interestedin the types of genes that can be exchanged via integrons,as well as the phylogenetic diversity of the organisms thatcontain integrons.Astrid E. J. OgilvieFellow of INSTAAR. PhD:1982, University of EastAnglia, Norwich, U.K.Specialty: The transcription,analysis, and calibration ofhistorical documentary climaterecords, in particularunpublished manuscriptsources, in Icelandic, Danish,Norwegian and Swedish.Research Interests: The environmental, social, andhuman history of countries bordering the North Atlanticregions, in particular Iceland, Greenland, Norway, and theUnited Kingdom; the past climate and sea-ice record ofIceland; human and social dynamics in the context of climaticand environmental changes.Scott D. PeckhamINSTAAR Fellow. PhD: 1995,University of Colorado atBoulder.Specialty: Surface waterhydrology, geomorphology,scaling analysis, and mathematicalmodeling.Research Interests:Physically based mathematicaland numerical modelingof watershed-scale hydrologic systems, source-to-sink sedimenttransport, scaling analysis, river networks, theoreticalgeomorphology, grid-based computational methods, efficientcomputer algorithms, and fluvial landscape evolutionmodels.W. Tad PfefferFellow of INSTAAR;Associate Professor of Civil,Environmental and ArchitecturalEngineering, Universityof Colorado at Boulder.PhD: 1987, University ofWashington.Specialty: Glaciology, continuummechanics, heattransfer.Research Interests: Dynamics of present and past glaciersand ice sheets, through field observational methods andnumerical modeling, with emphasis on analysis of stress,deformation and defracture, and iceberg calving and ice/ocean interaction. Also, heat and mass transfer in seasonaland perennial snowpacks and atmospheric and snowpacktemperature measurement methods.Tim R. SeastedtFellow of INSTAAR; Professorof Ecology and EvolutionaryBiology, University ofColorado at Boulder. PhD:1979, University of Georgia.Specialty: Terrestrial ecosystemsand biogeochemistry.Research Interests: Bioticinteractions with physicaland chemical properties ofthe environment to control patterns of energy flow andmaterial cycling. Emphasis is placed on soil phenomena,particularly those of grassland and tundra ecosystems.Robert F. StallardFellow of INSTAAR; ResearchHydrologist of the U.S.Geological Survey. PhD:1980, MIT-WHOI.Specialty: Biogeochemistry,hydrology, and geomorphology.Research Interests: Myprincipal interest is the earthsurfaceenvironment andhow it changes on human and geologic time scales.Currently, my focus is the study of climate and land-usechanges and how these affect processes that control thecomposition and dispersal of dissolved and solid phases inrivers and trace gases in the atmosphere.James P. M. SyvitskiFellow and Director ofINSTAAR; Professor ofGeological Sciences,University of Colorado atBoulder. PhD: 1978,University of BritishColumbia (1) GeologicalSciences, 1st class, (2)Oceanography, 1st Class.Specialty: Sedimentology,oceanography, hydrology, numerical modeling (climate-icewater-sedimentinteractions), marine geophysics, slopeinstabilities, seafloor acoustics.Research Interests: Presently investigating: (1) the dischargedynamics of global rivers and the sediment load theycarry, (2) the morphology and deposits of continental margins,(3) the impact of high-energy weather events on ourcoastline; and (4) the impact of ice sheets on high-latitudeshelves and slopes.46 | PEOPLE
Alan R. TownsendFellow and Associate Directorof INSTAAR; AssociateProfessor of Ecology andEvolutionary Biology,University of Colorado atBoulder. PhD: 1994, StanfordUniversity.Specialty: Biogeochemistry/ecosystem ecology.Research Interests: Carbonand nitrogen dynamics at regional to global scales; phosphoruscontrols over C and N in moist tropical systems;nutrient controls over soil carbon storage; human healtheffects of a changing N cycle.James W. C. WhiteFellow of INSTAAR; Professorof Geological Sciences,Director of the EnvironmentalStudies Program, Universityof Colorado at Boulder. PhD:1983, Columbia University.Specialty: Global change,paleoclimate dynamics, biogeochemistry.Research Interests: Stableisotope laboratory: global scale climate and environmentaldynamics, carbon dioxide concentrations and climate fromstable hydrogen isotopes peats and other organics, climatefrom deuterium excess and hydrogen isotopes in ice cores;isotopes in general circulation models; modern carbon cycledynamics via isotopes of carbon dioxide and methane.Mark W. WilliamsFellow of INSTAAR; Professorof Geography, University ofColorado at Boulder. PhD:1991, University of California,Santa Barbara.Specialty: Alpine biogeochemistry,hydrology, andsnow hydrology.Research Interests: Theprocesses that determine thehydrochemistry and biogeochemistry of high-elevationbasins including the storage and release of solutes from thesnowpack, biogeochemical modifications of snowpackrunoff, nutrient cycling, and hydrologic pathways and residencetime. Current projects include the Rocky Mountains,Ecuadorian and Bolivian Andes, and Central Asian areas ofKazakhstan, Kirghizia, and China.Connie A.WoodhouseINSTAAR Affiliate; AssociateProfessor, Department ofGeography & RegionalDevelopment, University ofArizona. PhD: 1996,University of Arizona.Specialty: Paleoclimatology,dendrochronology, climatology.Research Interests: Research has focused on the generationand interpretation of high-resolution records of climatefor the past 2000 years. Current research projects concerntree-ring reconstructions of drought for the Great Plains andRocky Mountains, as well as investigations into the mechanismsof long-term drought and impacts on ecosystems anddisturbance regimes. Other work addresses millennial-lengthreconstructions of temperature and atmospheric circulationfor the northern Rockies and western United States. Recentprojects target ways to generate dendrohydrologic reconstructionsthat are more useful to water resource managers.A group of INSTAAR Directoratemembers, March 2007.
