General Information

My primary current research investigates, from a geologic perspective, the paleoclimate and paleolandscape records of soils preserved as paleosols in the geologic record, using modern soil analogs where appropriate. I am also interested in applications of studies of surficial materials to solving environmental and hydrogeological problems. My collaborative research is being conducted with researchers at Baylor University, Murray State University, the University of Wisconsin-Madison, the University of Tennessee-Knoxville, Texas A&M University, and Rutgers University. I work actively with soil scientists, geochemists, stratigraphers and sedimentologists, physical geographers, and geoarchaeologists in these endeavors.

Research Projects

(1) measuring climate-dependent properties of modern Vertisols in order to interpret the paleoclimate record of Phanerozoic paleosols in the geologic record

(2) developing proxies and pedotransfer functions for modern soils in order to reconstruct colloidal properties of paleosols in the geologic record

(3) conducting climate and landscape reconstructions of wetland-floodplain-lake and lake-margin systems in the Miocene and the Pleistocene-Holocene of East Africa

(4) interpreting the late Pleistocene-Holocene climate record of Pleistocene-Holocene floodplain soils and paleosols, and speleothems in the middle Atlantic and southeastern US using stable isotopes of soil organic matter

(5) investigating the late Pleistocene-Holocene climate record of Central Alaska, using paleosols

(6) examining the role that pedogenic processes have in affecting the porosity and hydraulic conductivity of soil and fractured sedimentary and granitic saprolite

(7) interpreting the pedogenic signature of early terrestrial ecosystems recorded in Ptrecambrian paleosols in North America

(8) interpreting the genesis of pedogenic carbonate in modern soil systems and wetlands in order to calibrate the paleoclimate proxy used for paleosols in the geologic record

Photomicrographs showing examples of major dissolution (unconformity) surfaces identified in speleothem RM0710-2-1, arranged as pairs with UV fluorescence (UVf) and plane-polarized light (PPL). (A, B) Major surface at 102.5 mm depth, showing dissolved calcite crystals overlain by 0.5 mm thick terra rossa deposit containing Fe oxides, detrital limestone host rock fragments and reddish-orange reworked soil aggregates. (C, D) Major surface at 76.5 mm depth, with dissolved calcite crystals overlain by cloudy calcite containing detrital inclusions and inclined, bright UVf calcite-filled fractures. (E) Major surface at 40.75 mm depth, showing calcite crystal dissolution, overlain by very bright fluorescent calcite in which UV layers become more distinct upward in speleothem. (F) Details of terra rossa deposits mantling major surface at 50.5 mm depth, showing detrital calcite grains derived from host rock as well as reddish-orange reworked soil clasts. (G, H) Major surface at 15 mm depth, with dissolved calcite crystals overlain by perched, detrital silt-sized fragments of limestone host rock.
