Biography
I am a geochemist and geologist specializing in lakes, wetlands, and soils, with a focus on carbonates. I am particularly interested in what stable isotopes in carbonates can say about changes in past environmental conditions in these types of environments. My main research goal is to understand how changing environmental conditions affect water availability in arid regions. I have done research in Tibet, the Andes, and the western United States. My current research is focused in the US Great Basin, Alaska, and the southern Rocky Mountains.

Status: Active Denver Radiogenic Isotope Lab
Radiogenic isotopes are daughter nuclides derived from natural decay of radioactive parent nuclides. They are useful for determining radiometric ages of rocks, minerals, and soils, and can be used as natural tracers of lithologic, hydrologic, and biologic materials. GEC scientists are currently focused on radiometric dating by U-Pb, U-Th, Sm-Nd, and Rb-Sr, as well as tracer studies using...

North-south dipole in winter hydroclimate in the western United States during the last deglaciation
During the termination of the last glacial period the western U.S. experienced exceptionally wet conditions, driven by changes in location and strength of the mid-latitude winter storm track. The distribution of modern winter precipitation is frequently characterized by a north-south wet/dry dipole pattern, controlled by interaction of the storm...

Establishing chronologies for alluvial-fan sequences with analysis of high-resolution topographic data: San Luis Valley, Colorado, USA
On active alluvial fans, debris-flow deposits and frequent avulsions produce a rough topographic surface. As is the case in many initially rough landforms produced by catastrophic processes, the topography of alluvial fans is progressively smoothed, producing textural differences useful in establishing relative age criteria for fans. Here, we...

Isotopic characterization of late Neogene travertine deposits at Barrancas Blancas in the eastern Atacama Desert, Chile
Here we explore the potential of spring-related, surface and subsurface carbonates as an archive of paleoenvironmental change at Barrancas Blancas, located in the broadest and driest sector of the Atacama Desert at 24.5°S. From these deposits we present a new stable isotopic record of paleoenvironmental conditions over portions of the past ~ ...

Stable C, O and clumped isotope systematics and 14C geochronology of carbonates from the Quaternary Chewaucan closed-basin lake system, Great Basin, USA: Implications for paleoenvironmental reconstructions using carbonates
Isotopic compositions of lacustrine carbonates are commonly used for dating and paleoenvironmental reconstructions. Here we use carbonate δ13C and δ18O, clumped (Δ47), and 14C compositions to better understand the carbonate isotope system in closed-basin lakes and trace the paleohydrologic and temperature evolution in the Chewaucan closed-basin...
