   abstract: I study geologic deposits associated with springs and desert wetlands
     to understand how hydrologic systems in arid environments responded to past
     episodes of abrupt climate change. I also develop and test innovative methods
     and materials for radiocarbon dating.
   additionalType: staff profile page introductory statement
 - '@type': TextObject
   abstract: I am also part of an international team of researchers studying ancient
     human footprints in White Sands National Park. The results of our investigations
     have shown that humans were in continental North America during the Last Glacial
     Maximum, between 23,000 and 21,000 years ago, which fundamentally changes our
     understanding of the peopling of the Americas.
