Research Interests

My research primarily involves the use of stalagmites and corals as paleoenvironmental records to investigate the following:

  • Glacial and recent evolution of tropical Australian rainfall associated with the Australian monsoon and tropical cyclones
  • Climate variability of western Iberia associated with sea surface temperatures and the North Atlantic Oscillation
  • Shifts in Great Basin hydrologic regime across glacial/interglacial time scales
  • Vegetation and climate dynamics in the midwestern United States
  • El Niño-Southern Oscillation activity in the Miocene and Pliocene "greenhouse worlds"
