Research Interests

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

  • Late Glacial - Holocene evolution of the Indo-Australian monsoon
  • Millennial-scale climate variability of western Iberia over the last two glacial cycles
  • Shifts in Great Basin hydrologic regime across glacial/interglacial time scales
  • Extreme rainfall and drought events in tropical Western Australia during the late Holocene
  • Holocene and Late Glacial vegetation and climate dynamics in the northern Midwest and the Ozarks
