research overview

  • I study recent Earth history to better understand the coupled ocean/atmosphere/ice climate system. Reconstructing past environmental changes allows a better understanding of the rates and magnitude of natural climate variability, and feedbacks in the global climate system. To reconstruct the global climate system, local records must be placed in a secure independent time frame. The need for improved methods of dating these deposits fueled my interest in geochronology. My current research projects include 1) the timing, mechanism and impacts of ice growth and decay in Arctic Canada, 2) developing new or improved applications of protein diagenesis to date geological and archaeological events, 3) the role of humans in late Quaternary environmental change in Australia and Madagascar, 4) high resolution records of North Atlantic climate variability derived from lake sediment, and 5) Placing 20th century Arctic warming in a longer term perspective.
