My research broadly examines the processes that control deposition of carbonate rocks in lakes (and other non-marine environments). I am particularly interested in research areas relating to:

  1. Rate, timing and mechanism of carbonate growth, particularly with respect to different facies types;
  2. Controls on spatial and temporal variation of facies, growth rates, and depositional processes:
  3. Basin-scale relationships between carbonate growth and hydroclimatic variation over time.

In order to examine these processes, I rely on a variety of investigative methods. I use trace element and stable isotope geochemistry and petrography, along with age dating techniques like radiocarbon dating, to evaluate when the carbonates are forming, how fast they grow, and what depositional environment they are most likely growing in. This information can also help me to evaluate the role that microbial life may play in the deposition of these rocks. This information then allows me to examine changes in lake basins over time. Combined with more traditional paleoclimate and paleolimnology techniques such as sediment coring, I can then attempt to understand the relationships required to produce large volumes of carbonate rocks in this type of setting.
