I am a NOAA Climate and Global Change Postdoctoral Fellow and Visiting Postdoctoral Fellow at Princeton University working with Professor Michael Bender.  As a stable isotope geochemist with interests in Earth’s history and climate change, I apply isotope techniques to reconstruct paleotemperature and study the carbon cycle. 

Research:

My research is primarily focused on applying isotopes of carbon and oxygen to minerals - mostly carbonates and bioapatite - preserved in Earth’s sedimentary record to understand climate change and the carbon cycle over many timescales in Earth’s history.  My research ‘toolkit’ includes clumped isotope thermometry and triple oxygen isotopes.  Please see my research page for further information.

News: 
The new TC/EA in the Bender lab has been installed! Watch this space for new oxygen isotope results from biogenic phosphate.

Dennis et al. (2011) was published in Geochimica et Cosmochimica Acta.  This paper culminates a multi-lab effort to develop an inter-laboratory reference frame for the clumped isotope community.

I recently defended my PhD, “Clumped isotope paleothermometry and its application to Earth’s history”, in the Department of Earth and Planetary Sciences at Harvard University.
