BIOGRAPHY:

I am an Earth and environmental scientist with an interest in climate change and carbon cycling. My experience and area of expertise include marine geology, paleoclimate research, isotope geochemistry, and molecular analysis of organic matter. Below is a summary of my key interests and contributions.
