Additional information

Background:

With a PhD applying radiogenic isotopes to problems involving past ocean current dynamics, my interests are strongly rooted in improving understanding of the Pb isotope system as a paleoceanographic tool.  I further study Sr, Nd, and cosmogenic Be as archives of past ocean change, rather than as chronological tools.  My past research has focused primarily on the late Miocene and early Pliocene, although I am interested in all time periods, particularly those characterized by rapid climate change and/or other interesting climate features.

 

My new post with the clumped isotope group has expanded my interests to include this exciting proxy into my toolkit. I am currently tasked with generating high precision clumped isotope data, maintenance of the measurement facilities, and working on various projects including method development of various technical aspects regarding clumped isotopes.

 

Past research has included the characterization of natural geological materials for the building industry and understanding salt weathering of natural stone.

 

Responsibilities:

As a Research Associate in the clumped isotope group, my primary role is to facilitate carbon dioxide isotopologue measurements and assist in facility maintenance. I also publish, generate grant revenue, assist with various projects and postgrad student supervision where possible, and am a contributing member to the geochronology community here at SUERC.
