My Research

My research interests involve the application of molecular biomarkers and nucleic acid based approaches to study natural microbial processes and cycles in the environment. In particular, I am focused on modern and ancient microbialites and the preservation of organic matter in carbonates. One project I am focused on is the investigation of ooid grains. Ooids are accretionary layered carbonate grains that occur in the geologic record as far back as the Archean and can still be found in restricted locations on Earth today. I am investigating how these peculiar grains form and what geochemical and geobiological information is preserved within their cortex. This project will provide important insight into how these grains form today and in the past and whether microbes are involved.

This Fellowship is in collaboration with Prof. Frank McDermott in the National Centre for Isotope Geochemistry in University College Dublin.
