Sean Murray

PhD., University of Miami, 2016

BSc Geological Sciences (2009), University of Miami

Development and Application of Clumped Isotopes to Carbonate Geochemistry

Research interests: My interests involve the influence of diagenesis and dolomitization on the clumped isotope paleothermometer. My work is mostly focused in the Bahamas where I examine young dolomites with well constrained geologic histories. I have also dabbled in dolomites from the Madison and am also currently attempting to precipitate equilibrium calcites for use in standardizing clumped isotope paleothermometry.

Viviana Diaz

PhD Student since 2011 (Supervisor Prof. James Klaus and Donald F. McNeill)

Research interests: Evolution of Plio-Pleistocene fringing reefs in the southern Dominican Republic. The goal is to develop an integrated sequence stratigraphic model that characterizes both depositional and diagenetic trends and the large-scale porosity and permeability distributions that result with repeated cycles of freshwater and marine diagenesis from regional uplift and high-amplitude changes in sea level.

Kimberly C. Galvez

PhD Student since 2014 (Supervisor Prof. Gregor Eberli) 

Research interests: Observe and assess the development of cold-water corals in the Straits of Florida through means of determining age of the current and fossilized CWC systems using radiometric dating technology and assessing the formation of the carbonate mounds sedimentological facies deposition over time. Determining age and species variability of these corals and their environments may provide insights into geological and biological formations in that region.

Chelsea Pederson

PhD Student since 2012 (Supervisor Dr. James Klaus, Assistant professor)

Research interests: My research focuses on microbial microbial deposits in the geologic record. Currently, I am working on an integrative study focusing on the deposition and preservation of freshwater microbial carbonates in the Florida Everglades. The main objective of this research is to analyze a microbial carbonate deposit from deposition to early burial. Through integrative analyses, a pedigree will be created for freshwater microbialites by tracking characteristics and geochemical signals through various stages of burial.

Previous education: BSc in Marine Science and Biology from University of Miami, FL.
