ABOUT ME

Ph.D. 2008 Stanford University
B.S. 2000 Missouri University of Science & Technology

My research uses geochemical tracers in the modern environment and on ancient samples to test our understanding of biogeochemical cycling in the ocean with the ultimate goal of better constraining these processes and understanding records of the past. I employ non-traditional stable isotopes (Ca, Sr, Mg) in combination with more traditional paleoclimate proxies.

I most enjoy working with students in the field and in the lab- discovering new things about the world around us using geochemistry.

Samantha Carter

PhD candidate

MS 2015 UT Arlington

BS 2012 Texas A&M Univ.

I’m primarily interested in using geochemical techniques to solve problems within the field of paleoclimatology so that we can gain insight into Earth’s climate system. My dissertation is primarily focused on reconstructing chemical weathering intensity using the isotopic composition of strontium in clays to investigate monsoon variability over long time scales. I am also interested in carbon cycle dynamics over periods of rapid climate change.

Brittan Wogsland

MS student since May 2018

BS 2016 Vanderbilt Univ.

I am primarily interested in the search for life in our solar system and the surface processes of the rocky planets, especially Mars. My current research uses the geochemistry and calcium stable isotopes of hypersaline stromatolites from the Bahamas to further illuminate their formation and early lithification processes.

Ji-Eun (JJ) Kim

PhD student since 2018

MS 2018, BS 2016 Pusan National Univ., Rep. of Korea

My focus lies on reconstructing the past environment of Earth through marine sediments using geochemical proxies. I am currently studying the change of export productivity in the Cretaceous . In the past, I also did research on Monsoon variability at the Arabian Sea using IODP cores. I am interested in learning more about biogeochemical proxies and how to apply them to various settings.

Gregory Aaron

MS 2012 Kent State University

Greg is currently employed at the Pennsylvania Department of Environmental Protection (2013-present).

My thesis research focuses on global export production through the analysis of marine barite in marine sediment deposited during the PETM, ETM2 and ETM3 hyperthermal events in the early Eocene. The goals of the project is to compare the impacts of the hyperthermals on export production, potential mechanism differences between the hyperthermal events and if there is a connection between export production and benthic foraminiferal accumulation. I am interested in geochemical processes that are related to marine organisms and paleoclimate reconstruction.

My research aims to explore the growth of modern hypersaline microbialite. I integrate field, petrographic and geochemical work in the study. Specifically, I apply Mg isotope to untangle the environmental condition and mineralogical control during microbialite formation and early diagenesis.
