Dr. Janet Burke
NSF Ocean Sciences Postdoctoral Fellow PhD: Geology and Geophysics, Yale University BS: Biological Sciences, Smith College Broadly, I am interested in the response of marine organisms to environmental changes in both modern and ancient oceans. For my PhD thesis with Dr. Pincelli Hull I studied the morphology and metabolism of planktonic foraminifera in relation to fluctuations in abiotic conditions using live cultures, sedimentary assemblages, and 3D models. As part of the Hardisty Lab, I will be working to test and disentangle the potential biological and environmental factors that influence the foraminiferal I/Ca paleoredox proxy to improve its application and interpretation.

Keyi Cheng
PhD student MS: Geology, University of New Mexico BS: Geochemistry, China University of Geosciences, Wuhan I/Ca ratio is a potential redox indicator sensitive to oxygen changes in local ocean water. However, the iodine oxidation/reduction mechanism is not fully understood, making it hard to quantitatively reconstruct the paleoredox conditions. My research focuses on understanding the mechanisms of iodine redox reactions and the ocean budget of iodine in the modern ocean. I am also very interested in reconstructing redox states of ancient oceans using I/Ca and other proxies. Checkout Keyi's recent paper published in Geology! Contact: chengkey@msu.edu |

Alexi Schnur
PhD student BS: Microbiology and Astronomy, University of Michigan Contact: schnural@msu.edu I am interested in element cycling in the modern ocean, especially that relating to iodine redox speciation, and the future implications that this type of study has on Astrobiology and planetary research. My research focuses on constraining the drivers of reactions and processes that lead to the observed spatial variability of iodine redox species found in the modern surface ocean, through seawater analyzation with spectrophotometry, ICP-MS, and MC-ICP-MS. As reactions of ozone with iodine at the sea surface are significant sinks for tropospheric ozone, an understanding of these constraints will directly inform climatological atmospheric models of the impact of sea surface iodine concentrations on tropospheric ozone levels. |
