Astrobiology, Geochemistry, Mineralogy

Please welcome back to campus Lavontria Miché Aaron. Aaron will be a Visiting Investigator from Johns Hopkins University working with Steelie for the next year, researching spectroscopic remote sensing of calcium oxalates on Mars. Her research interests include: Spectroscopy, Mineralogy, Remote Sensing, and GIS.


Jordan Wostbrock of the University of New Mexico will deliver a seminar on "Seeing through carbonate diagenesis using the triple oxygen isotope system."

Astrobiology, Geochemistry, High Pressure

Dr. Vincent S. Riggi joins EPL as a Postdoctoral Fellow working with Andrew Steele. Riggi received his Ph.D. from Rensselaer Polytechnic Institute in Troy, New York. He will be working on abiotic carbon dioxide reduction in the context of prebiotic chemistry and astrobiology. Experiments will test novel CO2 reduction mechanisms and their feasibility in natural systems. His research interests include astrobiology, prebiotic chemistry, organic synthesis, and high pressure/high temperature geochemistry. 


Dr. Mojhgan A. Haghnegahdar of Department of Geology at the University of Maryland presented a seminar titled, "Can Measurements of 13CH3D & 12CH2D2 Help Us Understand the Atmospheric Methane Budget?"


Dr. Matthieu Galvez of ETH in Zurich delivered a special Wednesday seminar entitled, "How Mountains React and Breathe."


Dr. Jill Mikucki of the University of Tennessee Knoxville delivered a seminar entitled "On the exploration of Antarctic subglacial microbial ecosystems."

Geochemistry, Planetary Science

Dr. Xike "Nicole" Nie comes to GL from the University of Chicago. For the next two years, Nie will be working with Dr.
