Nabil Boctor researches phase equilibria, kinetics of mineral reactions, element partitioning between minerals and melts, and igneous and ore petrology. Boctor did his Ph.D. research with former Geophysical laboratory staff Gunnar Kullerud in the area of sulfide phase equilibria.
Dina Bower’s research is centered on finding and establishing reliable biosignatures in ancient rocks on Earth and other planets. She attempts to understand the role of microbes in the diagenesis of Fe-Ti-oxides by undertaking experiments that simulate diagenetic conditions. Currently, she is studying ~1.9 Ga Gunflint chert samples collected from four different sites of the Gunflint Formation.
Henderson (Jim) Cleaves' research in organic geochemistry is concerned principally with abiological organic synthesis, the question of how life arose on Earth, and methods for detecting Life on other planets. Presently he is involved in a project with Robert Hazen regarding the interactions of organic compounds with mineral surfaces.
George D. Cody specializes in chemical-structural analyses of solid phase organics. His research is focused on determining the diagenetic reactions that define organic sediment maturation. Other interests include examining the molecular structure of extraterrestrial organic solids contained within carbonaceous chondritic meteorites and more recently, comets. He received a Ph.D in geosciences from Pennsylvania State University in 1992, and a BSc in geology from University of Massachusetts at Amherst in 1982.
Jennifer Eigenbrode is a biogeochemist and geologist with expertise in organic and isotope geochemistry and interests in astrobiology. She specializes in the use of gas chromatography-mass spectrometry (GCMS) in the analysis of lipids and other hydrocarbons in rocks, ice, and biological samples.
Marilyn L. Fogel's research revolves around the stable isotopic biogeochemistry of modern and fossil ecosystems. She uses stable isotopes to trace biochemical and geochemical processes. She received a Ph.D in botany from the University of Texas at Austin, Marine Science Institute in 1977 and a BSc in biology from the Pennsylvania State University in 1973. Marilyn is now a Professor at the University of California Merced for the School of Natural Sciences. At UC Merced, Marilyn will provide leadership and support to current faculty research in biogeochemical cycling and ecological studies of past and future environments in the context of changing climate. She plans to establish a stable isotope laboratory capable of supporting research in ecology/paleoecology, biogeochemistry, and environmental sciences, which will serve as an integrator for interdisciplinary studies related to climate change, biodiversity, and sustainability sciences.
Mihaela Glamoclija's research relates to general area of microbe-mineral interaction, utilization, and development of methods and concepts that may aid in the search, detection, and assessment of fossilized microbial life on Earth as a guide to the search for ancient life on Mars.

He received a Ph.D in physics from the Russian Academy of Sciences, Institute of Spectroscopy in 1983, and a combined MA and MSc in physics from the Moscow Institute for Physics and Technology in 1979.
Robert M. Hazen's research encompasses the origins of life and emergence of pre-biotic chemical complexity. Topics of particular interest include the interactions between crystalline solids and organic molecules and the co-evolution of geo- and biospheres. he obtained a Ph.D in mineralogy and crystallography from Harvard University in 1975, and a BSc and SM in earth science from Massachusetts Institute for Technology in 1970 and 1971.
Russell J. Hemley is a senior staff scientist of the Geophysical Laboratory. His research examines the properties of materials at high-pressures and its applications to geophysics, geochemistry and planetary science, as well as to theoretical condensed-matter physics and chemistry. He uses optical spectroscopy, x-ray diffraction, and diamond-cell techniques to conduct high-pressure experimental and theoretical studies in condensed-matter physics, earth and planetary science and materials science. He obtained a Ph.D and MA in physical chemistry from Harvard University in 1983 and 1980, and received a BA in chemistry and philosophy from Wesleyan University in 1977.
Garret is responsible for building and maintaining the IT systems at the Geophysical Laboratory, which includes the network, server systems, web services, telepresence systems, and automation code for scientific instrumentation. In addition, he builds IT systems for the AMASE expedition and is currently the IT lead for the NAI grant.
Danielle is the assistant to the director at the Geophysical Laboratory. Prior to joining Carnegie in 2007, Danielle worked as Consultation Executive for one of the top planning and PR firms in London, Local Dialogue LLP, where she led the consultation on large-scale public sector projects for the Mayor of London including "Crystal Palace Park Regeneration," the "Olympics 2012," and "Ocean New Deal for Communities Redevelopment."
Adrienne Kish is an astrobiologist with an interest in the microbiology and molecular biology of extremophiles exposed to the types of environmental conditions found on planetary bodies such as Mars and the icy moons of Jupiter and Saturn.
Bjørn O. Mysen's areas of research include experimental high-temperature and pressure analyses, investigations into the properties and processes of rock-formation and related materials with an emphasis on melting. He is also interested in examining the phase relations of mantle materials, fluids in melting processes, the properties and structure of melts and glasses, element partitioning between minerals, fluids and melts at high-pressures and temperatures.
