Aqueous Geochemistry and Mineralogy Group, led by Prof. Jeff Catalano,
studies the geochemistry and mineralogy of terrestrial and planetary
aquatic systems. Our interests span the fields of Environmental Biogeochemistry, Planetary Geochemistry, and Geobiology. The group investigates processes that control the
distribution and cycling of major and trace elements in modern and
ancient systems. These processes are controlled by chemical
interactions between water and rocks, organic matter, and organisms.
The goal of the group is to understand geochemical phenomena such as
biogeochemical element cycling, contaminant fate, and mineral
weathering and transformations on Earth, Mars, and other planetary
bodies. To accomplish these goals we
apply laboratory-based analytical, microscopy, and isotopic tools,
synchrotron-based X-ray spectroscopic and scattering methods, and
geochemical modeling techniques.
