This course focuses on understanding the role of microorganisms in shaping the solid surface of the Earth. This will include the major chemical and biochemical transformations by microorganisms in natural surface and subsurface environments. We will consider the contribution of microorganisms to crucial element cycles, including carbon, sulfur, and select metals, and ultimately to rock cycling. Aspects of early life on Earth, astrobiology, and environmental biotechnology will be included as appropriate. (Offered in odd numbered years.)
