Steve Petsch is an associate professor of geosciences at University of Massachusetts Amherst. His research addresses what happens after deposition of organic matter in sediment, including processes such as diagenesis, chemical decomposition and the existence of metabolically active microorganisms at the deepest and most extreme extent of exploration. His research tests the limits of what it means to be refractory, labile or biologically available, by exploring the degradation, dissolution and utilization of ancient organic matter in soils, aquatic systems and the deep subsurface.
