Professor Schoonen's research interests focus on the reactivity of earth materials under a wide range of conditions. Schoonen's research group is currently working on three major projects: heterogeneous catalysis involving mineral surfaces; carbon capture and storage; and medical geology.
Heterogeneous Catalysis on Mineral Surfaces
While catalysis, or promotion of reactions, is extensively studied in the chemical community, geochemists are only now addressing the importance of catalysis and photocatalysis in geochemical systems. Most of Schoonen's research has been directed at understanding the possible role of minerals in the conversion of relatively inert forms of biogenic elements (C, H, O, N, P, S) to small organic molecules or activated abiotic forms. Most of the recent effort in this area has been focused on studying the role of metal sulfides in the conversion of dintrogen to ammonia in the context of the Origin of Life. Schoonen's group is part of the Astrobiology Biogeocatalysis Research Center funded by NASA.
Carbon Capture and Storage
Carbon capture and storage is one of the technologies being implemented around the world to eliminate carbon dioxide from emissions associated with the burning of fossil fuel. One option is to compress the gaseous waste stream into a supercritical liquid and inject it into deep saline aquifers. Schoonen's group is conducted research on the reactivity of sulfur gases (mostly hydrogen sulfide and sulfur dioxide) which are expected to be co-injected along with carbon dioxide. The reactivity of the sulfur gases in subsurface environments dominated by supercritical carbon dioxide by itself or mixed with saline fluids is not understood. Schoonen's group conducts experimental studies to simulate the subsurface conditions and monitors the changes in the mineralogy of the exposed sediments. Some of this work is done collaboratively with colleagues Teng-fong Wong, Department of Geosciences, Stony Brook, and Daniel Strongin, Department of Chemistry, Temple University. Schoonen's research on carbon capture and storage is funded by the US Department of Energy.
Schoonen's group has been active in the emerging field of medical geology for about a decade. Research in the group focuses on mineral-driven radical formation and the interaction of minerals with biomolecules and human lung cells. The group has taken the lead in adapting a number of biomedial assays for use in mineral studies. Using these new methods, studies have been conducted on the role of pyrite in the development of black lung disease among coal miners and currently a study is being conducted to understand the effect of mineral dust on the health of soldiers stationed in Iraq and Afghanistan. Schoonen's group works closely with colleagues in Pharmacological Sciences at Stony Brook as well as colleagues in the US Geological Survey. This research effort is primarily funded through an NSF- IGERT training grant. Schoonen is on the editorial board for the journal Environmental Geochemistry and Health.
