Martin Schoonen

Department Chair

Schoonen's research areas include environmental molecular chemistry, geocatalysis, medical geology, astrobiology, and hydrogeochemistry. An expert in synthesis, surface chemistry, and geochemistry of metal sulfides, in particular iron sulfides, his applied research efforts have included geologic sequestration of hydrogen sulfide and carbon dioxide (CO2), development of mineral-based photocatalysts, and development of acid mine drainage abatement technology. His current research projects focus on the role of iron minerals in subsurface CO2 sequestration, the use of metal sulfides as catalysts to degrade organic pollutants, and surface chemistry and reactivity of minerals under highly-saline conditions found at some DOE legacy waste sites.

While serving as Associate Vice President for Research at Stony Brook University, which since 1998 has co-managed Brookhaven Lab with Battelle Memorial Institute, Schoonen's primary responsibility was to evaluate large multidisciplinary research opportunities, form and lead teams, align institutional resources, and coordinate writing and submission of competitive proposals. He played a key role in the development of the proposal leading to the establishment of the Center for Environmental Molecular Science at Stony Brook and Brookhaven Lab. He also led a successful effort to attract a $12 million award to rebuild Iraqi universities.
