    Research Interests

    Chemistry of the polythionic acids and their corresponding salts, the polythionates. The polythionates are environmentally significant compounds. They are thought to form as intermediates in the chemical and biochemical oxidation of reduced forms of sulfur to sulfate. This oxidation process, which also results in acid production, is known to occur in aquatic systems draining mining and coal gasification operations.  Environmentally, the effects can be devastating. Addressing this problem will require a thorough understanding of the relevant chemistry, and polythionate chemistry is pivotal in that respect.
