Professor Casey is interested in the reactions between water, rock and minerals. Many weathering phenomena involve reactions with water on mineral surfaces, something which can be mimicked in the laboratory by studying the aqueous chemistry of metal aquo clusters by heteronuclear NMR and MS. Other interests include crystal growth, general cluster chemistry, bio-inorganic chemistry, and chemistry from an environmental aspect.
