His research involved the role of metal ions in biological systems inluding: iron in marine environments, especially the iron storage and DNA protective proteins ferritin and Dps; the biological production of hydrogen by phototropic hydrogenases and theoretical studies of hydrogenase action; the role of molybdenum in biology; and aspects of metals in medicine. He taught courses on the Elements of Life for freshman, Astrobiology for sophomores and Metals in Biology for advanced undergraduates and graduate students. He served on the Board of Reviewing Editors of Science and the Board of Editors of the Journal of Inorganic Biochemistry.
