In Brief
Work in our group targets synthetic inorganic chemistry, with the primary goal being to make, purify, and study molecules and materials that are interesting by virtue of their unusual structures and chemical reactivity.
You can find more information on who we are and what we do by clicking the links on people, research, and papers above.
