Aaron Bloomfield grew up in Ithaca NY, and remained there to attend Cornell University, where he majored in chemistry and performed undergraduate research with Professor Stephen Lee, studying the structures of intermetallic compounds using computational methods. After graduating with honors, Aaron attended Yale University, where he developed new synthetic techniques for making secondary and tertiary phosphine oxides, and discovered a novel class of heterogeneous electrocatalysts based on a cobalt hydroxide/bis-tertiary phosphine oxide coordination polymer. After earning a PhD, Dr. Bloomfield conducted research as a postdoc with Professor Paul Anastas at the center for Green Chemistry & Green Engineering, and with Professor Robert Crabtree at the Energy Sciences Institute. Dr. Bloomfield joined the faculty at Duquesne University in 2018, and moved to Pittsburgh with his family. When he isn't working or spending time with his family, Aaron enjoys playing speed chess, swing dancing, and hiking.

The Bloomfield Group is focused on experimental synthetic chemistry. We prepare compounds that have never existed before, and find new (hopefully better) ways to make compounds that are already known and valued. Our primary goals involve the discovery of sustainable and environmentally friendly catalysts, which can be used for efficient and effective synthetic methodology and/or energy storage. We are especially interested in determining the underlying structure-activity relationships within classes of structurally similar catalysts, which will ultimately allow us (and others) to design new and better catalysts in a rational and purposeful way.

Our interests span organic, inorganic, and organometallic compounds, though most projects in the Bloomfield Group involve phosphorus compounds in one way or another. Many projects also involve late 1st-row transition metals like cobalt and nickel, but we generally avoid working with precious metals. All compounds of interest (so far) have well-defined molecular structures, or are coordination polymers with well-defined molecular monomeric subunits.

Finally, while we do aim to advance the state of the field through discoveries and results obtained through the research in our lab, my primary objective is to advance the sate of the field by producing good scientists, who will continue to push the field forward long after graduating from the group, be it in academia, industry, medicine, government, or other careers.
