We are a young research group that is applying “systems” and supramolecular ways of thinking to solve problems in catalysis as it relates to organic chemistry and the chemical origins of life. Interrelated areas of focus include:
1) Aggregation in Brønsted acid catalysis
We have discovered that Brønsted acids form higher order aggregates with certain weak H-bond accepting template molecules (often solvents), which in some cases renders them dramatically more competent catalysts. We are working to deepen our understanding of this phenomenon and to exploit it to develop reactions of interest for organic synthesis, such as the direct nucleophilic substitution of alcohols , alkyl fluorides  and cyclopropanes .

2) Catalyst discovery using complex mixtures – a systems approach
We have developed a simple algorithmic approach for screening and deconvoluting complex mixtures of catalyst components with the goal of rapidly identifying new catalysts and cooperative effects. We have used this strategy to uncover new organoboron  and nickel  catalysts, and have found that catalysts selected in this way tend to be useful in multicatalysis. The continuing goal of this project is to discover new cooperative effects and multicatalytic processes.
3) Self-organized reaction networks to understand the origin of life
This ERC-funded project aims to understand how reaction networks emerge and self-organize, specifically with regard to the prebiotic origins of biological metabolism. So far, we have experimentally investigated the possibility that core biological anabolic pathways present in early life may have originated as non-enzymatic chemistry, including the acetyl CoA pathway  and the reverse Krebs cycle . Ongoing work aims to understand how networks can self-complexity over time.
4) Vibrational Strong Coupling for organic chemistry and catalysis
Vibrational strong coupling (VSC) allows a molecular vibration to be partitioned into two energetically distinct states through coupling to an appropriately sized container. A collaboration between our group and the group of Prof. Thomas Ebbesen, a world leader in VSC, aims to exploit this phenomenon for use in organic synthesis and catalysis. Thus far, we have shown that VSC can be used to change the rates of ground state organic reactions. Ongoing work aims to use VSC to modulate selectivity, to understand which functional groups and reaction mechanisms are most susceptible to VSC, as well as to explore the effect of VSC on catalysis.
