Research Interests

In my current research, I am combining my experience in dynamic covalent chemistry (DCC) in solution pioneered by Professor Jeremy Sanders with the emergence of organic reactions performed in the solid state by ball mill grinding.  Solid state reactions can lead to the formation of polymorphs of the product.  I envisage that ball mill grinding will become a powerful tool in the synthetic chemist toolbox once the mechanism and the driving force of the reaction is well understood with the added attraction of green and clean chemistry.  This project is a close collaboration with Dr. Giulio Lampronti from the Department of Earth Sciences at the University of Cambridge; Giulio is applying his expertise in solid state chemistry and performs the Rietveld refinement of PXRD data to obtain the solid state composition of the products obtained by ball mill grinding. We are motivated to uncover the driving force of these solid state reactions by ball mill grinding.  Using disulfide exchange reaction we have demonstrated that solid state reaction by ball mill grinding is driven by thermodynamics, just as in solution.  We believe that ball mill grinding results in the formation of nanocrystals, these nanocrystals having a large surface per volume ratio which modulate the thermodynamic outcome of the reaction depending on the experimental conditions.  We are now working on demonstrating that thermodynamic driven force with ball mill grinding may be universal and can be applied to other reactions such as organic and inorganic synthesis and even polymorph and cocrystal formation of active pharmaceutical ingredients (API) obtained by ball mill grinding.
I am an expert in small molecules HPLC method development. I am pursuing my personal interest of rationalising the separation of analytes in HPLC by supramolecular chemistry.
