Prof. Williams has published over 100 papers in refereed journals and been granted international 5 patents. His research interests include the surface and bulk characterisation of complex organic solids, including especially biopharmaceutics, foods, pharmaceuticals and polymers as well as their manufacture using spray drying, crystallisation, freeze drying, milling and granulation. The Surface and Particle Engineering Laboratory at Imperial College he leads has 4 Postdoctoral research fellows and 11 PhD students.
He has invented one and has led the commercialisation of two standard techniques for materials characterisation, the Dynamics Vapour Sorption (DVS) and the Inverse Gas Chromatography (IGC) methods via Surface Measurement Systems. His work has been recognised by Imperial College with the President’s Medal in 2017, the EEF’s Future Manufacturing Award in Innovation for 2018 and the Institution of Chemical Engineers’ Geldart Medal in 2018/19 for his “major contribution to particle technology”.
