After completion of his BE (1H1) and PhD degrees in Chemical Engineering at UCD, Don was appointed Assistant Professor of Chemical Engineering in 1982 at the University of Missouri-Rolla (UMR) and subsequently received tenure as Associate Professor at UMR in 1989. He returned to UCD in 1991 and was appointed to the Chair of Chemical Engineering in 2003. Professor MacElroy’s teaching interests are in Thermodynamics, Adsorption and Chromatography, Process Control and Carbon Capture. His research topics include non-equilibrium molecular phenomena in strongly inhomogeneous systems with particular emphasis on Membrane Separations Technology (notably CO2 capture), Transport in Polymer and Biopolymer Media (drug delivery and protein channels), Adsorption (difficult gas separations and recovery) and studies of the influence of far infra-red and microwave fields on the properties of polar materials (water, proteins, and solid-phase organic synthesis of low molecular pharmaceuticals). Within the scope of a recently funded SFI-SRC project, Professor MacElroy is also serving as lead-PI on research into the development of novel materials for conversion of solar energy into power, Hydrogen and low molecular weight fuels. Professor MacElroy has served on numerous review panels for funding agencies in Ireland, the UK, the EU and the US and on Scientific Committees of international conferences in Europe and the Far-East.
