Robert Barber is a Principal Scientific Officer in the Computational Engineering Group at STFC Daresbury Laboratory. He received his Ph.D. in Computational Fluid Dynamics in 1990 and spent ten years as a lecturer in engineering fluid mechanics at the University of Salford before joining the newly established Centre for Microfluidics and Microsystems Modelling at Daresbury Laboratory in January 2000 where he now specialises in the simulation of gas and liquid flows in micron-sized devices.
Robert's main research interests include non-equilibrium (rarefied) gas flows in miniaturised systems, micro-reactors and rapid mixing devices for high-throughput life-science applications, air-segmented/capillary-driven liquid handling systems, ultrasonic particle separation devices and the design of novel microreactors for the generation of chemical concentration gradients. In addition, Robert's recent research work has involved the use of biologically-inspired principles to optimise the design of hierarchical branching microfluidic networks.
Robert has participated in research projects funded by EPSRC, MRC and European Framework programs, and has published more than 75 papers in refereed journals and proceedings, including Physics of Fluids, Physical Review E, International Journal for Numerical Methods in Fluids, Lab-on-a-Chip and Microfluidics and Nanofluidics. His work has led to invitations to organise the gas microflows session at the 3rd International Conference on Microchannels and Minichannels (Toronto, 2005) where he also gave a keynote presentation. In addition, he was invited by the Société Hydrotechnique de France to give the opening plenary lecture at Microfluidique 2006 (Toulouse, 2006). In 2009, he was invited by FRAME (the Fund for the Replacement of Animals in Medical Experiments) to give an invited presentation on the design of artificial micro-vasculatures to the FRAME 40th Anniversary Symposium on Human Alternatives to Animal Studies.
