Dr Jon McCullough joined Queen's University Belfast in October 2024 as a Lecturer in the School of Mechanical and Aerospace Engineering. Prior to this he was a postdoctoral Research Fellow within the Department of Chemistry in University College London.  Jon has degrees in Mechanical Engineering (BE(Hons)) and Mathematics (BSc) from The University of Queensland. He also obtained his PhD from The University of Queensland within the School of Mechanical and Mining Engineering.

Jon's research has focussed on the numerical simulation of complex fluids using the lattice Boltzmann method. This has included the study of particle suspensions within the oil and gas industry, and the simulation of macroscale blood flow within human-scale models of the arteries and veins. These practical applications have been supported by efforts in algorithm development and the deployment of codes on high-performance computers for both CPU and GPU architectures including on some of the largest supercomputers in the world.

Jon's work has been supporting wider efforts in areas including the development of digital twins for biomedicine and healthcare, implementation of validation, verification and uncertainty quantification techniques for numerical tools, and the visualisation of large-scale complex data arising from simulations.
