Dr Travis Mitchell is a Lecturer in the School of Mechanical and Mining Engineering at The University of Queensland, within the Faculty of Engineering, Architecture and Information Technology. He earned his PhD in multiphase computational fluid dynamics from UQ in 2019, with a thesis entitled 'Development of a multiphase lattice Boltzmann model for high-density and viscosity ratio flows in unconventional gas wells'. He also holds a Bachelor of Engineering (Honours) in mechanical engineering and a Bachelor of Science in mathematics from the same institution. During his PhD, Mitchell interned at the Helmholtz Institute for Renewable Energy Production in Nuremberg, Germany, presented invited talks at Warsaw University of Technology and the Massachusetts Institute of Technology, and collaborated with researchers at the University of Pennsylvania. His early work focused on simulation methodologies for liquid-gas interactions relevant to resource extraction.

Mitchell's research expertise lies in the development, implementation, and application of numerical models for complex fluid flows, emphasizing porous media, multiphase flows, and multiphysics phenomena. Key interests include computational fluid dynamics, lattice Boltzmann methods, high-performance computing, complex bubble dynamics, and hydrogen generation from bubble reactor devices. Ongoing projects encompass gas diffusion electrodes for CO₂ electrolysis, bubble-particle interactions in hydrogen production through methane pyrolysis, particle propagation in the upper respiratory system, and multiphase transport in fractured media. As an affiliate of the Centre for Multiscale Energy Systems, he contributes to advanced energy research. In teaching, he coordinates MECH2700 Computational Engineering and Data Analysis and lectures in MECH3780 Computational Mechanics and MECH6480 Computational Fluid Dynamics. Notable awards include the ICMMES-CSRC Award for multiphase lattice Boltzmann methods, Associate Fellowship of the Higher Education Academy, and the 2023 EAIT Citation for Excellence in Student Learning. His influential publications include 'Improved locality of the phase-field lattice-Boltzmann model for immiscible fluids at high density ratios' (Physical Review E, 2017), 'A critical review of flow maps for gas-liquid flows in vertical pipes and annuli' (Chemical Engineering Journal, 2017), 'Development of a central-moment phase-field lattice Boltzmann model for thermocapillary flows: droplet capture and computational performance' (Journal of Computational Physics, 2024), and 'Hydrodynamics of molten media bubble columns for hydrogen production through methane pyrolysis' (Physics of Fluids, 2024), among others demonstrating significant impact in the field.
