    Associate Professor Gregory J Sheard

    Greg Sheard is currently an Associate Professor of Mechanical and Aerospace Engineering, and Director of The Sheard Lab at Monash University, Australia. He received his PhD from Monash University in 2004, for which he was awarded both the Faculty of Engineering Kenneth Hunt Medal and the Monash University Mollie Holman Doctoral Medal for the year's best PhD thesis. Prior to his appointment in 2006 to a permanent academic position with the Department of Mechanical and Aerospace Engineering at Monash, he held an Australian Postdoctoral Fellowship as part of an Australian Research Council funded collaboration between the Faculties of Medicine, Nursing and Health Sciences and Engineering. During this time he was awarded a Young Researcher Fellowship Award for Exemplary research in fluid mechanics, funding his travel and participation in the Third MIT Conference on Computational Fluid and Solid Mechanics, Massachusetts Institute of Technology, Cambridge MA, USA, June 2005.

    His research has featured on the Australian Ten Network's television program Scope in 2018, in Stories of Australian Science 2012, published by Science in Public, Australia's largest non-government science communication business, VLSCI Science Story #9, and Australian Life Scientist magazine.

    Dr Sheard has secured more than $2.2-million in Nationally Competitive grant funding, and has secured continuous extensive time allocations on Australia's major high-performance computing facilities worth more than $100k per year. He is the author of over 150 research publications, editorials and patents. He has supervised 8 PhD candidates to completion, and has served as examiner for 9 PhD theses and over 150 manuscripts submitted to leading journals including the Journal of Fluid Mechanics, Physics of Fluids, the International Journal of Heat and Mass Transfer and the Journal of Fluids and Structures. He chaired the highly successful 9th Australasian Natural Convection Workshop held at Monash University, December 2015, and was an Organiser for the International Conference on Computational Fluid Dynamics in the Minerals and Process Industries in 2006, 2009 and 2012. He has also chaired numerous keynote addresses, regular sessions, and advised on Technical Committees of major international conferences.

    Dr Sheard built and maintains an advanced numerical code for the simulation of two- and three-dimensional incompressible fluid flows based on the spectral-element method. Spectral-element methods combine the flexibility of finite-element approaches towards discretising complex flow domains into a grid of discrete elements with the exceptional convergence properties of spectral methods. This code has since been extended with linear stability analysis and transient growth analysis capabilities, quasi-two-dimensional and three-dimensional magnetohydrodynamics simulation, and natural convection simulation capabilities.

    Dr Stephen Dubsky

    Research Associate - Bioengineering

    Steve earned his PhD from the Department of Mechanical & Aerospace Engineering at Monash University in 2013. His thesis, entitled "Four-dimensional Computed Tomographic X-ray Velocimetry for biological applications" received the Bill Melbourne Thesis Medal for most outstanding in the Department, and the Australian Synchrotron Stephen Wilkins Medal. Steve's research focuses on the development of advanced imaging and analysis methods for 4D motion measurement in biological samples. Steve has a strong research track record, with over 30 publications and conference attendances, and more than 300 citations. He is also inventor on 19 patent/patent applications. Steve's current project is looking to use modelling and simulation to calculate clinically relevant parameters from lung imaging data, such as airway resistance, tissue compliance and gas mixing indexes.

    Oliver Cassells, PhD candidate

    Supervised in collaboration with Professor Alban Pothérat, Applied Mathematics Research Centre, Coventry University, Coventry, UK

    This project is investigating side-wall heat transfer into liquid-metal duct flows under a strong magnetic field, motivated by the operation of cooling blankets around the core of prototype magnetic confinement fusion reactors. High-resolution three-dimensional quasi-static MHD simulations will be compared with both quasi-two-dimensional simulations and theory.

    Zhi Yuen Ng, PhD candidate

    This project is uncovering the complex wake dynamics behind a triangular prism. Complex structures with sharp separation points are common in air and liquid flows across several engineering fields. This drives the need for a better understanding of the fluid mechanics around a representative bluff body. Numerical simulation and advanced stability analysis algorithms are being employed to characterise the wake stability and flow behaviour in the laminar flow regime.

    Tze Kih Tsai, PhD candidate

    This project seeks to understand the fundamental dynamics of horizontal convection under the influence of different buoyancy forcing, mechanical stirring and the effect of rotation through idealised numerical modelling. A detailed understanding of the flow structures and the instabilities will yield new insights into heat transfer characteristic and the onset of convective turbulent mixing. This project seeks to advance our understanding of the influence of various forcings on horizontal convection and its relevance to ocean circulation.

    Dr Wisam K. Hussam

    Lecturer - Australian College of Kuwait

    Dr Wisam Hussam completed a Bachelor of Science in Mechanical Engineering from Baghdad University in 1992, and a Master of Science in Mechanical Engineering/Power from al-Mustansiriya University, Iraq, in 2001. Following this, Wisam was employed as a Lecturer at the University of Technology, Baghdad, Iraq. In 2009, Wisam was awarded a scholarship from the Federal Government of Iraq to study a PhD at Monash University. Wisam's PhD investigated heat transfer in electrically conducting fluids flowing through ducts under strong magnetic fields. Wisam completed his PhD in 2012, and was then appointed as a research associate in the Sheard Lab. In 2016 he was appointed as a Lecturer at the Australian College of Kuwait.

    His research interests focuses on heat transfer enhancement, fluid-structure interaction, instability and transition in fluid flow, natural convection for Geophysical flow and Renewable energy.
