Dr Michael MacDonald
BE (Hons), PhD
Michael is a lecturer in Fluid Mechanics/Aerodynamics in the Department of Mechanical Engineering, University of Auckland. He graduated from the University of Auckland with a BE(Hons) in Engineering Science in 2012 and obtained his PhD in Mechanical Engineering from the University of Melbourne in 2017. He was then a postdoctoral scholar at the NASA Jet Propulsion Laboratory, California Institute of Technology in the Atmospheric Physics and Weather Group, before returning to Auckland in 2019.
Michael is interested in the numerical simulation of turbulent heat and fluid flows, including both fundamental studies and their application to geophysical and engineering flows. Michael's research aims to uncover the essential ingredients of turbulence, enabling more efficient numerical simulations to be performed.
