A/Prof Daniel Chung

Dr Daniel Chung is an Associate Professor in the Department of Mechanical Engineering at The University of Melbourne.

Biography
Daniel graduated from The University of Melbourne with a BE (Mechatronics) / BCS in 2003, and then went on to complete his PhD (Aeronautics) at the California Institute of Technology in 2009. Then he was a postdoctoral scholar researching climate physics at the NASA Jet Propulsion Laboratory before joining the department as Lecturer in 2012.

Research Interests
Daniel is interested in interdisciplinary research centred around fluid mechanics, including large-eddy simulation and modelling, direct numerical simulation, wall-bounded turbulence (especially over roughness), turbulent convection and planetary boundary layers.

Daniel's research is fundamental in nature, aimed at developing and improving the predictive tools used in engineering and meteorology.
