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.

Turbulence is prevalent in engineering and nature but despite a century of research, the prediction of turbulent flows remains a challenge. Advances at the fundamental level are therefore necessary and, towards this end, Daniel's research distils the complexity of turbulent flows into simple yet essential configurations that, aided by simulation and modelling, yield insights into the inner workings of turbulence.
