Overview

Steven is an Early Career Researcher specialising in the field of Hypersonics. His PhD thesis explored enhanced experimental methodologies to study ablation at representative in-flight temperatures within UQ’s X2 expansion tunnel, which is capable of generating the closest reproduction of Earth re-entry flow conditions of any facility in the world. The published quantitative results were the first of their kind, and provided key new insights into ablation processes. During this time he was also actively engaged in many international collaborations, including: the Ablation Radiation Coupling project funded by the European Space Agency; two separate collaborations with the United States Air Force Institute of Technology; a visit to the EM2C laboratory at École Centrale, Paris, after successfully securing travel funding through UQ’s GSITA scheme; an exchange visit to the Institute for Space Systems at the University of Stuttgart, Germany, funded by the German Academic Exchange Service (DAAD); and, he was part of an international team led by the SETI institute which conducted a remote observation and measurement campaign of the Cygnus OA6 vehicle as it re-entered the atmosphere. Steven is currently working as a postdoctoral research fellow, exploring new experimental arrangements for hypersonic ground testing with model wall temperatures representative of flight conditions.
