Dr

Luke Doherty PhD, BEng/BSc, AIAA Member

Departmental Lecturer in High Speed Flows

Biography

Dr Luke Doherty is a Departmental Lecturer in High Speed Flows, continuing to lend his extensive experience in experimental hypersonic aerodynamics to the department. He graduated in 2008 from The University of Queensland, Australia with Bachelor of Engineering (Hons I) and Bachelor of Science degrees. He then completed his doctorate at the same university within the Centre for Hypersonics, measuring aerodynamic forces on an airframe integrated scramjet engine in the T4 Shock Tunnel Facility.

Joining the Oxford Thermofluids Institute in 2014 as a post-doctoral researcher, and then as a Senior Researcher in 2018, he has spent the last 8 years developing, commissioning and managing the Oxford High Speed Facilities – the T6 Stalker Tunnel, the High Density Tunnel and, more recently, the Low Density Tunnel; unique facilities which have placed Oxford at the forefront of high-speed experimental research.
