Profile

I received a 1st class B.Eng.(Hons) from the Department of Aeronautics City University and a Ph.D. from the Department of Aeronautics and Astronautics University of Southampton. As EPSRC Research Fellow at the Department of Aeronautics and Astronautics University of Southampton (1996-1997) I studied vortex boundary layer interactions by laser velocimerty. I developed time-resolved numerical models of unsteady transonic flows as EU Marie Curie Fellow at the Department of Aeronautics and Aerospace von Karman Institute for Fluid Dynamics Belgium (1998). After that he moved to the Department of Engineering University of Leicester as Lecturer (1998-2010) Senior Lecturer (2010-2016) and then Associate Professor.

Research

Dr Rona coordinated the ""Aeronautical Trainning Network in aerodynamic noise from widebody civil aircraft"" AeroTraNet 2 project (2012-2016). Funded by a €2.8M FP7-PEOPLE-2012-ITN grant from the European Commission this Marie Curie Integrated Training Network of the 7th Framework Programme (FP7) trained 11 Early Stage Researchers and 1 Experienced Researcher in modelling shock-associated noise and in the knowledge capturing and knowledge management of the research output. Dr Rona and Prof. S.V. Hainsworth (PI) set up and opened in 2014 the Advanced Structural Dynamics Evaluation Centre (ASDEC) at the MIRA Technology Park Nuneaton. Funded by £1.07M Regional Growth Fund and £0.25M European Regional Development Fund grants ASDEC is the first UK centre providing access to robot 3D Laser Doppler Velocimetry to industry SME and research institutes.
