Dr Maddock is an expert in mathematical modelling and system design optimisation for transatmospheric flight vehicles, including spaceplane-based launch systems. Dr Maddock received her undergraduate honours degree in 2002 in Aerospace Engineering with a concentration in Electronics and Systems from Carleton University in Canada. Her thesis was on the design of an optical inter-satellite link for a LEO-GEO data relay satellite system.
Her doctoral research was conducted at the University of Glasgow on the dynamics, navigation and control of a spacecraft formation of solar concentrators in the proximity of an asteroid. The research investigated a method for asteroid deflection/manipulation using a formation of spacecraft in proximity to the asteroid, equipped with a solar light concentrator, either mirrors/lens or lasers. By directing a high temperature spot beam into the surface of the asteroid, the regolith will sublimate and produce a low-thrust jet which will alter the orbital trajectory of the asteroid.
Prior to obtaining her PhD, Dr Maddock worked for the Canadian Spectrum Engineering Division analysing and designing future communications satellites, and sitting on a number of working parties within the Radiocommunications bureau of the International Telecommunications Union (ITU). In particular, she was a member of the Canadian Delegation, and Chair for the ITU-R Working Party 4B on performance, availability, air interfaces and earth-station equipment of satellite systems in the FSS, BSS and MSS.
