The principal emphasis of Prof. Ashby's research is on theoretical general relativity with practical applications. For example, studies of relativistic effects within navigational satellite systems such as the Global Positioning System (a set of 24 satellites carrying atomic clocks) show that several relativistic effects must be accounted for in order for the system work properly.
