Professor Miles is an experimental space physicist specializing in the development of next-generation spaceflight magnetic field instruments and particularly miniature instruments for nanosatellites and multi-point measurement constellations. His research interests include space weather, solar-terrestrial physics, and auroral dynamics including magetosphere-ionosphere coupling.

He is the principal investigator for the Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites (TRACERS) Mission,  the magnetic field instrument (MGF) on the Cassiopie/e-POP spacecraft (now funded by European Space Agency as Swarm-Echo) and is the instrument PI for the miniature fluxgate magetnometer (DFGM) on the Ex-Alta-1 CubeSat. He has provided  fluxgate magetnometers for  sub-orbital sounding rockets (ICI-4, ICI-5 and Maxidusty-1b) and on ACES-II in 2021.
