My research primarily focuses on mapping the inner structure of extragalactic radio jets in order to resolve the jet outflows. Of particular interest to my work is the measurement of the synchrotron spectra - to constrain the nature of jet-particle acceleration and energy losses, and polarisation of the radio signals - to determine the orientation and degree of ordering of magnetic field in the jet (the synchrotron radiation polarisation) and in the foreground gas (via Faraday rotation).
