Studies of Radio Galaxies and Starburst Galaxies using Wide-field, High
  Spatial Resolution Radio Imaging
  This thesis reports on the application of new wide-field Very Long Baseline
Interferometry (VLBI) imaging techniques using real data for the first time.
These techniques are used to target three specific science areas: (i) a
sub-parsec-scale study of compact radio sources in nearby starburst galaxies,
(ii) a study of jet interactions in active radio galaxies, and (iii) an
unbiased study of the sub-arcsecond, 90 cm sky.
