Constraints on dark matter models from strong gravitational lenses observed with VLBI

Strong gravitational lensing by galaxies provides us with a powerful laboratory for testing dark matter models. Various particle models for dark matter predict different small-scale mass features in lens galaxies, which can be probed using sufficiently sensitive observations of the lensed images.  Milli-arcsecond resolution very long baseline interferometric (VLBI) observations have proven to be well-suited for this task. In this talk, I will present my recent work on dark matter constraints using VLBI observations of strong lenses in the context of warm dark matter (WDM) and ultra-light dark matter (ULDM) models. I will also discuss the key role that VLBI observations will play in revealing the nature of dark matter, in light of the ~10^5 gravitational lens systems with radio-bright sources which will be discovered by the Square Kilometre Array.
