About Cassandra
I am a Reader in Law at City, University of London. I am also co-founder and trustee of the Treebeard Trust.
I specialise in coercive control and the criminal law. I advise governments and activists around the world on the doctrinal implications of domestic abuse law reform, and through the Treebeard Trust support transformative initiatives to empower women affected by violence . I also run the centre for justice reform at City, University of London.
