Hannah's thesis looks at how people with disabilities are used as exceptions and resolutions to aporetic puzzles in the law, in particular how this shapes the law's own self-conception. Her focusses are on constitutional definitions of judicial power how we can use innovative methodologies in law to uncover new understandings about the treatment of minority groups. She uses Derrida and Agamben as part of a framework synthesis and scoping review approach, all with a view to placing a critical lens over the rights or lack thereof of people with disabilities in law.

Hannah is also a disability activist. She is organiser of Australia's only disability pride parade in the grand global tradition started by Chicago. She served on the board of People with Disabilities Australia and as Chair of their Governance Committee, of which she remains a member. She founded and remains leader of the Sydney Epilepsy Jacaranda Club, a movement of support by and for people with epilepsy in the New South Wales area. She also participated as a expert advisor at Women with Disabilities Australia, and sits on other access committees. Prior to her PhD she served in the Extraordinary Chambers of the Courts of Cambodia. Before becoming a lawyer, Hannah was a language teacher, in which area she completed her masters and won the prestigious Vice Chancellors' Award for Outstanding Contributions to teaching and learning. She retains a lively interest in the intersection between linguistics and law.
