My research work sits at the intersection of comparative administrative law, regulated industries, public policy, and water and sanitation governance.
I focus on how legal and regulatory frameworks operate across jurisdictions, with particular interest in regulatory compliance, risk, governance, and policy implementation in highly regulated sectors.
Through comparative research, I examine how institutions balance innovation, accountability, and public interest.
