Working Papers (Selected)

Trust and Tension: Police–Community Mutual Attitudes During Stop-and-Search

Solo-authored
This empirical study examines mutual perceptions between law enforcement and marginalised communities in the UK during Stop-and-Search (SAS) encounters. It explores how trust, perceived legitimacy, and procedural justice shape cooperation, compliance, and support for policing reforms.


Smart Contracts and Financial Crime Regulation

Early-stage draft; co-authored with Prof. Séverine Saintier & Prof. Nicholas Ryder
Investigates whether the absence of a bespoke legal framework for smart contracts increases the risk of digital financial crime, compared with traditional UK contract law approaches.


An Incentive-Compatible Model of Environmental Compliance in the UK Water Sector

Solo-authored; based on my LLB dissertation
This paper examines why the UK’s Operator Self-Monitoring (OSM) system produces systematic under-reporting of water pollution. Using a political-economy and principal–agent framework, it shows how information asymmetries and low detection probabilities undermine truthful reporting. Drawing on deterrence theory and evidence from the Gujarat pollution-audit experiment (Duflo et al., 2013), the paper proposes a reform model to strengthen compliance and improve environmental outcomes.
