Race, Policing, and Institutional Trust: A Century of U.S. Laws and Social Inequality


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

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

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

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.
