Laurène's research interests are in criminal justice and criminal law, in particular from a comparative point of view. Her PhD research was a comparative study of prosecutorial discretion and accountability in France and England/Wales. Her study endeavoured to understand how the French and Anglo-Welsh criminal justice systems attempt to combine the necessities of accountability for public prosecution services in modern democratic societies with the flexibility and reactivity needed in the application of the law provided by prosecutorial discretion. It combined library-based research with ethnographic observation and interviews.
