Leslie received his LLB from the University of Edinburgh and also holds an MA (Hons.) in Greek, Latin and Ancient History and a PhD in Classics, both awarded by the University of Glasgow.
Leslie's main areas of research are in legal and intellectual history. His current research is focused on the relationship between feudal legal thought in early modern Scotland and Continental legal humanism, with a particular focus on the influence of the French humanist lawyers Bodin and Hotman.
Subsidiary research interests include the early modern and mediaeval reception of Roman law; the law of damages; property law; the concept of ownership in European thought, from antiquity to present; and the relationship between Latin antiquity and early modern Scottish law and legal thought.
Currently, Leslie is engaged in a project to produce of a Latin edition with facing English translation of Thomas Craig's Jus feudale tribus libris comprehensum, the first comprehensive legal treatise ever produced in Scotland. The first volume (of a projected three) was published in 2017 by the Stair Society, Scotland's premier publisher of legal-historical source texts. Work is ongoing on the second volume.
