Leon Y. Xiao is a PhD Fellow at the IT University of Copenhagen, with visiting appointments at Stanford Law School and York’s Computer Science Department. He researches video game law, particularly the regulation of loot boxes – a quasi-gambling monetisation mechanic in computer games. He uses empirical legal research methods and is passionate about open science. Leon’s research has been referenced (twice!) in the House of Lords and is often featured in the media. He has been invited to advise policymakers and regulators, including the UK Government. Game companies have also taken direct compliance and remedial actions following his research.
