Bio

Christian Twigg-Flesner joined Warwick Law School in September 2017. He is Professor of Contract and Consumer Law.

He read law at the University of Sheffield (LLB in 1997 and PhD in 2002). He started his full-time academic career at Nottingham Trent University (1999-2002) before returning to Sheffield as Lecturer (2002-4). He joined the University of Hull in 2004 as Lecturer and was Professor of Commercial Law there from 2010 to 2017.

Professor Christian Twigg-Flesner's research interests are broadly in the fields of Contract Law, Consumer Law, and Commercial Law. This includes domestic aspects (English Contract Law, UK Consumer Law, and transactional aspects of Commercial Law), European aspects (especially EU and comparative Consumer Law), and international/transnational dimensions (both Transnational Commercial Law and International Consumer Law).

The focus of his current research is the impact of digitalisation on these fields. This includes specific topics (e.g., automation of transactions through algorithms and Artificial Intelligence; 3D-printing; online platforms; or data transactions) and overarching themes (analytical methodology for law and technological change; legal disruption; shifts in the role of contracts from transactions to networks and governance systems).

His most recent books are Foundations of International Commercial Law (Routledge, 2021) and the co-edited (with Hans Micklitz) The Transformation of Consumer Law and Policy in Europe (Hart, 2023). He has also published widely on European Consumer and Contract law, including Rethinking EU Consumer LawLink opens in a new window (with Geraint Howells and Thomas Wilhelmsson) and The Europeanisation of Contract Law (2nd ed, 2013), and the edited Research Handbook on EU Consumer and Contract Law (Elgar, 2016).

Guiding Principles and Model Rules on Algorithmic Consumer Contracts

Professor Christian Twigg-Flesner, together with Professors Teresa Rodríguez de las Heras Ballell, Christoph Busch, and Marie Jull Sørensen, is a co-reporter for a European Law Institute Project on "Guiding Principles and Model Rules on Algorithmic Consumer Contracts". The team will focus on the use of Algorithmic Decision-Making (ADM), especially Artificial Intelligence (AI) system utilising machine learning, in all the stages of the consumer contract life-cycle. Christian is serving as person-with-file (lead co-reporter) for this project.

More information is available fromthe project webpages.

Smart Technology and Consumer Protection

Legal experts at the Universities of Stirling, Osnabrück, Warwick, and Bonn have launched a new study to ensure that consumer laws are as ‘smart’ as the emerging technologies that they regulate. This three-year project, running from February 2022 to February 2025, is funded by the AHRC-DFG UK-German Funding Initiative in the Humanities.

More information is available fromthe project webpages.
