Before joining Sheffield I held positions at Keele University (2007-2018) and the College of Management, School of Law, Israel (2001-2007) and have taught in the past in Tel Aviv, Bar-Ilan and Montreal universities and visited at Cornell University, Girona University, Queensland University of Technology, and Vrije University, Amsterdam. Before joining academia, I have practised law in Herzog Fox & Neeman.

I am the author of three monographs Torts, Egalitarianism and Distributive Justice (Ashgate 2007, 2016 Spanish translation by Marcial Pons’ Philosophy & Law series), Sex Trafficking: A Private Law Response (Routledge 2013) and Egalitarian Digital Privacy: Image Based Abuse and Beyond,  and I published in English, Israeli, American, Canadian, Australian and Italian legal journals. My first monograph was shortlisted for both the 2008 Society of Legal Scholars Peter Birks Book Prize for Outstanding Legal Scholarship, and the 2008 Hart/Socio-Legal Studies Association Book Prize for Early Career Scholars. I am a grant holder (as Co-I) of Leverhulme Research Project Grant ‘FemTech surveillance: Gendered digital harms and regulatory approaches’ September 2022 – September 2024; and was previously a Leverhulme Fellow 2016-2018 for the project “Privacy law, gender justice and end users' liability: 'revenge porn' and beyond” and the Principal Investigator of an ESRC Seminar Series grant 2015-2017 “Liability versus Innovation: Unpacking Key Connections”.

My scholarship has been cited by the Israeli Supreme Court and other appellate courts, influencing the development of Israeli law in the areas of damages awards for personal injury and defamation, compensation for injuries to autonomy in medical and consumer contexts and standard of care determinations.

My anti-trafficking scholarship was cited by The Joint Committee on the Draft Modern Slavery Bill Report, was previously presented in the Israeli and UK Parliaments and was the basis for advising governmental bodies and NGOs on these matters and of several submissions to parliamentary committees including Home Affairs. My more recent work on intimate-image abused was cited by the Law Commission’s consultation paper on intimate image abuse and its final report on Modernising Communication Offences.

I am a member of the REF 2021 law sub-panel (Specialist Adviser) and of the AHRC, ESRC and ISF (Israel Science Foundation) Peer Review Colleges and an Expert Panel member of the FWO (Research Foundation Flanders). Between 2013 and 2018 I served as Keele Law school’s research director.

Teaching interests

I believe there are three main, and interrelated, characteristics to outstanding teaching which I’m trying to implement. First, research-based teaching which ensures that the teaching is updated, profound and, indeed innovative. Second, my teaching never shies away from contextualizing the legal question in both its theoretical underpinnings and its policy implications. Indeed, the opposite is true. I firmly believe that this is the high road to understanding – and teaching – law. As Duncan Kennedy commented: ‘Law students blush if asked to discuss these matters [distributive consequences of legal rules] in the publicity of the classroom’. We should blush no more, nor avoid these discussions in the classroom. Finally, I strive to excel in guiding and evaluating students' learning and research including by providing a very through feedback and by using the Socratic method to push students to the best of their ability. My goal is to take a good and motivated student and turn them into an excellent, thoughtful student.
