Dr. Stephanie Courouble-Share is a historian specializing in contemporary history and a researcher at the Elizabeth and Tony Comper Interdisciplinary Center for the Study of Antisemitism and Racism. She has been affiliated with the Institute for the Study of Global Antisemitism & Policy (ISGAP) in New York, USA, since 2020, and the London Centre for the Study of Contemporary Antisemitism, UK, since 2024.

A frequent lecturer at Yad Vashem’s International School for Holocaust Studies (ISHS), Dr. Courouble-Share collaborates with international organizations such as UNESCO and the World Jewish Congress (WJC), providing her expertise in combating antisemitism, Holocaust denial, and distortion (HDD). She has led significant efforts against Holocaust denial online, notably securing the removal of hundreds of Holocaust-denying books from Amazon and other e-commerce platforms.

As an expert on Holocaust denial, she has authored numerous articles in global mainstream media and on her blog, stephanieshare.com. She earned her Ph.D. in History from Denis Diderot University (Paris, France), under the supervision of Professor Pierre Vidal-Naquet. Her dissertation provided a comparative analysis of Holocaust denial across political spectrums and its presence in media, courts, politics, and the internet.

Dr. Courouble-Share has published two significant works in French: Les idées fausses ne meurent jamais, Le négationnisme, histoire d’un réseau international (Bord de l’Eau, 2021), which she plans to translate into English, and Le négationnisme: Histoire, concepts et enjeux internationaux (Eyrolles, 2023), to which Gilles Karmasyn contributed by writing several entries. She is also working on a graphic novel about Holocaust denial and distortion, expanding her educational outreach (Dunod, 2026)
