Ahmed Timoumi is an Assistant Professor of marketing at the ISB. His research interests include Channel Management, Product Returns, and Sales Force management. He holds a PhD in marketing from Koc University, where he proposed a game theoretical approach to examine different modes of collaboration between a retailer and its suppliers in the management of some key retail functions.

This research looks at two in-store activities: Category Management and Sales Force Management and focuses on which and when a collaboration arrangement can benefit the retailer. His other research examines a particular type of product returns called wardrobing. This happens when it is bought by a consumer; used for a short time; and then returned to the store as if it were unused, for a full or partial refund.

Professor Timoumi received a degree in Mathematics and Physics from Institut Préparatoire Aux Etudes d'Ingénieurs de Tunis, and a degree in Engineering with a focus in Economics and Management from Ecole Polytechnique de Tunisie.
