Dr. Joy Kategekwa is a Ugandan international trade and investment law specialist currently working with the World Trade Organization's development division- where she focuses on special and differential treatment negotiations and African issues in the DDA. Before joining the WTO, she worked with Oxfam International's Geneva Office as a Trade Policy Advisor and before that, with the South Centre as a Program Officer on Trade in Services. In both roles, she was responsible for providing technical negotiation support to LDCs and developing countries in, inter alia, the GATS Mode 4 negotiations. Prior to that, she represented her country in the WTO's Doha negotiations; notably in the areas of services, intellectual property and special and differential treatment. Her research interests are in the development aspects of WTO law and in trade in services: the latter being the subject of several of her publications. Dr Kategekwa approaches this research with the advantage of a practitioner's perspective.
