Dr Paulsen researches and teaches in the fields of international trade and investment law, international development, international political economy, and economic security. Her new article: Let’s Agree to Disagree: A Strategy for Trade Security is forthcoming in the Journal of International Economic Law. This article is the start of a broader research agenda focused on institutional improvements for WTO members to deliberate on the implications of the intersection between trade and security interests. Her forthcoming book with Oxford University Press charts the concept-building of international investment law in the early twentieth century and shows how this history reveals the unsettled foundations around economic development, security, and corporate power that continue to exist in tension today. 

Legal research into the geopolitics of trade and economic governance, drawing from the disciplines of history and political economy; trade security; tech development; the past, present, and future of the global economy and international economic governance.
