Tatiana Andia is a third year PhD student in Sociology. Her research interests include the global political economy of development; trade, industrial policy and development; and transnational social movements.

Currently, Tatiana is studying the implementation of global pharmaceutical regulatory standards in Brazil and Colombia. In particular, she is interested in explaining why Brazil and Colombia adopted opposite policy decisions in the case of pharmaceutical intellectual property rights (IPRs) and in the case of “bioequivalence” standards for the marketing approval of generic drugs. While Brazil challenged the international intellectual property (IP) regime to favor access to and domestic production of HIV drugs, it adopted a stringent “bioequivalence” regulation that raises market-entry barriers for generic producers. In contrast, Colombia adopted strong IP rules beyond World Trade Organization (WTO) commitments but implemented a selective “bioequivalence” standard that facilitates generics’ commercialization approval. Brazil’s and Colombia’s responses to global norms are contradictory and puzzling given that the two policy issues –i.e. IPRs and commercialization approval standards- concern the same interest groups and imply very similar distributional conflicts.

Heather Randell earned a Masters of Environmental Management from Duke University in 2008 and a BS in Biology from Cornell University in 2005.  Her research centers on migration as well as displacement due to dam construction. Her dissertation uses mixed methods (household surveys and semi-structured interviews) to study the process and impacts of dam building on farming communities in the Brazilian Amazon.  Specifically, the project examines the dam-induced forced migration decision-making process, the livelihood impacts of displacement, as well as how smallholder farmers adapt their livelihood strategies to their new land and communities.
