Currently on research leave. A&F by appointment via MS Teams.

I joined the Department of Politics and International Studies at Warwick in September 2017 as an Assistant Professor and was promoted to Associate Professor in 2019. From September 2021, I will be the Principal Investigator on the AHRC-funded project "Latin America and the peripheral origins of nineteenth-century international order" (funded at £249,996 over four years).

Since joining PAIS, I have been nominated University Awards for "Brilliant Newcomer," "Student Experience" (highly commended), and "Research Contribution" (short-listed), and for the Warwick SU Transforming Education Awards. I am a member of Warwick's Global History and Culture Centre; I am also an Affiliated Professor at the Centro de Investigación y Docencia Económicas (CIDE) in Mexico City. In 2018, I was Fulbright Visiting Professor at the Pontificia Universidad Católica in Santiago, Chile, and have held research fellowships at Fundação Getúlio Vargas in Rio de Janeiro and Universidad de los Andes in Bogotá. I previously taught at the University of Reading, CIDE, and American University’s School of International Service, where I completed my doctorate in 2013.


My research primarily focuses on the international relations of the Americas and the dynamics of asymmetry in IR, as well as topics related to Latin American politics, North America, and small states. While my research is situated in International Relations, it draws heavily on historical sources and methods. My first book, Latin America Confronts the United States: Asymmetry and Influence, was published by Cambridge University Press in late 2015, and in paperback in 2017. It was named one of the best books of 2016 by Foreign Affairs. My second book, A Small State's Guide to Influence in World Politics is forthcoming with Oxford University Press in March 2022 as part of the Bridging the Gap Series.

My articles have appeared in major politics and IR journals including World Politics, International Security, International Affairs, International Studies Review, and Perspectives on Politics, and regional studies journals such as Bulletin of Latin American Research, Latin American Research Review, and Foro Internacional. I chair the Robert A. Pastor North American Research Initiative, and am co-editing a new volume as a result of that project.

I have done fieldwork in Argentina, Brazil, Chile, Colombia, Mexico, Panama, and the United States, supported by grants from the Fulbright Program, Tinker Foundation, British Council, the British Academy and Leverhulme Trust, and the Truman Library Institute.

More information about my research can be found on my publications page.

Doctoral supervision

I am interested in supervising a small number of exceptional doctoral applicants. Due to my current research focus, I am only looking to supervise doctoral work on the international relations of Latin America. I am particularly open to conversations with students from Latin America who are interested in studying for a PhD at Warwick.


From September 2021 to September 2023, I will be on research leave and will not be teaching.

During my time at Warwick, I have taught third-year modules “Latin America: Democratisation and Development” and “International Relations of the Americas” (PO396 and PO397). I also have directed the MA modules, “Examining Rising World Powers” (PO9B7) and "Comparing Rising Powers" (PO9A9). I am a Fellow of The Higher Education Academy. Before joining Warwick, I taught classes at the undergraduate and graduate levels on U.S.-Latin American relations, U.S. foreign policy, Latin American politics, international organizations and global governance, International Relations theory (English and Spanish), and small states.
