I am a Reader in International Relations in the Department of Politics and International Studies. I joined the University of Warwick in September 2017 as an Assistant Professor in New Rising World Powers. I am currently Principal Investigator on an AHRC Standard Grant (Early Career) that investigates Latin America's engagements with and contributions to the formation of international order in the late nineteenth century.

I am the co-coordinator of the Latin America at Warwick NetworkLink opens in a new window (LAWN), a member of PAIS's Centre for the Study of Globalisation and Regionalisation (CSGR), and an affiliate of the Warwick Global History and Culture Centre. I am also an Affiliated Professor at the Centro de Investigación y Docencia Económicas (CIDE) in Mexico City. In 2023, was Visiting Scholar at Fundação Getúlio Vargas in Rio de Janeiro; in 2018, I was Fulbright Visiting Professor at the Pontificia Universidad Católica in Santiago, Chile. I have been visiting researcher at Universidad de los Andes in Bogotá and El Colegio de México. Prior to joining PAIS, I taught at the University of Reading, CIDE, and American University’s School of International Service, where I completed my doctorate in 2013.


Theoretically, my research focuses on the dynamics of asymmetrical relationships in International Relations, especially focused on the agency of relatively weaker states. Empirically, much of my work involves Latin America and inter-American relations, as well as topics related to international organizations, North America, and small states. I am interested in Historical International Relations and historical institutionalism in IR. Along those lines, I am engaged in the AHRC-funded project "Latin America and the peripheral origins of nineteenth-century international order" (funded at £249,996 over four years), with Carsten-Andreas Schulz of the University of Cambridge. 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.


My most recent book, A Small State's Guide to Influence in World Politics,Link opens in a new window was published in 2022 by Oxford University Press, as part of the Bridging the Gap Series. My first book, Latin America Confronts the United StatesLink opens in a new window: Asymmetry and Influence, was first published by Cambridge University Press in 2015 (paperback 2017). It was named one of the best books of 2016 by Foreign Affairs. My articles have appeared in major Politics and IR journals including International Organization, 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,Link opens in a new window and am co-editing a new volume, North American Regionalism: Stagnation, Decline, or Renewal?Link opens in a new window, with Eric Hershberg, as a result of that collaboration. It is forthcoming with University of New Mexico Press in December 2023. I also co-edited a policy-focused volume with Alan Bersin, North America 2.0: Forging a Continental FutureLink opens in a new window, which was released by the North American Institutes at the Woodrow Wilson Center in November 2022.

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 and the Caribbean. I am particularly open to conversations with students from Latin America and the Caribbean who are interested in studying for a PhD at Warwick.


In 2023-24, I will be teaching third-year modules “Latin America: Democratisation and Development” and “International Relations of the Americas” (PO396 and PO397).

During my time at Warwick, in addition to those two modules, I 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.

Since joining PAIS, I have been nominated for several University Awards, including "Brilliant Newcomer," "Student Experience" (highly commended), and "Research Contribution" (short-listed), and for the Warwick SU Transforming Education Awards.
