I am a historian of science, medicine, globalization, and the cultural and intellectual history of the early modern world, with a special focus on drug history.
From August 2015 to January 2017 I was a Mellon Postdoctoral Fellow at the Society of Fellows in the Humanities at Columbia University, where I was also a lecturer in the history department.
I am now an Associate Professor of History at UC Santa Cruz. At UCSC, I teach classes on early modern Europe and the early modern world (with a focus on the Portuguese and British Empires); the global history of science, technology, and medicine; and the history of drugs, broadly construed.
I am currently accepting graduate students in these and related fields.

I earned my PhD in history from the University of Texas at Austin in 2015, where my advisor was Jorge Cañizares-Esguerra. My research in graduate school was supported by a Fulbright Fellowship to Portugal (2011-2012), a Mellon/ACLS dissertation fellowship, and grants from the Huntington Library, the John Carter Brown Library, and the McNeil Center at the University of Pennsylvania. My dissertation “Tropical Transplantations: Drugs, Nature, and Globalization in the Portuguese and British Empires, 1640-1755” won the best dissertation award from UT Austin and became the basis for my first book, The Age of Intoxication.
I have spoken about the history of drugs on PRX’s The World with Marco Werman and Radio New Zealand and have written numerous public-facing articles, including two — on George Psalmanazar and animal history — that were selected as recommended reading by The New Yorker.
I was a co-founder of The Appendix, a public-facing journal of experimental and narrative history (2012-15) and I am strongly committed to the public communication of history and community-engaged scholarship in general. Please get in touch if you think I could be of assistance as an interview subject, speaker, historical consultant, or (especially!) if you are a student interested in any of the topics I study — I am always happy to offer advice.
