About

Zachariah Lee Parcels

I’m a Ph.D. candidate in political science at Purdue University. My research asks how order emerges in contested spaces, focusing on the political economy of conflict, external support, institutional development, and the governance of common-pool resources during and after civil war.

My dissertation, Ruling Water: Rebels and Water Governance in Rural Colombia, examines how armed groups shape communal water management and the institutions that endure after they leave. I am also a predoctoral fellow at the SNF Agora Institute at Johns Hopkins University and a visiting researcher at the Universidad de los Andes in Bogotá.

I use a variety of methodological tools, including interviews, archival research, mechanistic process tracing, surveys, maximum-likelihood estimation, OLS, and computational text analysis with Wordfish. I have advanced methods training from Syracuse University’s Institute for Qualitative and Multi-Method Research and participate in the Qualitative Bayesian Reasoning Network.

Beyond my doctoral work, I am a graduate affiliate of the Governance and Responsible AI Lab and an affiliate of the Irregular Warfare Initiative, a joint program of the Modern War Institute at West Point and the Empirical Studies of Conflict Project at Princeton University.

01 / Research & projects

Coercion, Institutions, and everyday governance.

My work examines how armed groups govern, how communities and social institutions shape wartime order, and how outside sponsors alter the incentives and behavior of conflict actors.

Ruling Water

Rebels and Water Governance in Rural Colombia

My dissertation asks how armed groups shape community water systems and what remains after they leave. I examine when rebels dominate local water governance, when they support community decision-making, and how those choices affect water security over time.

Mountains, ornithology, and long walks that double as brainstorming sessions.

Away from research, I am usually birding, exploring a trail, or sharing the day with my wife and our goofy Boston Terrier, Ezra.
