Portrait of Erin Lin

Erin Lin is an associate professor of political science at the Ohio State University, where she studies violence, economic development, gender, and the costs of war for soldiers and civilians alike, long after the fighting ends. Her focus is Cambodia, where American aircraft dropped roughly half a million tons of bombs in a secret campaign aimed at the Ho Chi Minh Trail — and where, fifty years later, the unexploded ordnance still determines which fields get farmed and which are left to go to seed. Her current work focuses on the Marshall Islands and legacy of nuclear displacement.

Lin's method pairs fieldwork with hard evidence. She has sat with farmers in villages built around old bomb craters and shown that what they told her scales up, matching their accounts against satellite imagery, original econometric analysis, and archival records. Lin is the author of When the Bombs Stopped, a profile of three Cambodian farmers, one village, and one minefield, showing how bombs tend to fail on the most fertile land, rendering it too dangerous to farm. The book has won more than half a dozen awards, spanning political methodology, comparative politics, and international relations.

A graduate of Yale University (BA) and Princeton University (PhD), Lin teaches courses on the politics of the developing world and qualitative writing at Ohio State. She serves on the Board of Trustees of the Mines Advisory Group, a demining and disarmament organization, and in 2022 received a Young Investigator award from the Air Force Office of Scientific Research. Before becoming a professor, Lin worked the field crew at an organic vegetable farm in Pennington, New Jersey. A North Texas native, she resides in Columbus, Ohio with her family.

When the Bombs Stopped: The Legacy of War in Rural Cambodia

Princeton University Press — Princeton Studies in International History and Politics

Over the course of the Vietnam War, the United States dropped 500,000 tons of bombs over Cambodia — more than the combined weight of every man, woman, and child in the country. What began as a secret CIA infiltration of Laos eventually expanded into Cambodia and escalated into a nine-year war over the Ho Chi Minh trail fought primarily with bombs. Fifty years after the last sortie, residents of rural Cambodia are still coping with the unexploded ordnance that covers their land. In When the Bombs Stopped, Erin Lin investigates the consequences of the US bombing campaign across postconflict Cambodia.

Drawing on interviews, original econometric analysis, and extensive fieldwork, Lin upends the usual scholarly perspective on the war and its aftermath, presenting the viewpoint of those who suffered the bombing rather than those who dropped the bombs. She shows that Cambodian farmers stay at a subsistence level because much of their land is too dangerous to cultivate — and yet, paradoxically, the same bombs that endanger and impoverish farming communities also protect them, deterring predatory elites from grabbing and commodifying their land. Lin argues that the half-century legacy of American bombs has sedimented the war into the layers of contemporary Cambodian society. Policies aimed at developing or modernizing Cambodia, whether economic liberalization or authoritarian consolidation, must be realized in an environment haunted by the violence of the past. As the stories Lin captures show, the bombing served as a critical juncture in these farming villages, marking the place in time where development stopped.

Articles

Gender After Genocide: How Violence Shapes Long-Term Political Representation

Nikhar Gaikwad, Erin Lin, and Noah Zucker · World Politics, 75(3), 2023

The Khmer Rouge killed an estimated 50 to 70 percent of Cambodia's working-age men. This lead article traces what that loss did to the country's politics: widows in the hardest-hit areas gained economic independence, and that independence opened a path into local elected office that has held for decades.

How War Changes Land: Soil Fertility, Unexploded Bombs, and the Underdevelopment of Cambodia

Erin Lin · American Journal of Political Science, 66(1), 2022

In parts of rural Cambodia, the most fertile land is also the least farmed — because it is also the most likely to hide an unexploded bomb. This article shows how the threat of ordnance, more than the ordnance itself, keeps farmers from investing in land whose payoff is too far off and too uncertain.

Crater Detection from Commercial Satellite Imagery to Estimate Unexploded Ordnance in Cambodian Agricultural Land

Erin Lin, Rongjun Qin, Jared Edgerton, and Deren Kong · PLoS ONE, 15(3), 2020

A machine-learning framework for finding bomb craters in satellite imagery, built to estimate how much unexploded ordnance remains buried in Cambodian farmland. The method more than doubled true-positive detection rates over standard approaches and suggests that 44 to 50 percent of bombs dropped in the studied areas never went off.

The Farmer's Battlefield: Traditional Ecological Knowledge and Unexploded Bombs in Cambodia

Erin Lin, Christine Sprunger, and Jyhjong Hwang · Agriculture and Human Values, 38(3), 2021

Farmers who work bomb-contaminated land have folded ordnance identification and avoidance into what counts as basic agricultural know-how. This article argues that traditional ecological knowledge isn't a fixed inheritance — it adapts, in real time, to new and often lethal conditions on the ground.


Press

Lin's research on unexploded ordnance and its long reach into Cambodian farming, land, and family life has been covered by The Economist, NPR, Gizmodo, Fox News, and The Cambodia Daily, among other outlets.
