Democracy, Identity & National Security

Research on belonging, public trust, and democratic life after 9/11

Rachel’s early research examined how national security policy, immigration, identity, and belonging shape democratic trust. At Stanford, she led the Muslim American National Opinion Survey, one of the first nationally representative surveys of Muslim Americans in the United States.

Combining survey data, interviews, and policy analysis, her work explored how communities experience government institutions, how trust is built or eroded, and how democratic societies navigate security concerns while protecting belonging and equal citizenship. This research culminated in peer-reviewed publications and the book Muslims in a Post-9/11 America, published by the University of Michigan Press.

Book cover titled "Muslims in a Post-9/11 America" by Rachel M. Gillum, featuring a stylized American flag with red, white, and blue colors and white stars at the top.

Muslims in a Post-9/11 America examines how Muslim Americans experienced national security policy, law enforcement, belonging, and political life in the years after 9/11.

Drawing on one of the first nationally representative surveys of Muslim Americans, along with extensive interviews, the book challenges narrow portrayals of Muslim American communities as homogeneous, isolated, or politically suspect. It shows a diverse population shaped by race, ethnicity, immigration history, religious identity, and generational experience.

The book’s central argument is about democratic trust: policies designed in the name of security can weaken relationships between communities and government when they are built on suspicion rather than understanding and empirical data. Rachel argues for public policy and law enforcement approaches that protect security while strengthening trust, belonging, and equal citizenship.

“This work makes a significant contribution to the field, not only through its substantive findings on trust in law enforcement but also because it is one of the few nationally representative surveys of Muslim Americans. The insights in this book will help us assess where we are as a nation and where we need to go.”

Condoleezza Rice, Stanford University, former U.S. Secretary of State & National Security Advisor

“Gillum provides a compelling, well-researched, and sophisticated understanding of the distressing impact Islamophobia has had on the Muslim American community. Gillum engages American popular and mainstream convictions that feed into today’s existing Islamophobic climate. Drawing on original surveys of Muslim and non-Muslim Americans, Gillum finds that there are very few differences between Muslim and non-Muslim Americans on variety of attitudes related to violence, terrorism, and patriotism. This is an excellent and timely book which should be widely read.”

“This is the first study that I have seen that has parsed generational and ethnic/racial differences in attitude among Muslim Americans rather than viewing these communities as a monolith . . . This book combines both the statistical angle and interviews in an illuminating way.”

Muslims in a Post- 9/11 America is a lucid examination of the attitudes of American Muslims toward U.S. counterterrorism and other policies that have heightened levels of racialization, surveillance, and discrimination.  Drawing on empirical evidence, Gillum argues that policies fueled by religious profiling and discriminatory suspicion undermine their own efficacy. The book provides important contributions to the study of American Muslims, their experiences, and how the U.S. government has viewed them and targeted them unjustly.”

“Rachel Gillum’s excellent book could not be more timely and important at this stage in American politics. It is the definitive account of who American Muslims are and what they think, a much-needed antidote to prejudice and misconception, and a clear warning about the unintended consequences of counterterrorism policies.”

Martha Crenshaw, Stanford University, Senior Fellow at the Freeman Spogli Institute for International Studies

Muslim Expectations of U.S. Law Enforcement Behavior

Chapter in Understanding Muslim Political Life in America

Rachel contributes the chapter “Muslim Expectations of U.S. Law Enforcement Behavior” to Understanding Muslim Political Life in America: Contested Citizenship in the Twenty-First Century, edited by Brian Calfano and Nazita Lajevardi.

The book brings together leading scholars to examine Muslim American political life in the post-9/11 era. Rachel’s chapter focuses on expectations of U.S. law enforcement behavior, connecting questions of security policy, fairness, political belonging, and democratic trust.

This research continues to shape Rachel’s work on AI governance, where questions of institutional power, democratic accountability, and public trust are increasingly central to how advanced technologies are designed and deployed.
