Dr. Lee-Geiller's research examines how technological transformation, spanning the digital and AI eras, reshapes democratic practice and how technology can be designed to strengthen it.

Her work on democratic e-governance finds that citizen experience—including information format, digital literacy, and interface design—shapes perceptions of usefulness, information overload, and institutional trust. For this line of digital participation research, she received the Walter Bagehot Prize, awarded for the best dissertation in government and public administration, from the Political Studies Association in 2024, and the Excellence in Science and Technology Research Award from ASPA's Section on Science and Technology in Government in 2025.

More recently, her work has addressed the democratic implications of AI, including its integration into elections and policymaking and the effects of AI policy narratives on public understanding and governance. Her book proposing a governance framework for the AI era is under review at Cambridge University Press.

Dr. Lee-Geiller also has extensive teaching and mentoring experience at both the undergraduate and graduate levels, in communication and media studies, political science, and AI policy.

Before her doctoral studies, she worked across government, think tanks, nonprofits, and multinational corporations.
