​​​​​​​​Elizabeth Ty Wilde is a Senior Research Officer at The Wallace Foundation, where she contributes to strategy design, identifies policy challenges and opportunities, and analyzes the impact of related empirical and theoretical approaches to addressing policy problems.

Before joining Wallace, Wilde was an Assistant Professor in the Department of Health Policy and Management in the Mailman School of Public Health at Columbia University. Her research was focused on improving health outcomes by changing the institutions that directly provide health care or influence health through other mechanisms (such as community housing agencies or elementary schools). Projects she worked on involved studying the impact of a randomized welfare reform experiment on long-term health, investigating a federal initiative to reduce homelessness, and researching the impact of small class sizes on mortality, earnings, employment, and disability. Her research has been published in journals including the American Journal of Epidemiology, the Journal of Policy Analysis and Management, the Journal of Health Care for the Poor and Underserved, Health Economics, and the Journal of Clinical Oncology. Wilde has a PhD in Economics from Princeton University and a BA in Economics from Swarthmore College. Previously, she worked as a management consultant at the Monitor Group.​​​​
