The IPUMS Terra project is managed by two groups, the Scientific Leadership Group and the Executive Committee. The Scientific Leadership Group is comprised of Project Principal Investigators and leaders of the partner organizations and determines scientific priorities for the project. The Executive Committee is comprised of professional research staff at the Minnesota Population Center and oversees implementation of the priorities and day-to-day management of the project.
Steven Ruggles, – Principal Investigator/Program Director
Ruggles is Regents Professor of History and Director of the Minnesota Population Center at the University of Minnesota. He is best known as the creator of the Integrated Public Use Microdata Series (IPUMS), the world's largest population database, spanning two centuries and more than 80 countries.

Alter is Director of the Inter-university Consortium for Political and Social Research. Alter is responsible for managing the world’s largest data archive, and he developed innovative methods for reconstructing and analyzing life histories from longitudinal data. Alter contributes to planning for IPUMS Terra's decades-long preservation and access.
Chen is Director of the Center for International Earth Science Information Network. He is a leader in multiple national and international information and data projects and groups. His research revolves around sustainable development and risk assessment, including contributions to the Intergovernmental Panel on Climate Change. Chen is helping lead efforts to integrate population data with administrative boundary data and with new time series of land cover based on remote sensing data.
Gerber is Co-Director and Lead Scientist for the Global Landscapes Initiative within the Institute on the Environment. His research develops solutions for improving global food security while minimizing agriculture’s impact on earth’s ecosystems. Gerber provides input based on potential use cases for IPUMS Terra data and tools.
Interrante is Associate Professor of Computer Science and Engineering at the University of Minnesota. Her primary research expertise is in the design, development, and evaluation of methods for the effective visualization of large multi-valued datasets. Interrante is assisting with user interface design for IPUMS Terra tools and online visualization of IPUMS Terra data.
Wendy Pradt Lougee
Pradt Lougee is University of Minnesota Librarian. She is a pioneer in major digital library development projects and was a key player in the development of JSTOR, one of the most successful models of a sustainable digital archive. She is working on fostering a scientific community interested in IPUMS Terra and on organizational sustainability.
Manson is Associate Professor of Geography at the University of Minnesota. His work combines environmental research, social science approaches, and geographic information science to understand changing urban and rural landscapes. Manson's focus is on IPUMS Terra's Geographic Information Systems and spatial data integration.
Shekhar is Distinguished McKnight University Professor of Computer Science and Engineering. He is internationally recognized for his work on spatial databases, and provides guidance for IPUMS Terra in that area.
Catherine Fitch – Executive Director
Fitch is Associate Director of the Minnesota Population Center (MPC) and founding Co-Director of the Minnesota Research Data Center (MnRDC). At MPC, Fitch has been intimately involved in the creation of several large social science databases. Her own research focuses on historical demography and marriage formation in the United States from the nineteenth century to the present. She is responsible for external communication and overseeing the organizational development committees.
Tracy Kugler – Project Manager
Kugler is responsible for day-to-day management of IPUMS Terra data processing, software development, archival development, and education and outreach. Kugler also develops and manages tools and processes for developing administrative boundary data and aggregate population data.
