About MDI

The Massive Data Institute (MDI) at Georgetown’s McCourt School of Public Policy focuses on the secure and responsible use of data to answer public policy questions. MDI works with researchers in government, academia, and industry to solve societal-scale problems using novel and traditional large-scale data sources. MDI’s strategic partnerships promote community and innovation across the health, social, computer, and data sciences.

MDI draws on expertise from across Georgetown’s campus and beyond, including the social, natural, and computer science departments, and through strategic partnerships with organizations like the Beeck Center for Social Impact and Innovation, Lawrence Livermore Laboratories, the Institute for Social Research at University of Michigan, and the Pew Charitable Trust. The U.S. Census Bureau has designated MDI a Federal Statistical Research Data Center, one of only 23 in the nation.

The ​MDI regularly awards seed grants, houses post-doctoral fellows, and hosts panels and faculty seminars on public policy and massive data.

Directions to MDI

From the main gates, you enter the building called Healy Hall at the ground floor. When facing Healy, you can go downstairs using the steps located at the center of Healy Hall, which are flanked by two cannons at each side of the staircase. Take these steps down, go through the door, and walk down the hallway. Enter through the door on the left for GU Politics (G-18). Walk past the television screen and seating area, and you will see the G-02 suite that is the MDI space. Alternatively, you can enter Healy Hall from the first floor and take the elevator (located close to the restrooms and the Bioethics Library) down to the Ground floor, walk down the ramp located on the right-hand side, and enter the MDI suite.
