For over a decade, her research has focused on education spending and productivity, digging deep into education spending records to follow resources as they are deployed across schools, classrooms, and students. Much of her work traces spending patterns back to the various policy decisions that prompted them. Her analyses of fiscal policies and their implications for resources at school and classroom levels have prompted changes in education finance policy at all levels in the education system. She has written more than 40 articles and monographs in a wide variety of publications. Currently she serves as a nonresident senior fellow at the Brookings Institution, at Education Sector, and at the Rockefeller Institute.
