Building on that work, she is also directing the next round of the Massachusetts Household Insurance Survey for the Division of Health Care Finance and Policy in Massachusetts. Beyond her research in Massachusetts, Dr. Long's current work also includes evaluations of state health reform initiatives in Florida, Illinois and New York.
