Transparent Engagement 

Harvard Kennedy School is proud of its energetic involvement in the world. To better understand how to solve public problems by improving policy and leadership, we engage directly with policymakers, public leaders, governments, nonprofit organizations, and for-profit businesses whose activities affect those problems. However, we recognize that such engagement can raise questions about perceived and potential conflicts of interest, so we disclose publicly the key professional activities of our faculty outside the Kennedy School. The activities disclosed below are for the most recent reporting period, as defined by University policy. Some may be paid, some may be unpaid, and others may be in exchange for expense reimbursement only.
