Supporting courts in their data journey.

I am the Chief Data Strategist at the National Center for State Courts (NCSC), where I contribute new data science tools (data dashboards, database management, predictive and causal inference) to the court community and NCSC's core products, and support courts in developing their AI and data strategies. Prior to the NCSC, I held research positions in government and think tanks, such as UNC's Criminal Justice Innovation Lab, the Center for International Development at the Harvard Kennedy School, the U.K. Foreign and Commonwealth Office, the Brookings Institution, and the Center of Politics and Public Economics (CEPESP-FGV).
