Her first professional career in Development and Fundraising included working for the University of Pennsylvania, University of Oxford, University of Cambridge, and Carnegie Mellon University. Four years ago, she left Development and returned to Penn for a Master of Environmental Studies, focusing on Urban Forestry.
