I’m most excited to work on projects that… are multidisciplinary, creative, and focused on solutions.

I’m looking for partners that can help me… capitalize on the current policy context to think big about how to protect gains and make positive change.

A moment when I felt most inspired in my work was… during President Obama’s Prague speech.
