Peter is a research scientist in the Conflict Resolution and Coexistence Program at Brandeis University's Heller School for Social Policy and Management. He is also a co-principal investigator at the peacebuilding and research NGO, Everyday Peace Indicators. He is interested in how the everyday experiences of people and organizations during and after conflict enable or limit transformative solutions toward peace and justice.

Currently, he is working on reparations and truth processes in Colombia and the Democratic Republic of the Congo and on social justice processes in the United States. A sociologist by training, he works with interdisciplinary teams of political scientists, legal scholars, and peacebuilders, drawing on qualitative methods like focus groups and quantitative methods like population surveys.
