I am a cultural and comparative-historical sociologist with research on altruistic behavior, transnational solidarity, and morality. My research explores how beliefs about the common good shape a variety of social sites by focusing on the ways discourse about morality is used to justify the existence of practices and institutions. I am currently a Lecturer at the Department of Sociology at Harvard University, where I teach courses on Humanitarianism, Philanthropy, and Social Trauma.
