Mark Ottoni-Wilhelm is professor of economics at IUPUI and professor of philanthropic studies at the Indiana University Lilly Family School of Philanthropy. He conducts empirical research on prosocial behavior. He has published articles about altruistic motivation behind voluntarily giving money, the intergenerational transmission of generosity, experiences of family instability/low income during adolescence and subsequent giving/volunteering in young adulthood, empathic concern and moral principles as correlates of prosocial behavior, and the relationship between religious affiliation and giving to organizations that help people in need.

Ottoni-Wilhelm was the founding director of the ongoing Philanthropy Panel Study (PPS), the generosity module in the United States’ Panel Study of Income Dynamics. Since 2001 the PPS has generated the United States’ authoritative family-level data on charitable giving. Ottoni-Wilhelm continues to provide scientific support to the PPS, and makes user-friendly data files and user guides freely available. He has also led the design of generosity modules that are included in the American National Election Study 2008-2009 Panel, the National Study of American Jewish Giving, and the National Study of American Religious Giving.
