  • Ivuoma “Ivy” Onyeador

    YC ’11 · National President

    Location
    Chicago

    Ivy is an Assistant Professor in the Management and Organizations Department at the Kellogg School of Management at Northwestern University. Her research is motivated by a contradiction: while equality is ostensibly a core American value, the United States is marked by a profusion of inequalities, and when confronted with evidence of those inequalities, many Americans’ first impulse is to deny, dismiss, or justify them. Her involvement with YBAA began as a student and has continued through committee leadership, chapter work in Los Angeles and Chicago, and service as Interim Vice President during the 2023 relaunch.
