Tumbas’s teaching and research fields focus on modern and contemporary art and theory, histories and theories of performance, body and conceptual art, art and activism, politics of contemporary visual culture, feminist art, and critical theory. She is currently working on the completion of her manuscript, which analyzes how artists used performance and conceptual art in former Yugoslavia to highlight socially suppressed aspects of sex and gender and questioned what the public could do to resist the normative parameters of social relations, civic engagement, and political consciousness. Tumbas’ second book project engages with the question of ethnic Roma in East and Central Europe, the largest and most discriminated minority in Europe predominately left out of histories about avant-garde art in the region.
