A central theme in his work is that many graph constructions cannot be fully understood through a single expansion parameter such as the spectral gap; instead, their behavior is often governed by the full spectral distribution of the graph.

As an MIT-Kalaniyot Postdoctoral Fellow, he is jointly appointed in the Department of Mathematics and the Institute for Data, Systems, and Society.

Oded Marck holds a B.A. in Middle East History and Labor Studies from Tel Aviv University, and an M.A. and PhD in Middle East Studies from Ben-Gurion University. His doctoral dissertation, "The Histadrut and the Palestinians in Israel, 1948–1953: Corporatism and Industrial Relations," examines the shaping of Zionist policies toward the Palestinian minority during Israel's formative years and the ways in which Palestinians reacted to, resisted and shaped those policies.

His research focuses on Israel's early years and on the place of Palestinian citizens within the state's emerging political and social order, with particular attention to labor and industrial relations. Centering on the processes that led the Histadrut to reverse its long-standing exclusion of Palestinian workers and permit their partial admission into its trade-union frameworks, and based on extensive Hebrew- and Arabic-language archival research, his work reinterprets Israel's early labor history as a field of negotiation and struggle in which Palestinian workers actively shaped policy and the emerging industrial relations system.

As an MIT-Kalaniyot Fellow and Postdoctoral Associate in MIT's History Section, he studies the history of the modern Middle East and Israel/Palestine, and has published related articles in leading journals in Middle East studies and labor history.
