Seltzer focuses on Hebrew and Yiddish literature, specifically on the works of Yehoshua Knaz, Ya’akov Shabtai, S. Yizhar, Dvora Baron, Yossel Birstein and Ya’akov Glatshtein in the framework of theories of narratology and the Chronotope by Bakhtin. She also studies Israeli film, and is interested in examining the ways in which literary and cinematic texts complicate the conventional national Jewish narrative.
