[2] While establishing and building the contemporary art department at the Israel Museum, Landau identified and acquired works by that time young artists who were just at the beginning of their career, such as Jean-Michel Basquiat, Damien Hirst and Maurizio Cattelan among others.

In her 34-year tenure at the Israel Museum, Landau presided over several internationally famous solo and group exhibitions,[3][4][5] among them Anselm Kiefer (1984), Jenny Holzer/Barbara Kruger (1986), New York Now (Peter Halley, Jeff Koons, Sherrie Levine, Allan McCollum, Peter Nagy, Haim Steinbach, 1987), Christian Boltanski (1989), Life-Size (1990), Gerhard Richter (1995), Marks (with Sarkis, Juan Munoz, David Hammons, 1996), Yinka Shonibare (2002), Still-Moving (2010), William Kentridge (curator in-charge, 2011), Beyus/Kantor (with Jaromir Jedlinsky, 2012).

[6][7] Landau began a collaboration with businessman Steve Nassima in late 2020, after the Israeli government permitted the limited reopening of the nation's largest museums.

[3] Following her appointment, Landau initiated numerous exhibitions including artists like Absalon, David Claerbout, Fiona Tan, Michael Borremans, Elmgreen & Dragset, Alina Szapocznikow, Taryn Simon, R. H. Quaytman, Hiroshi Sugimoto, and launched site specific projects in the Museum’s Light Fall of Douglas Gordon, Joanna Vasconselos, Tom Friedman and Ibrahim Mahama among others.

Landau curated exhibitions of Ydessa Hendeles, Christian Marclay, The Clock, Louise Bourgeois Twosome (with Jerry Gorovoy), Modern Times, Masterpieces from the Philadelphia Museum and Yayoi Kusama A Retrospective.
