Sastrowardoyo studied acting with Deborah Savadge beginning in the fall of 1989, ostensibly as a means to help him deal with his shyness. It was instrumental in helping him deal with his brother Sabartomo's death a few years previously. He has also studied poetry with Kimiko Hahn, Richard Tayson and Li-Young Lee; performance with Beau Sia and the Asian American troupe Peeling; playwriting with Julia Cho and David Henry Hwang; photography with Charles Gatewood; dance with Ducky DooLittle and Pamardi Tjiptopradonggo; and writing with Rachel Kramer Bussel and Paul Levitz.
