As a university professor, Falk taught Hebrew and English literature, Jewish studies and creative writing at Stanford University, Binghamton University, and the Claremont Colleges. In 2001 she was the Priesand Visiting Professor of Jewish Women’s Studies at Hebrew Union College in Cincinnati. Falk is a life member of the Art Students League of New York, where she studied painting as a child and adolescent. Her painting "Gilead Apples" was used as the cover illustration for her book The Days Between: Blessings, Poems, and Directions of the Heart for the Jewish High Holiday Season. She has also created a series of mizrachs featuring oil pastel paintings accompanied by texts from her volume of Hebrew and English prayers, The Book of Blessings. Falk’s poems have appeared in the American Poetry Review, Choice, Moment, Poet & Critic, Poetry Society of America Magazine, Her Face in the Mirror: Jewish Women on Mothers and Daughters, September 11, 2001: American Writers Respond, Voices Within the Ark: The Modern Jewish Poets, Fire and Rain: Ecopoetry of California, and many other magazines and anthologies. She has published three collections of her own poems: My Son Likes Weather,This Year in Jerusalem, and It Is July in Virginia. Falk is also the author of The Spectacular Difference: Selected Poems of Zelda, a volume of translations of the Hebrew poetry of twentieth-century mystic Zelda Schneerson Mishkovsky, and "With Teeth in the Earth: Selected Poems of Malka Heifetz Tussman." The Song of Songs: Love Lyrics from the Bible, a classic verse translation of the biblical Song of Songs, was first published in 1977. The poet Adrienne Rich called her translation "a beautiful and sensual poem in its own right." 1996's The Book of Blessings: New Jewish Prayers for Daily Life, the Sabbath, and the New Moon Festival was acclaimed for its nongendered depictions of the divine, replacing traditional masculine terminology for God with what Falk calls "new images for divinity." Writing in The Women's Review of Books, Judith Plaskow hailed the book's "extraordinarily beautiful prayers," which use "no female images and little feminine grammar. Instead, evokes the sacred as totally immanent in creation, offering an alternative to the whole notion of God as male or female person." The Days Between: Blessings, Poems, and Directions of the Heart for the Jewish High Holiday Season, published in 2014, takes a similar approach to the High Holy Day season, recreating the holidays’ key prayers and rituals from an inclusive perspective. Rabbi David Teutsch of the Reconstructionist Rabbinical College praised the author for demonstrating "a poet’s gift for words that open inner vistas, a liturgist’s capacity to speak to the universal, a scholar’s insight into Jewish traditions and texts, and a contemporary feminist’s fresh vision." She published Inner East: Illuminated Poems and Blessings in 2019. Falk lives in Berkeley, California, with her husband, the poet Steven Jay Rood; they have one son, Abraham Gilead Falk-Rood.
