Recognized for her paintings and drawings that evoke bodily landscapes, Hollowell's work explores themes of sexuality, pregnancy and birth, often through allusions to the human form with an emphasis on women’s bodies. Using geometric shapes to move a figure or its actions into abstraction, her works exist in the liminal space between abstraction and figuration, otherworldly and corporeal. Originating in autobiography with strong colors, varied textures, and geometric symmetry, Hollowell’s practice is situated in lineage with the work of American artists like Agnes Pelton, Georgia O’Keeffe and Judy Chicago. She is also greatly influenced by the work of the California Light and Space Movement as well as Neo-Tantric painters like Ghulam Rasool Santosh and Biren De. Hollowell's work is included in the permanent collections of the Albertina Museum, Vienna; The Aldrich Contemporary Art Museum, Ridgefield, Connecticut; Centre Pompidou, Paris; Crystal Bridges Museum of American Art, Bentonville, Arkansas; Kunstmuseum Hague, The Hague, the Netherlands; He Art Museum, Foshan, China; Hirshhorn Museum and Sculpture Garden, Washington, D.C.; Institute of Contemporary Art, Miami; Lenbachhaus, Munich; Long Museum, Shanghai; Los Angeles County Museum of Art; M+ Museum, Hong Kong; and Stedelijk Museum, Amsterdam among others.
