She gained recognition for her series Velocity (1998), which featured her mother's paintings projected onto her body. Rossiter participated in the artist collective fierce pussy (1991), worked at Pat Hearn Gallery, co-founded ART CLUB 2000 in collaboration with Colin DeLand at American Fine Arts Co. (1992), and established Velocity Gallery in Brooklyn (1997), where she exhibited emerging women artists.

Rossiter’s solo show in Chelsea in September 2001 expanded on her performative interests with painterly scenes from California and Hawaii, but after witnessing the attacks in NYC on September 11th, her work began to repeatedly depict her own death. In 2003, she made her last performative work in Amden, Switzerland, with scenes of ritual and rebirth, moving from a perspective of resistance to a more expansive state of awareness.

In Los Angeles in 2006, she exhibited large-scale photographic and sculptural installations, creating immersive experiences where scenes of nature and architecture became portals. She photographed crystals, bodies of water, and flowering trees, interested in their abstract visual power and consciousness.

In 2010, Rossiter returned to painting, developing a process that disengaged the mind and allowed further experimentation with material and color. Since 2019, she has worked nomadically, making abstract paintings that function as energetic imprints of locations including New York, Hawaii, Mexico and Paris.

Her first exhibition of paintings, titled “Imprint,” in March 2025 was the culmination of a studio practice which involved making performative paintings on the floor and pressing the canvas onto them. In May 2025, Rossiter’s new performative photographs depicting the artist’s body interacting with the imprint painting source materials, was shown at the same gallery in Italy.

Rossiter has exhibited widely in the US and internationally, including Germany, Italy, Spain and Switzerland.

Collaborative work made with ART CLUB 2000 from 1992-1993 has been featured in retrospective exhibitions in Mexico at the Carrillo Gil Art Museum, in New York at the New Museum and ARTISTS SPACE, and in Switzerland at the Kunsthalle Zürich.
