So it made for a background of not really knowing where one belongs..."[2] Filloux received her MFA in dramatic writing from Tisch School of the Arts at New York University (NYU) and her French baccalaureate with honors in Toulon, France.

She was first drawn to the subject upon reading of the psychosomatic blindness suffered by a group of Cambodian women after witnessing the massacres of the Khmer Rouge, a story that formed the basis of her 2004 play Eyes of the Heart.

Filloux says of her play, "[It] is written in the staggered poetry of the effort to connect and articulate," grappling with themes of identity, law, sexuality, and family.

[5][6] In a 2008 interview in The Brooklyn Rail, Filloux stated: "For twenty years I have written about Cambodia, P.T.S.D., genocide and trauma.

The play was also part of the 2023 Theater555 Reading Series, produced by the Masterworks Theater Company, with Ylfa Edelstein and Dan Lauria serving as Artistic Directors.

She contributed to the "On Art and Activism" discussion alongside other noted playwrights such as Johnson, Bayeza, and Deen in The Dramatist's May/June 2023 issue.

[14] Additionally, she authored the chapter “Calls to Action: Collaboration across Difference” in the 2024 Routledge publication Theatre Responds to Social Trauma: Chasing the Demons.

Beyond the stage, Filloux has developed five films for the Reimagining Myself transition prison reentry program with Rehabilitation Through the Arts (RTA).
