[1] She is best known as the author and illustrator (or, as Halliday herself terms it, "the chief primatologist") of the long-running zine The East Village Inky.

[2] The zine got its name from Halliday's living in New York City's East Village, and "Inky" being the nickname of her then-infant daughter India.

[3] Her first graphic novel, Peanut, was published in December 2012 and was positively reviewed by The New York Times.

She attended Park Tudor School and Northwestern University, where she obtained a degree in theater performance.

Halliday created and hosts Necromancers of the Public Domain, a monthly performance series in New York City, wherein a dusty book from the New York Society Library is turned in a low budget variety show.
