Katie Miller was born and raised in the wilderness of Northeastern Minnesota's Iron Range, but is now deeply rooted in the Pacific Northwest. Miller’s interdisciplinary practice is situated at the intersection of art, architecture, and science, and is rooted in research, experimentation, and observation. Miller received a BFA in sculpture from the University of Washington and an MFA in glass from the Tyler School of Art.

Miller’s solo exhibition, Overburden appeared at the Vestibule in 2024. Her creative practice has been supported by 4Culture, Seattle Office of Arts & Culture, PLAYA: Center for Art & Science, Puffin Foundation, Seattle Art Museum, Joshua Tree Highlands, MadArt, Montello Foundation, McMillen Foundation, Bullseye Glass Factory, Method Gallery, Artist Trust, Art Farm, and Pilchuck Glass School among others.

Her work has been exhibited nationally in museums, galleries, and artist-run spaces. Her work can also be found in 4Culture’s public art collection at Harborview Medical Center, as well as in public and private collections including Washington State Public Art Collection, King County Portable Works Art Collection, Amazon, MadArt, Hoedemaker Pfeiffer, and others.
