Katherine Lubar was born in Dallas, and graduated from the Arts Magnet High School for the Performing and Visual Arts in 1987 with a concentration in the visual arts. She received a BA from the Meadows School of Fine Arts at SMU and received a Postgraduate Diploma in Painting from City and Guilds of London Art School in 1999.

She now works and exhibits in London, has exhibited extensively throughout the UK, including exhibitions in Edinburgh. Shows in London have included The London Chamber of Commerce, and The Royal College of Art.

Although the main subject of her paintings is light and its description of space, her paintings often reflect aspects of music. They include a fascination with perspective and the double-sided coin of flatness and depth.
