She earned her Bachelor of Fine Arts from Illinois Wesleyan University in 1994 and her Masters of Fine Arts from the University of Michigan in 2000. Her oil paintings are principally landscape views of picturesque scenes from her travels. A longtime interest in antique maps and in combining art, travel and history has also led her to create her own watercolor pictorial maps. Walker’s Map of the Hamptons, commissioned by the George Glazer Gallery, was featured on a two-page spread in In the Spirit of the Hamptons, a pictorial history and contemporary review of the Long Island beach resort towns by Kelly Killoren-Bensimon (New York: Assouline Publishing, 2002).
