What university did Georgia O'Keeffe attend in 1914 to study with Arthur Wesley Dow?

Georgia O'Keeffe attended Columbia University in 1914 to study with Arthur Wesley Dow.

She studied at Columbia's Teachers College, where Dow taught art education and composition. His ideas emphasized arranging line, color, and tone rather than simply copying nature. Those principles strongly influenced O'Keeffe's move toward abstraction and her belief that art should express personal experience.

O'Keeffe's time with Dow followed her earlier training at the School of the Art Institute of Chicago and the Art Students League in New York. She did not receive a degree from Columbia University. The relevant institution was Teachers College, Columbia University, so Columbia is the concise university-level answer.
