Before arriving at the Princeton University Art Museum in 1981, Norman Muller worked at the Montreal Museum of Fine Arts; the Museum of Fine Arts, Boston; the Los Angeles County Museum of Art; and the Worcester Art Museum. In addition to his specialty in painting conservation, he has published numerous articles on nineteenth-century American and fourteenth century Sienese, Italian, and Northern Renaissance painting techniques. In 2000 he was invited by Thomas F. Mathews, professor emeritus of Byzantine art at New York University's Institute of Fine Arts, to join him in a study of ancient Roman votive paintings from Egypt. A corpus devoted to this material will be published by Dumbarton Oaks. In addition to his scholarly activities, Norman lectures in the Department of Art and Archaeology on painting and drawing techniques.
