Professor Hamburger's research focuses on the art of the High and later Middle Ages. Areas of special interest include devotional imagery, mysticism and theology, German vernacular literature, and diagrams. Beginning with his dissertation on the Rothschild Canticles (Yale, 1987), much of his scholarship has focused on the art of female monasticism, a program of research that in 2005 culminated in an international exhibition, Krone und Schleier (Crown and Veil). Recent exhibitions include Unter Druck: Deutsche Buchmalerei im Zeitalter Gutenbergs (Munich-Vienna, 2015) and Pack Day Backpack Small Sack Back Highlander Rucksack Adventure Gym Travel School Shoulder Red 20L Bag Beyond Words: Illuminated Manuscripts in Boston Collections (2016). Imperial Splendor, an exhibition of Central European manuscripts in American collections, is planned for the Morgan Library, NY, in 2021. Other recent work includes The Prayer Book of Ursula Begerin (Zürich-Dietikon, 2015), co-authored with Nigel Palmer (Oxford), and Liturgical Life and Latin Learning at Paradies bei Soest, 1300–1425 (Münster, 2017), co–authored with Margot Fassler, Susan Marti & Eva Schlotheuber. Forthcoming are The Liber ordinarius of Nivelles: Liturgy as Interdisciplinary Intersection (Tübingen, 2019) and From Cross to Crucifix: Typology, Diagrams and Devotion in Berthold of Nuremberg's Commentary on Hrabanus Maurus' In honorem sanctae crucis (2019). The recipient of numerous awards, including fellowships from the John S. Guggenheim Foundation, the American Philosophical Society, the NEH, Dumbarton Oaks, and the Humboldt-Stiftung, Prof. Hamburger was elected a Fellow of the Medieval Academy of America in 2001, a member of the American Academy of Arts & Sciences in 2009, and a member of the American Philosophical Society in 2010.
