From 1993 until 1997 she was Rare Books Conservator and Collections Conservator at Yale University Library.


DAVID RATZAN holds degrees in Classics from Yale and Cambridge Universities (Clare College), and a Ph.D. in Classical Studies from Columbia University (2011). His research is in the social history of the ancient world, with a current emphasis on the economic and legal history of the Roman Empire.  He is currently the Head Librarian of the Institute for the Study of the Ancient World at New York University.  He has served as the Curator of Papyri in the Rare Book and Manuscript Library in Butler Library, where he organized research, teaching, outreach, and digital projects related to the papyrus and epigraphy collections.  He has published extensively on various topics related to law, economics, and society in the ancient world.

ROGER BAGNALL is Leon Levy director emeritus of the institute for the Study of the Ancient World and Professor of Ancient History at New York University.  Before joining the NYU faculty in 2007, Bagnall was Jay Professor of Greek and Latin and Professor of History at Columbia University, where he had taught for 33 years. During that time he served as Dean of the Graduate School of Arts and Sciences and Chair of the Department of Classics. Educated at Yale University and the University of Toronto, he specializes in the social and economic history of Hellenistic, Roman and Late Antique Egypt. He has held many leadership positions in the fields of classics and papyrology; he is co-founder of a multi-university consortium creating the Advanced Papyrological Information System. He is a member of the American Philosophical Society as well as a Fellow of the American Academy of Arts and Sciences and the British Academy.

SARAH GOLER received her undergraduate degree from Columbia University in Applied Physics where she explored the structure and properties of graphene, a single sheet of carbon atoms one atom thick, using Raman Spectroscopy.  She then undertook her PhD studies in Experimental Condensed Matter Physics at the Scuola Normale Superiore in Pisa, Italy.  In her PhD studies she studied fundamental properties of graphene as a potential material for hydrogen storage.  Her work is widely recognized within the world-wide Nanotechnology community.  In addition to this solid base in Nanoscale solid state physics, Ms. Goler has a wide range of interests including Art and Art history. She was recently a Fellow of the Italian Academy at Columbia University.


ANGELA CACCLOLA graduated in 2015 with a bachelor’s degree in chemistry from Barnard, the women’s college at Columbia University.  A natural, immersion learner, over the course of her postsecondary career Angela supplemented her coursework with diverse experiences at blueEnergy Nicaragua, the US Naval Academy and the multidisciplinary Ancient Ink Laboratory at Columbia University.  She also gained a love for science investigating how free radicals control the function of the heart’s mitochondria in Szweda lab at Oklahoma Medical Research Foundation.  This heterogeneous education has instilled in her passionate desire to pursue a water-related profession.  She is currently a graduate student at MIT studying environmental organic chemistry in the department of civil and environmental engineering.
