Jankowski graduated in Classics (Licence and Maitrise at the Université Paris-Sorbonne), in Chinese (Licence at the Institut National des Langues Orientales, Paris), in Antiquity (Magistère at the Ecole Normale Supérieure) and in Art History (Licence, Master and Doctorat at the Université Paris-Sorbonne). Her studies of the contacts between Imperial Rome and Han China sparked an interest in numismatics. She studied Chinese numismatics with
François Thierry (numismatist), curator of the Asian coin collection at the
Bibliothèque Nationale de France (BnF); numismatics at the
American Numismatic Society E. Newman seminar; Greek and Roman coinage in Paris with
Olivier Picard and
Michel Amandry; and Central Asian numismatics with
Osmund Bopearachchi. For her PhD, she explored the social networks of coin collectors in 19th century China. The title was "Les cercles de collectionneurs et de numismates dans la région de Pékin durant la première moitié du XIXème siècle". From 2014 to 2017 she was a fellow of
Worcester College, University of Oxford, and Sackler Fellow at the
Ashmolean Museum, where she curated the East Asian and subsequently adjunct professor in the Department of East Asian languages and civilizations. In 2019, she became Curator of extra-European arts at the
Musée royal de Mariemont, Belgium. == Awards and honours==
