I graduated in Archives and History at The University of Comenius in Bratislava and in Lettere Moderne at La Sapienza University in Rome. In 2002, I was awarded my Ph.D. in Medieval Ecclesiastical History at Comenius University after I defended my doctoral thesis "The Hungarian Policy of Gregory IX with a Special Focus on the Territory of Slovakia (1227-1241)".
From 1996 until 2004 I was employed as a Researcher in Slovak Medieval History at the Historical Institute of the Slovak Academy of Sciences. Following a decision of the Academic Board of the University of Péter Pázmany in Hungary in January 2004 I was given 'venia legendi' and held a course "The History of Medieval Universities". In 2005 I was invited to join the staff of the Vatican Library where I remained for three years; during this time I also studied at the Vatican School of Library Science.
Since 2010 I have been delivering a series of lectures for the Final Honour Schools (General History V, VI) entitled "The Thirteenth Century Papacy - The First Multinational?" which attracted interest from undergraduates, postgraduates and doctoral students equally and I am also contributing some lectures on British History II for the Preliminary Examinations and the History of the British Isles II for the Final Honour Schools. In January 2011, I was elected Director of the London Society for Medieval Studies.
I have conducted research in the Archives of Slovakia, Hungary, Italy and the Vatican City on Slovak Medieval History and Slovak-Hungarian-Italian relationships the results of which I published and presented both in Slovakia and abroad. My main areas of interest are Central European History, the History of Medieval and Modern Universities and the Medieval Papacy.
