Luís Jorge Rodrigues Semedo de Matos is a Navy Officer, professor at the Naval Academy and associate professor (by invitation) at the Faculty of Arts of the University of Lisbon. He completed the Marine Officers' Course at the Naval Academy (1984), and has a degree in History, a Master’s degree in history of Discoveries and Expansion from the Faculty of Arts and Humanities of the University of Lisbon and a PhD in History, specialising in History of Discoveries and Expansion, from the University of Lisbon. From 2016 to 2021, he was the coordinator of the master’s program in Naval Military Sciences (Marines) at the Naval Academy, and since 2021, he has been the coordinator of the master’s program in Maritime History, a partnership between the Faculty of Arts and the Naval Academy. He is a research associate at the Centre for History of the University of Lisbon and at the Naval Research Centre. His research mainly focuses on Maritime History, namely Naval History (war at sea) and the History of Nautical Science. His doctoral thesis dealt with the Portuguese routes (and rutters) in Southeast Asia in the 16th and 17th centuries, so his research is now centred on Portuguese and Spanish nautical documentation. He paid particular attention to what it reveals about the rivalry, compromise, and complicity between the two Iberian peoples in Southeast Asia. He has worked extensively with students in Naval Military Sciences and in Maritime History programs and has supervised more than a dozen Master's dissertations in the Naval Academy as well as Master's and PhD theses in Maritime History and Military History (Naval). He has been a member of the International Committee for the History of Nautical Science since 1998 and was Secretary General of the Committee from 2000 to 2008.
