research interests span civil law, European private law, Roman law and papyrology. He has published work on a variety of subjects related to law, papyrology, and the ancient world, including archaic Roman law, matters of classical private law, the administrative and public law of the later Roman Empire and the reception of Roman law in Europe and in the former Dutch East Indies. He is co-author of the standard edition of the Pommersfelden Papyri. The Theodosian Code and the colonate in the Roman empire are particularly subjects of research. His Food for Rome: the Legal Structure of the Transportation and Processing of Supplies for the Imperial Distributions in Rome and Constantinople (1991) developed from the thesis for his doctoral degree at Amsterdam, completed in 1984. Following the death of the Dutch papyrologist Pieter Johannes Sijpesteijn in 1996, Sirks edited with K. A. Worp a collection of previously unpublished papyri dedicated to Sijpesteijn's memory by his fellow papyrologists, including papyri from the Hellenistic, Roman and Byzantine periods, to reflect Sijpesteijn's wide interests.
