This line of work culminated in a conference marking the centenary of Michael Schnebel's Die Landwirtschaft im hellenistischen Ägypten. 1. Band: Der Betrieb der Landwirtschaft, with contributions by Walter Otto and Franz Pluhatsch (Münchener Beiträge zur Papyrusforschung und antiken Rechtsgeschichte 7).The related DAI conference, titled Michael Schnebel (1867–1938), die Münchner Papyrologie und die Landwirtschaft im griechischrömisch-spätantiken Ägypten: Tradition und neue Perspektiven, was held in Munich on 18–19 July 2025.

Research and academic work

Yiftach's work centers on the analysis of documentary papyri, which were composed to record everyday activities rather than for literary purposes. His research explores several key areas: Legal Documents and Contracts: Yiftach's research centers on the taxonomy of Greek legal documents, with particular emphasis on the language, syntax, and historical development of contractual clauses in Ptolemaic, Roman, and Byzantine Egypt. In The Taxonomy of the Legal Document, he presents a long-term study of Greek legal documents on papyrus, including a clause-by-clause analysis of 281 contractual formulations, mostly from Egypt, from the early Hellenistic to the late Byzantine period. The work is based on the Synallagma database, a digital corpus first created with the support of the Israel Science Foundation and now hosted at the University of Münster, and combines philological, quantitative, and comparative analysis to examine how scribes encoded rights, duties, and transfers of ownership in legal language. Administrative Documentation: Yiftach has studied the formal conventions of administrative reports and the role of documentary terminology in the functioning of Roman imperial rule. His research explores how reports, classifications, and administrative language organized information and helped sustain provincial government. In parallel, he developed this field further through the German-Israeli Foundation project Synopsis: Data Processing and State Management in Roman Egypt (30 BCE–300 CE), carried out with Andrea Jördens, which examined the handling of reports, accounts, and bookkeeping within the administrative machinery of Roman Egypt. Cross-Cultural Legal Dialogue: Yiftach's work examines the reciprocal influence of Greek, Egyptian, and Roman legal traditions, with particular attention to the processes of Hellenization, fusion, and Romanization in Graeco-Roman Egypt. He has also contributed to the comparative framework of Legal Documents in Ancient Societies, an international research group devoted to the study of legal and administrative systems in the ancient world through documentary evidence. Digital Humanities and Computational Linguistics: Yiftach's recent work integrates digital humanities. He is involved in developing "Cog/PLACTAC," an object-centered annotation framework for scientific and technical texts. This initiative aims to create gold-standard training data from classical authors such as Varro, Theophrastus, Aristotle, and Pliny, enabling downstream AI-based modeling. In addition to co-founding the international research group Legal Documents in Ancient Societies (LDAS) in 2007, Yiftach has organized further collaborative networks on documentary practice. These include "elenchus instrumentorum" and "BotAgrPap," a newer initiative focused on agronomic and botanical evidence across documentary and literary sources.

Selected publications Yiftach's publications have been widely reviewed in prominent classical and papyrological journals, including the Bryn Mawr Classical Review, the Journal of Juristic Papyrology, The Classical Review, and the Journal of Hellenic Studies.
