Research
Frier's research is focused in Roman law and legal history, Roman social, economic, and demographic history, alongside an examination of Hellenistic and Roman historiography, specifically the works of Polybius, Sallust, and Livy. Additionally, he is interested in exploring legal theory, sociology of law, classical and modern rhetoric, and related disciplines. Du Plessis delivered a comprehensive review of the Festschrift honoring Bruce Frier, Ancient Law, Ancient Society. He analyzed the volume's contents, chapters, and themes while underscoring the intellectual significance of Frier's scholarship and his scholarly legacy. Du Plessis also noted that, “Frier, like a veritable Irnerius, has profoundly influenced the study of Roman law in the Anglophone world, both through his own work and that of his former students.”

Roman legal, economic and social history
Throughout his career, Frier has contributed to the field of Classics and Roman Law, authoring numerous publications. Shedding light on the social and economic conditions of ancient Rome, he suggested a more complex model of the rental market than previously thought, highlighting that the range of accommodation available to the urban masses was often effectively limited by the wealth and other social characteristics of the prospective tenant. One of his earliest works, Landlords and Tenants in Imperial Rome, provided a sociological understanding of law in imperial Rome and law's role in premodern societies. He used archaeological data, literary texts, and legal texts to demonstrate that the upper class, including senatorial families, lived in rented apartments, and that the Roman law of urban lease was primarily intended for them rather than the lower class. Honoré called it a “fascinating contribution to Roman legal history that has implications for legal theory and comparative law”.

Having called Frier a "classicist who has acquired a remarkable understanding of the legal process", Stein stated that, "Frier gives us a detailed study of the law of urban leases, related for the first time to the reality of the Roman rental mark". Whereas, highlighting the need for a more comprehensive analysis, Triantaphyllopoulos wrote that it is, "original and opens new avenues for the study of Roman law, I hope the author overcomes his expressed scruples and extends his study to the lower classes and Roman Egypt."

Afterwards, in his work, The Rise of the Roman Jurists: Studies in Cicero's "Pro Caecina", Frier discussed the factors that led to the professionalization of law during the later Roman Republic. According to Gordon, the book is an "effective interdisciplinary study," Cohen regarded it as "a rich and exciting treatment of an important topic," Birks praised Frier's scholarship and "firmness of judgment and clarity of exposition," and Watson found it "stimulating" despite disagreeing with its conclusions. 

Among the other subjects, Frier has addressed in his articles and books are Roman demography, natural fertility and family limitation in Roman marriage, the Roman origins of public trust doctrine, the economy of Greece and Rome, Cicero's urban property management, and the development of Roman private law and the judicial system during the 70s and 60s BCE.

In summing up the method that Frier developed in his scholarship, Du Plessis observed that: "while it acknowledges the importance of the different generations of Roman jurists, it goes much further in trying to contextualise their positions. ... [W]hat sets Frier’s scholarship apart is his training in the common law and his engagement with legal realism and the sociology of law."

Frier also led a team of scholars of Roman law as the General Editor of The Codex of Justinian translation project. The team based their translation on the manuscript of Fred H. Blume, who translated the text in the 1920s; it had remained unpublished for almost a century until it was rediscovered in the library of the University of Wyoming Law School. In a review of this 2016 editorial work, Zetzel described the translation as "impressive" and commended the careful handling of technical legal terminology, noting that "where literalism is impossible, the Latin phrase is repeated in parentheses within the translation for clarity; technical passages are often annotated". Du Plessis acknowledged him for explaining the project's aims and complexities, was of the view that "this should be required reading..." and highlighted that "There are also important issues about the 'apparatus criticus' that are worth noting."

Casebooks on Roman law
Frier's work in Roman law has featured several casebooks, including those on Roman family law, the Roman law of contracts, and the Roman law of delict. He developed the delicts casebook, modeled after Herbert Hausmaninger's German casebooks on Roman property and contract law in 1989 for his Roman law courses. Focusing on the Roman law of private wrongs akin to Anglo-American torts, he presented 171 cases from pre-classical and classical jurists' writings, while introducing fundamental principles of Roman law and their impact on contemporary legal systems. Watson acknowledged him as the "most distinguished American scholar of Roman law" and commended the book as an "excellent introduction for the college Classics student to the law school experience," Johnston emphasized its usefulness as a teaching tool to introduce students to "some notion of the individuality of the jurists," and Harrington characterized the work as "well done and useful…because it relies upon the original Latin sources followed by a translation and explains legal principles in a clear and effective manner." Building on this foundation, his next book, A Casebook on Roman Family Law, co-authored with McGinn, providing insights into Roman social history and offered an in-depth analysis of Roman family law during the early Roman Empire, with a focus on the legal aspects of Roman households. Through 235 representative legal texts, it also provided an introduction to the basic legal issues related to the ordinary families of Roman citizens. Bradley in his book review regarded the book as "far more than a teaching text and... welcome contribution to Roman family studies at large."

Over the past few decades, Frier has focused his research studies on contract law. In A Casebook on the Roman Law of Contracts, he explored the writings of Roman lawyers regarding the law of contracts, with particular emphasis on stipulation and sale. The book featured 235 cases from the Digest of Justinian, offering a comprehensive view of contract rules and judgments in Roman courts, and also discussed other contracts, contract-related issues, and Roman legal thinking on unjustified enrichment. His continued investigations into this subject have also led to the publication of a law textbook The Modern Law of Contract (now in its 4th edition), which provided coverage of key topics for LLB and GDL courses in 2022.
