Benjamin C. Pierce

Benjamin C. Pierce is the Henry Salvatori Professor in the Department of Computer and Information Science at the University of Pennsylvania's School of Engineering and Applied Science. He leads research in programming languages, type theory, and software verification, with significant contributions to property-based testing through his work on the Tyche framework. Pierce is deeply involved in academic service, serving on program committees for major conferences including PLDI, OOPSLA, and POPL, and has held editorial roles for prestigious journals such as the Journal of Functional Programming.

His research spans multiple areas including automated reasoning, property-based testing, programming language theory, security and privacy, and bidirectional programming. Pierce has made foundational contributions to type systems, programming language semantics, and formal verification. His recent work focuses on practical applications of property-based testing, with numerous publications on the Tyche framework and related tools that help developers understand and improve testing effectiveness. He also maintains significant interest in climate change research as it relates to academic conferences and virtual events.

Pierce's publication record shows a clear trajectory toward more practical applications of formal methods, particularly in property-based testing. His recent articles demonstrate a focus on making verification techniques more accessible and useful for practicing developers, with strong emphasis on visualization, usability, and empirical validation. The research spans theoretical foundations to practical tools, reflecting his commitment to bridging the gap between programming language theory and real-world software development.

Among his notable achievements are the 2023 Amazon Research Award for TYCHE: An IDE for Property-Based Testing and a Distinguished Paper Award in 2020 for "Interaction trees: representing recursive and impure programs in Coq." His influential textbooks, including "Types and Programming Languages" and the "Software Foundations" series, have educated generations of computer scientists.

Pierce actively mentors PhD students, with recent advisees including Li-Yao Xia ("Executable Semantics with Interaction Trees"), Yishuai Li ("Testing By Dualization"), and Harrison Goldstein. He has secured significant research funding through collaborations with industry partners like Amazon and has been instrumental in developing frameworks for deep specification and verified systems.

He co-leads initiatives addressing climate change impacts on academic conferences, serving on the ACM Presidential Task Force that produced "Virtual Conferences: A Guide to Best Practices" during the pandemic. His work on carbon offsets for scientific societies has influenced policies across multiple professional organizations.
