Professors

Michael Hicks
Mike is co-director of PLUM, having been faculty at UMD since 2002. His research explores the application of programming languages to a variety of domains, most notably software security, but also systems, quantum computing, cryptography, networks, and databases.

David Van Horn
David is the co-director of PLUM, having been faculty at UMD since 2014. He works to make the construction of reusable, trusted software components possible and effective. His research has spanned program analysis; semantics; verification and model-checking; security; logic; complexity; and algorithms.

Leonidas Lampropoulos

Alumni
(This is not a complete list; more as we get time!)

David Darais
David graduated with PhD from PLUM in 2016, working under the superivison of David Van Horn. He is now an assistant professor and core member of the Center for Computer Security and Privacy at the University of Vermont. His research intersects programming languages, data privacy and secure software, and his most recent work focuses on building usable programming languages for differential privacy and secure multiparty computation.

Jeff Foster
Jeff was co-director of PLUM from 2003-2018. Since Fall 2018 he been a Professor at Tufts, and a member of TuPL. The goal of his research is to develop fundamental new ways to make it easier to build more reliable, secure software. He is interested in programming languages, software engineering, and security.

Thomas Gilray
Tom was a Basili Postdoctoral Fellow in PLUM from 2016-2018, working with David Van Horn and Jeff Foster. He is now a co-director of HARP lab (High-performance Automated Reasoning and Programming) at UAB. His research focuses on program analysis design and implementation, frequently drawing on techniques from PL, HPC, and symbolic AI.

Ben Mariano
Ben was a Master’s student from 2017-2019, advised by Jeff Foster. He is now a PhD student at UT Austin working with Isil Dillig. His research uses program synthesis and verification to make programs easier to write and safer to run.
