PurPL is the cross-departmental umbrella group for programming languages research at Purdue University. PurPL research groups push the boundaries of every area in programming languages, software engineering, formal methods, and systems: PL theory, design, and implementation, language-based security, compiler optimizations, verification, program synthesis, and more. But we do more than fundamental research: we bring PL ideas to bear on a wide range of areas, including big data, security, education, and computational science.

Subscribe to the PurPL mailing list following these instructions(name_of_list is purpl) for up-to-date announcements on our weekly seminar series.

Join our Slack channel either via the Purdue CS Slack or through your ECE faculty’s linked Slack connection.
