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.
