Welcome!

The PLEIAD laboratory of the Computer Science Department (DCC) of the University of Chile (Faculty of Engineering) is a laboratory dedicated to research on software development techniques. Since its creation in 2007, the lab has focused on many ways to better support software development at different levels, from programming languages to development environments. Currently, our work is mostly centered on programming languages, program verification, and type theory.
