Welcome!

The [PLEIAD](https://pleiad.cl/pleiad-history) laboratory of the Computer Science Department ([DCC](http://www.dcc.uchile.cl/)) of the [University of Chile](http://www.uchile.cl/) ([Faculty of Engineering](http://www.fcfm.uchile.cl/)) is a laboratory dedicated to foundational and applied research on software development techniques.

Since its creation in 2007, the lab has focused on many ways to support the development of high-quality software at different levels, from programming languages to development environments. Currently, our work is mostly centered on programming languages, program verification, and type theory, as core approaches to address concerns of correctness, efficiency, robustness, data privacy and security.
