~~NOTOC~~

====== Welcome! ======

The PLEIAD laboratory of the Computer Science Department ([[http://www.dcc.uchile.cl|DCC]]) of the [[http://www.uchile.cl|University of Chile]] ([[http://www.fcfm.uchile.cl|Faculty of Engineering]])  is a newly-created laboratory dedicated to research on new software development techniques.\\

PLEIAD stands for **Programming Languages and Environments for Intelligent, Adaptable and Distributed systems**. We explore how programming language constructs and environments can enable the development of evolvable and highly-adaptable software, particularly considering distributed computing.\\

A non-technical overview of our activities, created for the magazine of the [[http://www.dcc.uchile.cl|DCC]], is available [[articulo|in Spanish]] (original version) and [[articulo_translated|in English]] (translated from the original). \\

===== Research =====
 
Our research is situated at the intersection of Programming Languages and Paradigms, Distributed and Pervasive Computing, and Artificial Intelligence. The main focus is on Software Adaptation in a broad sense.

More specifically, we are involved in [[research]] related to:

  * Computational reflection
  * Program transformations
  * Domain-specific languages
  * Aspect-oriented programming
  * Ambient-oriented programming
  * Distribution and concurrency
  * Biologically-inspired computing and AI
  * Software visualization
  * Code profiling
  * Software Engineering

**Main software artifacts:** 

  * [[http://pleiad.cl/aspectscript|AspectScript]]: an aspect-oriented extension of JavaScript for expressive AOP; integrates several state-of-the-art features related to higher-order programming and expressive scoping of aspects.
  * [[http://pleiad.dcc.uchile.cl/tod/|TOD]]: a practical omniscient debugger for Java, integrated into Eclipse
  * Scheme interpreters and executable semantics artifacts, exploring different facets of [[http://pleiad.dcc.uchile.cl/research/scope|scoping]] in programming language design, in particular for aspect- and context-oriented programming
  * [[Reflex]]: versatile kernel for multi-language AOP
  * [[http://www.moosetechnology.org/|Moose]]: an agile and open software analysis platform

===== Teaching =====

PLEIAD members are involved in teaching various courses. Course information can be found on the [[teaching]] page. Thesis proposals (Engineering and Masters), are on the [[thesis]] page.
