Bio:

My name is Isaac Hiram Lopez Diaz. I am a Master's student at Computer Science at UPRRP. Besides computer science and programming, I enjoy watching and playing soccer, and the beach.

Research Goals

  • Contribute to the land of Programming Languages
  • Understand and apply Type Theory
  • Understand Homotopy Type Theory
  • Find the Fourth Futamura Projection :laughing:

Research Description

My research consists of implementing a type checker and interpreter for the RAISE Specification Language (RSL). The hope is that the type checker can later be extended to the semantics of a general purpose language.

Weekly UPDATES

Week 1: (10-14, 3, 2025)

  • Developed scanner for the Language (partially, but mostly completed).
  • Developed a small parser combinator library in order to reuse it whenever language is extended.
  • Develop scanner for RAISE in Scheme.
  • Implement some parser combinators in Scheme.
  • Reading The Seasoned Schemer up to chapter (1)6.
  • Discuss with professor focus on evaluating S-Expressions to develop AST subset and evaluator.

Week 2: (17-21, 3, 2025)

  • Read an axiomatic basis for Computer Programming
  • Read on semantics of programming languages
  • Started developing the Weakest Precondition (Predicate Calculus)

Week 3: (24-28, 3, 2025)

  • Developed weakest precondition for skip, abort, sequence, and if expressions
  • Gave presentation of updates
  • Decided to pursue on proving a 2 line program using weakest precondition
  • Keep developing scanner for the language
